Your help is needed to protect beach-nesting birds, nests, and young. Conservian is planning for Year 3 of their shorebird and habitat conservation program in the Bahamas. Come join them for the adventure of a lifetime!

BirdsCaribbean, the Bahamas National Trust and Conservian are seeking a weekly crew of 8 to 10 enthusiastic volunteers for our Bahamas shorebird and seabird habitat conservation project in May 2018 aboard our 75ft schooner research schooner. This is an excellent opportunity to gain field experience and shorebird ID skills. Trip cost for one week is $1,350 and includes your bunk, onboard meals, water, and ground transportation associated with project. Participants will fly to the Bahamas each week to designated airports for shuttle transport to schooner. A valid passport is required. Airfare and insurance are not included.

Project Summary

We need volunteers to help count birds and remove invasive plants from coastal habitats. This year we are visiting the Exuma Cays including two of the world’s largest Audubon’s Shearwater colonies and the world’s first and most beautiful Land and Sea Park. We are also going to the Joulter Cays and Andros for a week to some of the most important Piping Plover winter habitat. Both trips have ample opportunities to enjoy the beaches, islands, reefs, and marine life of the Bahamas while helping conserve the birds and other wildlife.

Our days will be filled with much adventure aboard the 75ft schooner “Avalon”. (photo by Margo Zdravkovic)

Our days will be filled with much adventure. The focus of the work is surveying for beach-nesting bird breeding pairs, nests and young, and working with local volunteers to implement protective measures in the field. Focal species include Wilson’s Plovers, American Oystercatchers, Least Terns, Audubon Shearwaters and other colonial nesting species. We will work in both populated and remote areas, sail blue Caribbean waters, visit white sandy beaches, boat to little islands, conduct ground surveys for beach and cay nesting birds, nests, and downy chicks, and meet new people. We will work with local volunteers to post and sign shorebird sites and control invasive Australian pine. Field crew will assistant with collecting data on breeding pairs, habitat assessment and human-created disturbance. Field crew will also assist with shipboard duties; sailing, cooking and cleaning. There will be time to fish, snorkel, enjoy the breath-taking beaches, and visit local island towns.

Project Activities:

Protect, post & sign shorebird & seabird sites
Collect new data on nesting shorebirds, seabirds & habitat
Locate and protect shorebird & seabird nests and downy young
Observe/assist with bird banding (conditions permitting)
Control invasive Australian pine on beach habitats
Work with local volunteers to accomplish the above goals
Snorkel reefs in gin clear waters
Learn saying crew skills
Fish for dinner-catch of the day!

Qualifications: Applicants must be responsible, adventurous, in good physical condition, enjoy working in teams and be capable of walking several miles during warm weather in the Caribbean.

Winners of BirdsCaribbean Photo Contest 2017

Grand Prize Winner—Cuban Tody by Gabriel Lugo

BirdsCaribbean’s second biennial photography competition took place at our 21st International Conference in Cuba, July 2018. The three judges thoroughly enjoyed looking through 72 photos submitted on BirdsCaribbean’s Flickr (look for tag “BCPhotoContest2017”) by many fine photographers.

This year’s contest featured three distinct categories as well as an overall Grand Prize Winner. The Endemics category showcased the bird species found only on Cuba. Fun with Birds and People highlighted both human-bird interaction and the International Conference itself. Birds and Nature explored birds as well as their habitats and the other animals and plants that make up island ecosystems.

The judges had a challenging time deciding on the winners in each category—they considered composition, focus, colour and overall interest of each photo. After some debate, the judges were unanimous in their decisions for the following prize winners.

Captured! by John Webster - First Prize winner in Fun with Birds and People category — Captured! by John Webster – First Prize winner in Fun with Birds and People category

Fun with Birds and People

First Prize – Captured! by John Webster, with a fun backstory: A local Cuban woman (not attending our conference) was painting a Belted Kingfisher using an illustration from Herb Raffaele’s Birds of the West Indies Field Guide as a reference. Herb, the good birder he is, spotted her working on the painting that was to be sold to the next tourist. Naturally, Herb was intrigued. Not knowing her understanding of copyright, he introduced himself as the author of the book. She was shocked and a little sheepish to be caught copying the artwork. This amazing moment was well captured by John Webster. In the end, to properly honor the author, she presented him with the freshly rendered kingfisher. ¿¡Que suerte?!

The Mystery of the Missing Todies: Understanding the Impacts of Invasive Mammals

Invasive mammals are known to be a problem on many islands. Holly Garrod shows first-hand how some of these pesky species are causing nest failure for one of the Caribbean’s most well known and best loved birds—the tody.

It was a muggy afternoon, typical for the summers in Jarabacoa, the central region of the Dominican Republic. Rubber boots on and camera in hand I was making my way through the creek system of a local farm. The goal was to check Broad-billed Tody nests. I was in the first field season for my master’s research, studying the breeding biology and behavioral interactions of Hispaniola’s two tody species: the Broad-billed Tody (Todus subulatus) and the Narrow-billed Tody (Todus angustirostris). One aspect of my research included how non-native mammals were affecting their breeding success. I had dubbed the creek I walked through as “tody neighborhood” (or barrio de barrancolis in Spanish), due to the high volume of nests I had found, totaling up to 15 in that one creek alone. I anticipated it would be one of my most productive sites this year, little did I know I was to be wrong.

But before I get into the mystery at tody neighborhood, let me explain some basic tody facts. Todies, while appearing to look like our pollinating hummingbird friends, are actually more closely related to kingfishers. Interestingly enough, todies are one of only two families of birds that are endemic to the Caribbean (the other being Dominican Republic’s national bird – the Palmchat). Within their Family Todidae, there are 5 species distributed throughout the islands of the Greater Antilles, most of which are named for the island they’re found on, excepting the aforementioned Hispaniolan todies. This interesting phenomenon, where Hispaniola is the only island to have two tody species, is the baseline for my master’s research, and the reason I was walking through creeks searching and monitoring for tody nests.

Now when most people hear “bird nest,” they think of an assemblage of twigs and moss carefully placed among the branches. But todies are different. For their nests, the pair chooses a dirt bank, then takes turns digging a burrow using their beaks. Typically, the burrows end up being about 10-15 cm deep, with some of them curving and all of them having an enlarged chamber at the end. With their preference for dirt banks, the best place to look for these burrows ends up being creeks.

Which brings us back to tody neighborhood. Walking through the creeks, notebook in hand, I stopped at the first nest. It was still early in the season, late May, and from my last check I knew all the nests had eggs. Now it was just a matter of seeing when they would hatch. I used an endoscope camera to check the nests, a long bendable tube with a camera and light on one end, where the other end hooked up to a monitor, providing live-stream tody footage. I slid the camera into the first nest, seeing nothing. Knowing that this nest had a tricky curve, I tried for several more minutes until something appeared, a cricket. Oftentimes when the todies finish breeding, other animals will move into the unoccupied cavities; typically large cave crickets are the most common. For this reason, todies almost always construct a new burrow every year. Presence of the cricket meant the nest had failed.

I continued to the other nests, hoping to have better luck. I breathed a sigh of relief as I saw the next nest still had the three eggs noted from several days earlier. But that’s where my luck ended. The next 5 nests had failed. I was baffled, from all outward appearances the nests appeared fine: the holes were still the same size and there were no signs of forced entry or tracks around the banks. When I returned several days later, it was more bad news. More failed nests and still mostly no signs of the culprits. Several nests appeared as though they may have been enlarged, but most others maintained the same outward appearance. Who could be predating these tody nests?

This is a Broad-billed Tody chick at 13 days old. I banded chicks between 12-14 days because at that point they were most developed. Chicks typically fledged (left the nest) around 14 days after hatching. (Photo by Holly Garrod)

I started putting up camera traps (part of my funding from the David Lee Grant), hoping to get footage of what was happening at these nests. The idea being, the camera traps are motion activated and start recording with the presence of movement. I set one up at one of the few remaining active nests in tody neighborhood, scattering the others at nests in other creeks. One week later, I returned to glean the videos. Sitting back at the field house, going through the videos I was disappointed with the first two cameras. Most of the videos showed twigs moving or people walking by, the angle looking slightly off to catch the curprit.

Then I came to a night picture. I was about to pass by when I saw the outline of a cat walking by. Suspect number 1. Yet when I checked the records that nest had fledged successfully when I retrieved the camera. Plus a cat would have to have caused some external damage to the nest hole to access the tody. Ruled out as the common culprit, but still a potential predator.

The next set of videos I pulled up began with a night shot. I waited several seconds and then suspect number 2 appeared: a rat. I watched several videos of what I can only assume to be the same rat climbing on logs and scurrying around. Video after video I watched the rat run around, but appear oblivious to the nest entrance. Finally, watching the rat take its usual stroll around the log, I saw it. The flicker of interest in the nearby nest hole. I watched as the rat approached, holding my breath. There was no way the rat could fit, it would have to dig out the nest at least a little bit, leave some trace of evidence behind. But lo and behold, the mammal contracted in its side and squeezed into the hole, no damage and no evidence. Then out it came, baby tody in its mouth. I finally understood why the nests were failing!

Video: During the night, a rat enters the tody cavity and predates one of the two tody chicks inside. The other was presumably trampled based on appearance the next day. This rat was caught on camera for several nights before entering the cavity. (Video by Holly Garrod)

As I continued watching the videos for another nest that had failed, I saw a third culprit appear, one I was surprised I hadn’t seen earlier. Let me introduce you to culprit number three, the mongoose. I watched as the weasel-like mammal appeared and begin excitedly digging at the base of the hole until it managed to disappear inside, and return with a single tody chick in its mouth.

Video: A mongoose digs out the nest from below and enters from the bottom, leaving with a tody chick at the end of the video. No todies were present after checking, suggesting the mongoose likely returned for the second chick. (Video by Holly Garrod)

Mystery solved. Or is it? From the videos and what evidence I could find, it appears that rats are the most wanted, followed by mongoose, and leaving room for both feral cats and dogs. What is clear is that the majority of these predations are from introduced mammals. Even though these mammals have likely been present on the island for several hundred years, it may not have been enough time for the tody to adapt in some way. Throughout these videos I saw no evidence of nest defense behavior, or evidence the parents were even present. Additional behavioral experiments I conducted using a mammal decoy showed the same result—no interest or concern in the “mammal” present at the nest. Do we really know the impact these non-native mammals are having on bird populations? Out of 42 Broad-billed Tody nests I was monitoring, nearly half (20) of them failed, while 6 of 20 Narrow-billed Tody nests failed. All of them appeared to fail from non-native mammalian predators.

While these mammals may not be putting a huge dent on the tody populations, it’s clear they are having an impact. Continued predation could cause a decline in population sizes, especially since the todies show little to no defensive behavior and are therefore highly vulnerable. My research highlights the importance of understanding breeding ecology and the factors that influence nest success in Caribbean endemics like the tody. It’s important to monitor populations so that we can undertake management actions if needed to ensure long-term survival of these amazing birds.

Hugo, George, Irma and Maria: How Hurricanes Reinforce the Bond Between Islanders and Birds

Martha (Mandy) Walsh McGehee recalls her experiences with several devastating hurricanes in the Caribbean during the 1980s and 1990s, and the heartening interactions between people and birds in their aftermath.

I have had hurricane nightmares. Once, they were about boy-named hurricanes. Now they are about the girls. My first “bad dream” was in St. Croix in 1989, when Hurricane Hugo came to visit. My two-story home was demolished. The roof of the top floor and the sea walls on both floors were gone. I was in a downstairs closet for three days – blocked in by debris – before anyone could get to my house in the East End. I was lucky to be on the first flight to the United States. I never returned to St. Croix. Instead, I relocated to the island of Saba in 1990.

On Saba, I had become known as the “Bird Lady” due to my work with the Rare Center for Tropical Bird Conservation (now called RARE), and my experience rehabilitating birds. My doorbell rang often and I would answer it to find an islander with a cardboard box, which contained an injured or dehydrated bird. I lost some, but was able to rehabilitate many.

In 1992 I met a man from Miami who came to Saba without a dive buddy and we eventually married. His experiences in Florida prompted him to update my home for hurricanes. For example, he immediately made certain that the glass doors and windows had adequate permanent shutters. All went well until my second bad dream in 1998: Hurricanes George (followed a year later by Lenny). We retreated to the laundry room that was a level down from the house and protected from the sea by our cistern. When we emerged and went upstairs to the main house, we found the stone walls were intact but the house was full of water. George even took our fireplace chimney and part of the roof with him!

I walked outside to our courtyard and couldn’t believe the number of Purple-throated Caribs and Bananaquits that were waiting on bare twigs near where our feeders had been. We had eight feeders in the fridge that I had removed the evening before George hit, and we took them out immediately.

The first feeder went to a Purple-throated Carib we called Buddy. He dominated the pool area and successfully defended “his” feeder from all other hummingbirds and Bananaquits. His perch was less than a foot away. We always talked to him and it took him no time to recognize his name. If he wasn’t on his perch above the feeder he would come in if we called him. When I removed his empty feeder he would perch outside my front door. When I came out with a full one he would fly to my shoulder and ride to the feeder. I think he chose the shoulder over the feeder to avoid being sloshed with sticky fluid. He was one smart bird!

With Buddy safe it was time to check on our Gray Kingbird named Jeremiah, who we rehabilitated after receiving him as a nestling. We had raised him in our family room, teaching him to catch moths and bugs outside when he was fully feathered and starting to fly. He came immediately when I called. Needless to say, it was such a relief that he had also made it through the Hurricane!

After Hurricane Georges in 1998, the lack of vegetation revealed a sight never before seen from my house- the airport down below. (Photo by Mandy McGehee)

After tending to the birds, I looked around and saw that the elfin forest was completely gone, stripped bare of all leaves, fruits and flowers. I knew what we had to do. We had a satellite phone and called Miami. I managed to get a donation of 250 hummingbird feeders and we ordered four pallets of birdseed to be shipped to the island in the fastest way possible.

The word spread quickly through the island that I had ordered emergency rations for the birds and as a result, our house became a feed and feeder distribution center. Most of the islanders lost their roofs. I can remember blue tarps covering damaged houses everywhere. Yet, in the midst of utter devastation, I would see Sabans out every day filling feeders for the birds.

From my experience, islanders really began to pay attention to their birds after the hurricane. Because the elfin cloud forest was gone, many birds that were primarily seen only there and passage migrants were forced to come halfway down the mountain to the villages in search of food. This excited people and I was constantly identifying birds for curious residents. A Baltimore Oriole was spotted and soon attracted the whole neighborhood!

Much of the vegetation on Saba was damaged after the hurricanes- removing critical food sources for many of the island's birds.

Saba has no standing water, so water birds were especially exciting. One of the most memorable bird identifications I made was of a Green Heron. I arrived at the home of an elderly gentleman who was standing in his yard waiting for me. He thought the bird was the prettiest bird he had ever seen. He wanted to know everything about it. I always had a bird guide in my car so was able to answer all of his questions. After spending over half an hour discussing the bird and looking at it from all the varying angles, I finally told the man I needed to go home. He gave me a big hug and thanked me with tears in his eyes. He said he hoped the bird could go back to its home, but hoped that if another hurricane came the bird would visit again.

I have had nightmares again, since Irma and Maria. Throughout my career, I traveled to many islands to supervise bird projects we were working on in the Lesser Antilles. My heart breaks for all the islands impacted by the recent hurricanes, and I know many of them- and their birds- well. I am hoping that, by telling my story, maybe those islands can plan ahead and have a repository of feeders and seed on hand at the beginning of hurricane season. They will likely be rewarded, as I was, with an island that truly loves and takes care of its birds.

I would now like to add a postscript. Since writing the first draft of this article I have been in almost daily contact with my very dear friend on Saba who is the current bird rehab person specialist. When she wrote to tell me there was no more seed and few feeders on the island, I arranged for her to get in touch with Lisa Sorenson. Lisa has arranged for a seed and feeder shipment to Saba. I will always be grateful to BirdsCaribbean, and I am very proud to be a member.

By Martha (Mandy) Walsh McGehee, biologist and member of BirdsCaribbean since its beginning in 1988.

Editor’s note: We thank Mandy for writing about these memories. Her inspiring story, originally told to Lisa Sorenson by phone after Hurricanes Irma and Maria hit in September 2017, motivated us to make sure that all the islands (15) impacted by these hurricanes received shipments of feeders and seed. We’re happy to report we were able to do this, thanks to many generous donors to our Hurricane Relief Fund. We continue to help birds and our partners recover with many restoration activities planned for 2018. The needs are enormous, however, so continued donations to the fund are welcome.

The Status of Caribbean Forest Endemics—Special Issue of JCO

The Journal of Caribbean Ornithology (JCO) is excited to announce the release of a Special Issue on the Status of Caribbean Forest Endemics (Volume 30, Issue 1). Inside you’ll find a total of 10 publications, 9 of which focus on different forest endemic birds from central Cuba down to Grenada. The tenth publication provides statistical evidence of the JCO’s invaluable role as a multi-lingual, regional scientific journal that outshines other ornithological journals through its distinct subject strengths, especially in terms of papers published on the distribution and abundance of forest endemic species.

Map showing locations of research on various Caribbean forest endemic birds featured in the Special Issue of JCO.

In this Special Issue, we highlight those strengths with a collection of publications specific to forest endemic birds, many of which have become icons and flagship species for their specific island communities. In some cases, there is good news to report, whether it be population growth or range expansion, while in other cases, there are greater causes for concern and subsequent action on our part. The extirpation of the Golden Swallow from Jamaica, for example, is a stark reminder of the vulnerability of some of our forest endemics, and a prime example of the complexities of the problems that island birds face.

As stewards of island bird communities, we know that we must often be two steps ahead when it comes to making informed decisions with local conservation management practices. Islands are filled with diverse fauna and flora that interact in ways that can’t be seen anywhere on the mainland, but simultaneously their populations can often suffer the most from even the smallest disturbances. Our resilience must make up for those species that have such little of it. And here at the JCO we firmly believe that making the most current and impactful research available to our Caribbean community is one of the many critical steps towards doing exactly that.

The following are brief synopses of each publication you’ll find in our Special Issue, which we hope will quickly spark your interest in reading through each in more detail.

Our Special Issue starts off in the forests of Montserrat, a habitat heavily impacted by volcanic activity over the last twenty years. In Bambini et al.’s Current population status of four endemic Caribbean forest birds in Montserrat, current populations of four endemic forest birds are surveyed for, including the Bridled Quail-Dove (Geotrygon mystacea), Forest Thrush (Turdus lherminieri), Brown Trembler (Cinclocerthia ruficauda), and Montserrat Oriole (Icterus oberi).

We move to the Greater Antilles where, in the face of recent extirpations from its former range, Peña et al. bring us in-depth news on the endangered Giant Kingbird’s remaining foothold in Cuba with their publication Distribution and abundance of the Giant Kingbird (Tyrannus cubensis) in eastern Cuba.

Moving westward across the Caribbean’s largest island, we are now presented with information on a newly identified population of Palm Crows that may exceed 200 individuals, thanks to recent work by Maikel Cañizares Morera in his publication Nueva localidad para el Cao Ronco (Corvus palmarum minutus; Aves: Corvidae) en Cuba Central.

To the east, on the island of Puerto Rico, Anadón-Irizarry et al. provide us an invaluable update on the Status and recommendations for the recovery of the Elfin-woods Warbler (Setophaga angelae) in Puerto Rico. In light of devastating impacts to forest habitats by recent hurricanes, this work will be pivotal in helping post-hurricane conservation efforts understand the species’ vulnerability and most pressing needs.

In Haakonsson et al.’s Conservation status of Grand Cayman (Amazona leucocephala caymanensis) and Cayman Brac (Amazona leucocephala hesterna) Parrots, we find ourselves ~250 miles south of Cuba amid the Cayman Islands, where alarmingly two subspecies of Cuban Parrot are being found in fewer, more concentrated population sites.

Our journey swings us back east into the Lesser Antilles to the neighboring islands of St. Lucia and Martinique, where Mortensen et al. report on the Current status of the Endangered White-breasted Thrasher (Ramphocinclus brachyurus), a dry forest songbird endemic to Saint Lucia and Martinique. Heavily geographically restricted on both islands and facing myriad threats, new and amplified life history information on the White-breasted Thrasher reviewed in this publication will undoubtedly prove invaluable for new conservation plans underway.

To the south lies the island of Grenada, where Bonnie L. Rusk has been undertaking Long-term population monitoring of the Critically Endangered Grenada Dove (Leptotila wellsi) on Grenada, West Indies. Here Rusk stresses the current critical state of the Grenada Dove based on long-term population trends and multiple obstacles facing species recovery.

Lastly, we set sail back up towards the Greater Antilles, finding our way to the beautiful island of Jamaica, and in particular its Cockpit Country – a region known for its seemingly impenetrable (yet still vulnerable) geography of karst-limestone hills. Herlitz Davis’ publication on Forest disturbance has negative consequences for the persistence of Jamaica’s threatened and endangered bird species in Cockpit Country brings forth evidence of an association between forest disturbance and bird distribution patterns in a globally important area for bird species that is under pressure from all sides by various types of habitat disturbance.

Pulling back to an island-wide view, Proctor et al.’s time censusing the remote corners of Jamaica for aerial insectivores completes an ongoing effort to determine whether any Jamaican Golden Swallows persist on the island in light of there having been no individuals reported since the 1980’s. The Last search for the Jamaican Golden Swallow (Tachycineta e. euchrysea) confirms the local extinction and highlights the importance of using new knowledge to strengthen conservation plans for the subspecies that persists on the island of Hispaniola to the northeast.

The Special Issue’s final publication is an equally important one in which we are empirically reminded of the unique niche that the JCO fills in the wider world of ornithological publications. The role of a regional journal as a depository for valuable ornithological data as demonstrated by Caribbean forest endemic birds, by Devenish-Nelson et al., is an uplifting report of the impact that our community’s journal is having on birds, people, and the bright future of research and conservation.

You will find the issue in its entirety for free download here:

Thank you to all the authors, reviewers, and members of the production team for making this Special Issue possible. Enjoy, and please spread the word!

BirdsCaribbean Welcomes News of Proposed Jamaican Wildlife Sanctuary

Great Goat Island (foreground) and Little Goat Island.

BirdsCaribbean, the region’s largest conservation organization, warmly welcomes news that the Government of Jamaica is planning to establish a Wildlife Sanctuary at Goat Islands, in the Portland Bight Protected Area (PBPA).

“This is a great Christmas gift to Jamaican and international campaigners, who have advocated in recent years to have Goat Islands protected,” said Lisa Sorenson, Executive Director of BirdsCaribbean. “We wish to congratulate Prime Minister Andrew Holness’ administration for this bold and forward-thinking move.”

Sorenson pointed out that the PBPA was designated an Important Bird Area (IBA) and Key Biodiversity Area (KBA) by BirdLife International. “These are nature’s biodiversity hotspots,” noted Sorenson. “Goat Islands include important and threatened habitats for birds and other species, especially its pristine mangrove systems and dry limestone forest.”

BirdsCaribbean also warmly commended the Jamaica Environment Trust (JET), under the leadership of Diana McCaulay, for its determined advocacy, as well as the Caribbean Coastal Area Management Foundation (C-CAM), supporters and advocates from all walks of life. “Diana McCaulay is a staunch defender of Jamaica’s environment,” said Sorenson. “We wish her all the best in her retirement and look forward to working with JET’s incoming CEO Suzanne Stanley, and with all our Jamaican partners in 2018.”

West Indian Whistling Ducks are a threatened regional endemic, resident in the PBPA. They have been declining in Jamaica due to loss of wetland habitat.

The PBPA, including Goat Islands, is home to 17 endemic birds (found only in Jamaica) and many resident birds, such as the West Indian Whistling Duck – one of the most threatened waterfowl in the Western Hemisphere Endemic species include: Jamaican Lizard Cuckoo, Jamaican Oriole, Jamaican Owl, Jamaican Tody, Sad Flycatcher, Jamaican Spindalis and Jamaican Mango. The area is a critical refuge for numerous neotropical migrants, including ducks, warblers, waterbirds, shorebirds and seabirds, that spend the winter or stop off in the area.

“The Caribbean islands are fragile, and increasingly vulnerable to climate change impacts, as well as human activities such as tourism and housing developments. This has been a very difficult year for Caribbean birds on numerous islands, after two devastating hurricanes. We are delighted by this positive news as the year draws to a close,” said Sorenson.

Forest Restoration in the Dominican Republic: How I Got the Birds to Work for Me

Follow Spencer Schubert on his adventures into remote corners of the Dominican Republic and learn how birds (and their poop!) naturally restore forests. And they do this for free!

Bird enthusiasts have long struggled with the challenge of attracting birds to their backyards, often employing the use of feeders, bird baths, or populating their gardens with plants that birds like. There’s something about birds that really captures our attention, whether it’s their impressive bright plumage or the cheery music they produce.

The Palmchat (Dulus dominicus) is one of the most unique birds in the Caribbean region. The species is endemic to the island of Hispaniola. Over the course of our studies, we have found evidence that Palmchats consume more than 40 species of fruits, making them the most generalist and important seed dispersers known to these landscapes.

But birds have a lot more to offer beyond aesthetics. With an estimated 10,000 species of birds inhabiting our planet, it is perhaps unsurprising that they have adapted to eat just about any type of food found in nature. As it turns out, birds’ choice in cuisine often turns out to be beneficial to environments where humans live. Scavenging vultures limit the spread of pathogens by consuming dead animals. Birds of prey control rodent pests. And many birds feed on insects that can be damaging to farmers’ crops.

Another ecosystem service that fewer people are aware of is the dispersal of seeds in bird feces. That’s right! I am talking about bird poop. But before we all get too excited about bird poop, I need to take a few steps back to properly explain what I mean by this…

Many different kinds of birds have a sweet tooth for the juicy, nutritious fruits of the forest. But do yourself a favor and resist the temptation to try strange fruits that you see birds eating. Many of these are unpleasant and even toxic to people. Our palates are very different from those of birds, and that is no coincidence. Birds have evolved over time in native ecosystems with their plant neighbors, and many plants have adapted to take advantage of birds in a remarkably clever way.

You see, plants are faced with a different set of problems than those facing animals. Most importantly, they can’t really move around. For example, a tree cannot choose where it ends up and where it takes root. Long-lived trees might produce thousands, if not millions of seeds over their lifetime. Most of these fall to the ground directly below their parent, where they either get snatched by insect or rodent predators, fail to germinate, or eventually succumb to the overbearing shadow of their parent. (And you thought your parents were oppressive!).

Some lucky seeds manage to venture away, taking a ride with the wind, through the water, or undamaged in an animal’s gut. Some of these lucky seeds get even luckier still, by landing safely in a nice patch of fertile soil and substrate with moderate lighting from a gap in the forest canopy above.

Birds’ ability to fly long distances and visit a variety of habitats in a relatively short period of time makes them great seed dispersers from the perspective of the plant, and these two groups have evolved a mutualism for which they depend on the other. In exchange for their seed-dispersing services, birds are rewarded with a food supply.

Can a seed, dispersed, create a forest?

For my current research, I am working in the Dominican Republic, where I am trying to collect data to understand how seed dispersal by birds in cattle farms might be important for future forest restoration efforts in the region. Human populations all over the world are ravenous for beef and dairy. And in the tropics, by many estimates, the clearing of forests for livestock grazing lands has historically been the leading cause of deforestation. As a result, many experts see forest restoration in abandoned pastures as a key conservation strategy both in the present and in the future.

Constructing barbed wire fences around isolated trees in pastures allows us to study how birds may contribute to seed dispersal and regeneration patterns on abandoned farms. Some of the different plot types in this experiment included (a) mango trees, (b) open pastures without trees, and (c) Royal Palm trees. (photos by Spencer Schubert)

Having said that, restoration projects are expensive. The costs associated with growing trees in a nursery, transporting them, and caring for them after transplantation are high. It can conceivably cost thousands of dollars to manually reforest an area the size of a basketball court. In regions such as our work site in the Dominican Republic, where economic conditions are such that most working class jobs only pay $10 to $20 dollars per day, it is very difficult to convince organizations to take on these expensive projects.

The first step to my research project began about 18 months ago, when I secured permission to conduct my studies on a single large cattle farm near Jarabacoa, Dominican Republic. The land owner agreed to let me fence off small sections of existing pastures to study seed dispersal and forest regeneration in the absence of human management and grazing, simulating abandoned conditions.

Señor Jose Brache is quite the character. An older gentleman on the verge of retirement, Sr. Brache much prefers his peaceful farm over the hustle and bustle of urban Santo Domingo. Like many older Dominican men, he has a lot to say about just about everything. It has become a frequent occurrence that Sr. Brache will encounter us on the main farm road in his truck and “kidnap” us for a ride to a part of the farm where he will tell a story about what the area looked like when he bought the property more than 20 years ago.

The first part of my project has been to study how certain isolated trees can attract birds to venture away from the forests out into the open pasture and how this might result in increased seed dispersal by birds and forest regrowth. Some of these selected trees included colony nest trees of Hispaniolan Woodpeckers and Palmchats, large mango trees, and control plots with no tree.

Perhaps the more interesting finding has been that relatively little forest regeneration has occurred during the study, so far. Below colony trees with many birds attending the tree, for example, both seeds and tiny seedlings are everywhere, but most of them do not survive. While it is still too early in the study to draw major conclusions, there is plenty of evidence to suggest from this and other similar studies that most seedlings end up losing their battle for survival when facing thick, tall grasses that are typical of these pastures. Furthermore, my findings suggest that it’s not so important how many seeds arrive as how good the habitat is when they get there.

The first step before setting up plots is to locate stands of bamboo and to harvest poles, cut them to specified lengths, and pack them up for transport. (photo by Spencer Schubert)

While isolated trees in pastures are not the miracle cure for deforestation that I would have hoped for, even a small effect is potentially valuable, especially when it’s FREE. These findings rattled my brain… the presence of trees as perches for birds potentially begets more trees and biodiversity. So rather than waiting decades to grow a nice tree that birds will use and disperse seeds around, I thought of a shortcut… Artificial perches.

An artificial perch is exactly what it sounds like: any man made object or structure that birds can perch on. From my reviews of scientific literature, I soon learned that this is not a new idea. A handful of studies dating back to the late 90s have attempted various designs for artificial perches to study how birds use them and contribute to seed dispersal and forest regrowth. Results have been mixed with some more successful than others. There is still not a clear consensus on the subject, but I knew it was worth a shot. I began looking for larger scale restoration projects that would provide an appropriate context to carry out this work.

A New Collaboration with Plan Yaque

Plan Yaque technicians assist Spencer in assembling artificial bird perches. Bamboo grows as a feral exotic plant at many many sites surrounding Jarabacoa. Not only is harvesting bamboo poles for perch materials free, but it also helps to control overgrown stands where it has become invasive. Before burying bamboo perches in the ground, we carefully treat the poles over an open fire to prevent resprouting. (photo by Eduardo Infante Sicard, Plan Yaque Inc.)

I did not have to wait long for an opportunity. It was June of 2016. Through a local colleague, I learned about a budding wetland restoration project in the town of Jarabacoa where I was working that was to be taken on by the NGO known as Plan Yaque. This organization is responsible for the conservation of natural resources in the Rio Yaque del Norte watershed, working mostly in rural farm communities.

After a few probing emails to the director, I was invited to attend an event with this organization. From the way they described it to me, it was meant to be something of a ceremony or convocation of a new community project they were undertaking. Put simply, Plan Yaque had convinced one of the community leaders in a rural neighborhood called Piedra Blanca to let them install a small dam structure in a stream running through the farm of one of the community leaders. They called this dam “trampa de agua” (water trap), and the premise of this project was to create a small reservoir in a headwater, spring-fed stream to maintain human-usable water sources from going completely dry during droughts.

Another major focus of this project is planting native tree species alongside this stream to help establish riparian forests with the aim of preventing soil erosion and mitigating the contaminants in the environment. They labelled the whole project with a clever title: “Litro de Agua” (Liter of Water) to communicate their objective of providing a consistent source of clean water to keep their farms going.

I met up with the director of Plan Yaque and several technicians on a hot June day, and we made our way out to the site riding in flatbed of their pick-up truck along a rural highway through the foothills of the Cordillera Central. Only a day prior, the technicians had finished their makeshift dam, made from a combination of sandbags and old recycled car tires—a clever and low-cost approach for this function. On the near side of the creek, they had enclosed part of the pasture field with a barbed wire fence about 25 meters wide and 60 meters long to keep cattle from disturbing the upper stretch of the stream and their improvised dam construction.

Plan Yaque’s technicians held a short public forum with the family and neighbors explaining the goals of the project and inviting a discussion on how they could improve the project and monitor its success in more meaningful ways. Beforehand, the director had asked that I share my experiences with the farmers and talk about the importance of birds for healthy forests. My Spanish is pretty good. By this point, I had spent a collective eight academic years studying the language and nearly a year’s worth of time working in various Spanish-speaking countries. Dominican farmers don’t see a lot of foreigners, and I could see a lot of curious stares in my direction as I somewhat awkwardly presented, as I now present to you, this idea that birds (and their poop) are protagonists of natural reforestation. If you found my proposition to be a little eccentric, you can imagine how crazy I must have seemed to these people. Nevertheless, I got my message across and it has given my project an opportunity to greatly expand our research efforts.

One of the most remarkable discoveries during these adventures, from my point of view, concerns the Dominican people. Some of the most outspoken conservationists I have met in the country come from its most remote corners of the country. I have spoken to dozens of farmers over the age of 70 who tell me stories of lush green forests covering the hills and how so many birds have practically disappeared since their childhood. Fortunately for me, these individuals have graciously received me and my research project into their community. Together with our partner organization Plan Yaque, we are now incorporating both of our agendas into a single project. While they struggle to improve water availably and quality for farmers, I am recruiting the birds to bring the forest back and restore at least a piece of the glory that was once the tropical forests of Jarabacoa.

With the support of my university, funders, my partner organizations, and local farmers, we have started up a new project to study this untapped potential of fruit-eating birds. Currently our team is halfway complete in our goal of constructing eight plots for the calendar year. We will continue to study these plots over the course of two years with the goal of turning the project over to our local partners and arming them with new cost-effective, bird-friendly techniques for forest restoration.

The Northern Mockingbird is another important seed-dispersing species at our research sites. While most birds only occasionally venture away from the forest into open fields, mockingbirds are quite comfortable doing so.

I owe thanks to a handful of individuals and organizations for their role in making my project so successful. Devoted efforts from project technician Joaris Samuel Gonzalez and field assistants Alex Lascher-Posner, Paris Werner, Kim Shoback, and Tyler Glaser helped get this study off the ground and were invaluable for data collection. Dr. Eric L. Walters of Old Dominion University helped advise the project and has been instrumental in the progression of my ideas and my development as a scientist. My fiancé, Holly Garrod, has helped me hold my life together during graduate school and has also contributed substantially to my research project as she pursues her own graduate research in the Dominican Republic. Local organizations Plan Yaque and Rancho Baiguate have provided key logistic support, without which this work would not have been possible. Furthermore, numerous private land owners have generously received us on their farms to conduct our field studies. This research was funded jointly by the Rufford Small Grant (II) Program, the Sophie Danforth Conservation Award from Roger Williams Park Zoo, and the David S. Lee Fund Grant from BirdsCaribbean.

New Nesting Habitat for the Bahama Oriole and New Opportunities for Young Researchers

The sun was now enough above the horizon that a few rays made it down to the understory of the pine forest. We walked quickly to our next point then began another nine-minute sampling period. About one minute in, we heard the clear crisp song of a Bahama Oriole, about 100 meters to our south. My student Briana noted this information on the data sheet. While waiting, she also recorded details about the habitat and the surrounding vegetation within a 100-meter radius: number of pines – 100+, number of understory palms – 10-20, number of coconut palms – 0, overall habitat – 100% pine forest.

The oriole sang several more times before the point count ended. Just 18 months prior, when we began the Bahama Oriole Project in October 2015, we would have been extremely surprised if we found an oriole in the pine forest. Previous research suggested that the orioles were concentrated in the settlements, especially around coconut palms, which were thought to be their preferred nesting tree. But in 2016, our team had discovered three different pairs of orioles nesting in this very pine forest, several kilometers from the nearest houses, farms or coconut palms. Now we were conducting an exhaustive population estimate to determine whether the orioles were found in just a few areas in the pine forest, or whether they were utilizing many areas of the pine.

We continued to walk along the long-abandoned logging road to the next randomly selected point. As we gained just a few feet in altitude, the pine forest became drier, and the gorgeous understory Key Thatch Palms became shorter and more scattered. I honestly feel ecstatic to be able to work in these vast remote forests, and as we walked along, I asked Briana what she thought of the habitat. She quickly spoke glowingly of the same features that I love so much – the open canopy, the echo of a Bahama Mockingbird song, and the unfamiliar beauty of the understory thatch palms.

This was Briana’s first fieldwork in the tropics, and she was off to a great start. As we walked, I asked her what she wanted to do after she finished college at UMBC. She said that this was exactly the kind of work that she had dreamed about doing – working on a tropical island, studying a critically endangered species, and seeing all these new birds and habitats. She had just finished her sophomore year as a Geography and Environmental Sciences major. Briana is in UMBC’s prestigious Meyerhoff Scholars Program, which is nationally known for its success in increasing underrepresented minority participation in science and technology.

Breeding in the Pine Forest – “Briana’s Nest”

We conducted eight more counts that morning, and we did not hear or see any other orioles during the counts. However, as we continued west toward our meeting point on one of the main logging roads, the land sloped down again and we entered a wet area with many more understory thatch palms (so named because of their local use in roof making). The common species here is the Key Thatch Palm (Leucothrinax morrisii). To me these palms are the most beautiful plants on Andros, and they have intrigued me since my first days on the island. As we walked, suddenly Briana and I both heard a distinctive short “see-you” whistle, which meant a Bahama Oriole was nearby. She pointed as an oriole flew from one low thatch palm to another. Then, a second bird flew in and swooped up to one of the tallest of these understory palms. I whispered excitedly to Briana that maybe there was a nest nearby.

The first bird then entered the same tall thatch palm. There had to be a nest in that tree, so we approached and started looking under each of the hanging dead fronds. There it was: a neat tan palm-fiber basket, hanging protected under one of the dried-up fronds. We christened it “Briana’s Nest” and stepped back to observe the parents – two stunning adult Bahama Orioles. Both the males and females in this species sport a striking jet-black and lemon-yellow plumage. Both sexes also sing, so it is impossible to tell the sexes apart in the field. We observed both parents bringing food to the nest – there were clearly nestlings, but with the nest over seven meters up, we do not yet have the equipment to further investigate their age or number.

The project has now documented seven nests in the pine forest – three in 2016 and four in 2017. But we know nothing about what happens to nests in the pine forest. In 2018, we will conduct two main projects to evaluate breeding in the pine forest. First, Brianna will lead a project quantifying the key characteristics of the nesting trees and surrounding forest. Can the orioles nest in any part of the pine forest, or are there certain types of habitat (perhaps with tall thatch palms for example) that are preferred nesting sites that need to be preserved? Second, one of the Bahamian students will lead the effort to quantify nesting success and determine the greatest threats to nests – rats, cowbirds or feral cats. So far, we have little evidence of cowbirds in the pine forest, but preliminary surveys with trail cameras suggest that feral cats are likely widespread across the island. And arboreal rats could be important nest predators. Which if any of these threats are significant causes of mortality that need to be managed?

A Big, Diverse Field Crew

Soon we were joined by the two other teams that had been doing point counts that morning. One was led by Rick Stanley, a Masters student at the Imperial College London. The other was headed by Scott Johnson, a Bahamas National Trust science officer – who has a wealth of knowledge about the flora and fauna of Andros. We showed everyone the nest we just found, then compared notes from the morning. Rick’s team had also heard one oriole during counts in the pine that morning, and Scott’s team had heard two. The orioles are never common, but they seem to be widespread on the island.

Before leaving we took time to take some shots of the whole 2017 field crew. I look back upon that photo with a great deal of pride and gratitude. Each one of those young researchers has already made important contributions to the project. It is such a privilege to do fieldwork with students every year. For many of the students, this is the first time that they have traveled outside the US – one had never even been on a plane before this trip! The opportunity to introduce these students to the joys (and challenges) of tropical fieldwork is one of the best parts of this project. I am especially excited when my students get to work with BNT’s Scott Johnson and interact with students from the Bahamas.

Our shot of the field crew differs from many group pictures of field biologists or birders because it includes people of many different backgrounds. By drawing on UMBC’s diverse student population, and by working closely with our Bahamian collaborators, we are trying to bring a broader range of backgrounds and perspectives to fieldwork and wildlife conservation. Work throughout the Caribbean demonstrates the kinds of multinational and multiethnic collaboration that will build capacity in our increasingly diverse US population as well as in the island nations that are the focus of BirdsCaribbean.

Hurricane Impacts on Bridled Quail-doves in St. Eustatius

On September 6, 2017, record-breaking Category 5 Hurricane Irma pummeled the northern Lesser Antilles, leaving a trail of destruction in her wake. While St. Eustatius (affectionately known as Statia) was spared extensive infrastructural damage and power was restored to most homes within a few days, forest cover in the Quill National Park did not fare quite so well. Immediately after the storm, defoliation of the vegetation was clearly visible across the dormant volcano, which rises to a maximum height of 600 meters and suffered the brunt of hurricane force winds of up to 150 mph.

When we felt it was safe to go out, our initial exploration of the Quill on September 9 revealed a shocking sight from the crater rim viewpoint at 400 meters. Areas that were once covered in lush evergreen vegetation were barely recognizable. Gone were the majestic Silk Cotton trees that once dominated the canopy; instead we were confronted with an almost bare crater wall covered in once-towering trees that looked like they had been snapped in two by an invisible giant.

Two weeks later, Hurricane Maria passed to the south of St. Eustatius and brought over 100mm of rain but less severe winds. Again, residents of St. Eustatius breathed a sigh of relief, but our thoughts were with those who suffered greatly in Puerto Rico, Saba, St. Maarten, Anguilla, the U.S. and British Virgin Islands, Dominica and other affected islands. Thankfully Maria’s rainfall helped stimulate vegetation regrowth in the Quill. However much of the original canopy was severely damaged, and all fruits, seeds and flowers that normally provided food for wildlife were lost.

Our immediate concern fell to the Bridled Quail-dove (Geotrygon mystacea), an uncommon to rare resident in a few Lesser Antilles islands, the Virgin Islands and Puerto Rico. This West Indian endemic forages for fruits and seeds on the forest floor. Little is known about the population status of this species throughout its range, but it is thought to be declining in the Eastern Caribbean due to loss of habitat and other threats. The Quill is the only habitat on Statia that supports the quail-dove.

In May 2017 we had conducted a population assessment of the dove in connection with a rodent control project that is being facilitated through the Caribbean Netherlands Science Institute (CNSI). Our initial results were encouraging, with an estimated 1,030 quail-doves (standard error [SE] = 275, 95% confidence interval [CI] = 561-1,621) across its local habitat of 440 hectares. This is possibly the highest known density in the region. With baseline data fortuitously in hand, we were very interested to assess the quail-dove’s population size post-hurricane. Thanks to generous persons that donated to BirdsCaribbean’s fundraising appeal, we were able to repeat the survey in early to mid-November, about two months after Hurricane Irma hit.

The survey team (L to R): Frank Rivera-Milan, Hannah Madden, and Kevin Verdel (by Chris Couldridge)

Our team consisted of Dr. Frank Rivera-Milan (population ecologist with the US Fish & Wildlife Service), myself (biologist with CNSI), and Kevin Verdel (student from the University of Utrecht). We conducted 56 transect surveys of 100 meters, and repeated them 2-4 times. This was fewer surveys than the 70 100-meter transects we had conducted in May because some trails were inaccessible due to downed trees. We also used a playback of the Key West Quail-Dove’s call, given that our surveys took place outside the breeding season, in an attempt to elicit a response from any Bridled Quail-Doves in the survey area. Unfortunately the quail-doves did not respond to the playback, which meant that all the detections during November’s surveys were by sight only. The perpendicular distance of the quail-dove from the transect was measured, and the data collected were brought into program Distance to give a total population size.

Our data analysis revealed an estimated population size of 803 Bridled Quail-Doves (SE = 208, 95% CI = 451-1,229) in November. This is a decrease of about 230 birds from the mean population size estimate of 1,030 birds counted in May. Although this is a decline in the population size of ~22% (SE = 8.2%), statistical tests indicate that this decrease is not statistically significant (Z score = 0.66, P value = 0.51). This is the good news.

Measuring distance from transect (by Hannah Madden) — Measuring distance from the transect point to where the dove was sighted (photo by Hannah Madden)

The bad news is that there is very little food available due to severe vegetation damage and we are now entering the dry season (Dec-Apr). This means that already scarce foraging resources will be reduced even further, which will likely result in decreased survival and minimum reproduction in 2018. The quail-doves we observed looked lethargic and did not flush far or fast during surveys. There is a real risk that the population will decline further due to lack of food. For this reason we plan to repeat the surveys again in May 2018, during peak breeding season.

We were glad to see that dry forest vegetation on the outer slopes of the Quill was recovering quickly. Inside the crater, however, approximately 50% of the evergreen seasonal forest that once covered this area has been heavily impacted by Hurricane Irma. It will take a few decades before the vegetation fully recovers. We expect this will have a negative effect not only on the quail-dove but also other bird species that rely on this unique habitat for their survival and reproduction. For example, instead of the usual flocks of Scaly-naped Pigeons (which are now foraging for food in coastal areas), we are now seeing smaller species like Bananaquit, Lesser Antillean Bullfinch, and the migratory Black-whiskered Vireo.

Following our initial surveys in May we were encouraged by the density of Bridled Quail-doves on Statia, the highest known density in the region at the time (although many islands that support the dove have not conducted population assessments). However, we now have some concerns for the species given its very restricted range (only found in the Quill National Park on Statia, at elevations of around 200 meters and above) and the fact that its natural habitat suffered extensive damage in some areas from Hurricane Irma. With food resources in scarce supply, competition between the doves and other species, such as the more aggressive and widespread Pearly-eyed Thrasher, could lead to a further decline in the already vulnerable population. We recommend removing predators and domestic animals above 250m to help the species recover and enhance its prospects for long-term survival in Statia.

Irma provided us with a unique opportunity to study the impacts of hurricanes on avian fauna on Statia (and elsewhere in the region). It is a bittersweet privilege to be able to contribute our results to the scientific community. Unfortunately, the frequency and intensity of Caribbean hurricanes are predicted to increase under human-induced global warming. We must do all we can to protect and enhance the integrity of our natural areas to help our birds and other wildlife survive the next hit, and hope to come out unscathed on the other side.

We are grateful to BirdsCaribbean for funding Dr. Rivera’s travel expenses, to St. Eustatius National Parks for allowing us to conduct surveys in the Quill National Park, and to CNSI for facilitating this ongoing project. We look forward to reporting back to the Birdscaribbean community after we complete our second post-hurricane Bridled Quail-dove survey in May 2018.

Meet the Superspecies of Parrots: Yellow-crowned Amazon (Amazona ochrocephala)

Many comic book characters we know and love today can be identified by their signature symbols. In the blink of an eye we can recognize the S of Superman’s shield or the beaming light of the Batman logo when Gotham City needs the Dark Knight to fight its villains. Likewise, when many Trinidadians see a parrot with bright yellow on the head they immediately identify it using the local name, “Venez” Parrot. But few people know that this bird belongs to a superspecies group of Amazon Parrots (genus Amazona) comprising 11 subspecies. A superspecies is a species complex of closely related, very similar species that are often difficult to distinguish. The subspecies are categorized into three groups: 1) Yellow-crowned or ochrocephala 2) Yellow-naped or auropalliata and 3) Yellow-headed or oratrix.

Amazona ochrocephala ochrocephala, the Yellow-crowned Parrot, known locally as the Yellow-crowned Amazon (or Venez Parrot) found on Trinidad belongs to the – you guessed it – “Ochrocephala” group. It was possibly introduced from Venezuela or Guyana but its distribution extends into Colombia, Brazil, Suriname and French Guiana. This medium-sized Amazon weighs about 500 grams with primarily green plumage, a yellow forecrown and white eye-ring. Look carefully and you will see that the bend of the wing and base of the tail are both red. These traits are used to distinguish it from the ever present and ever noisy Orange-winged Parrots (Amazona amazonica). If you can’t get an up-close look at the parrot listen for its call which is a distinctive mellow, rolling bow-wow; this is in contrast to the shrill kik-kik…kik-kik calls of the Orange-winged Parrots.

Like most other parrots, Yellow-crowned Amazons are monogamous and prefer to nest in hollow trees or palms. While other Amazons choose their nesting cavities based on tree species, cavity height from the ground and cavity entrance size, Yellow-crowned Amazons tend not to have a preference for a specific tree species but do require trees in good condition. Because pairs maintain their nesting territories throughout the year, things can get really loud if a bird or pair tries to take over another pair’s nest or even if a neighbour oversteps his boundary. Yellow-crowned Amazons are very aggressive and coordinated in defending their nests. The nesting pair will vocalize while perched next to each other or physically attack an intruder by lunging with beak open and wings extended.

If Yellow-crowned Parrots and their superspecies are superheroes of the bird world, then poaching of juveniles can be considered the population’s kryptonite. Fledglings over 40 days old are commonly taken from the wild though some poachers remove nestlings from the cavity when they are as young as three days old. Removing young birds from the wild is as bad for the population as it is for the individual birds. The young parrots are taken before they have reached sexual maturity and therefore, the current breeding pool of adults is not being expanded or replaced.

One reason Yellow-crowned Amazons are so popular for the pet trade is their ability to mimic human speech quickly. Because they are so desirable, some poachers in Central America dye the forecrown feathers of Red-lored Amazons (A. autumnalis) and Brown-throated Parakeets (Aratinnga pertinax) yellow and sell them as Yellow-crowneds to unsuspecting customers. Currently, Yellow-crowned Parrots are considered Least Concern by IUCN due to their wide geographic distribution and estimated healthy population size. However, the combination of habitat loss, their low reproductive rate, and poaching for the pet trade remains a major concern.

Vocalizations: an unsung hero

Even I would admit that hearing a parrot “talk” is very entertaining and amusing. However in the wild they use their own dialect with each other and their communication is not limited to repeating the calls of one or a few parrots. Yellow-crowned Amazons use syntax to arrange the structure of calls including those used in territorial disputes. It is plausible that by using syntax, communication among parrots is more flexible than we think. In addition, dialect through duets is used to woo potential mates and successfully reproduce. Males and females have sex-specific notes. These serve to tell the caller’s sex, availability to pair (i.e., spoken for or not) and to facilitate communication with multiple interested parrots . Yes, all is fair in love and war, even for parrots.

Other vocalizations, like contact calls, are used to maintain order within flocks to achieve common goals such as finding food or avoiding predators. Just imagine how little justice would get served if the members of the Justice League were unable to create a strategy to fight their enemies because they didn’t understand each other! Interestingly contact calls may also serve to ascertain a parrot’s regional identity. A survey of 16 Amazon roosting sites in North and South Costa Rica, 18 miles apart, revealed that each region had a distinct type of call. Researchers found that neighbouring roosts within a region shared a common call type and in each roost a single call type was recorded resulting in the mosaic pattern typical of vocal dialects in humans.

When Yellow-crowned Amazons are kept as pets and taught to repeat silly phrases, we undermine so much of their intelligence and even their identity. Out of the cage they speak their own language, one that takes years to develop and runs much deeper than “Hello” or “Who’s a pretty bird?” In order for this beautiful, complex superspecies to thrive in the wild, we all need to be local superheroes and take a stand against wildlife poaching.

How can you help parrots in the wild?

The Blue and Gold Project recently launched their fundraising campaign to protect the Blue and Gold Macaw in Trinidad. This large, charismatic bird was extirpated from the island in the 1960s. A reintroduction program began in 1999, and after several releases, there is a small, stable population with documented breeding success. The Blue and Gold Project is raising funds to host local capacity building workshops to educate community members about wild macaws and the pet trade, monitor the illegal trade of macaws, and conduct much-needed research on the wild reintroduced population. Please donate today!

Aliya Hosein is a 2017 CLiC (Conservation Leadership in the Caribbean) Fellow working on a Blue and Gold Macaw Conservation Project on her home island of Trinidad. She believes that parrots are so colourful and boisterous that without them forests, savannas and swamps would be dull.

Bird Dispatches from the Hurricane Front Lines

It has been an exhausting few weeks for many of BirdsCaribbean’s partners across the region. The hurricane season is not over for another two months, but Caribbean conservationists are hoping for a break. BirdsCaribbean and its wonderful supporters across the region are doing their best to keep up with a variety of urgent needs, from shipping hummingbird feeders for starving birds to organizing assessments and surveys. There is a lot of work to be done, but teamwork and partnerships are making the difference.

We at BirdsCaribbean extend our heartfelt thanks to all those who have donated towards the crowdfunding campaign so far. Your support means so much to us, as we try to help all our dedicated and hard-working partners get back on their feet after this unprecedented series of disasters. We assure you that the funds will be put to good use, and we will never forget the outpouring of kindness and generosity from folks near and far. It is quite humbling!

Time has passed slowly since the passage of Irma and Maria, and we have been extremely anxious for news from the islands most badly affected. Here are some updates on the bird populations. It is a very mixed picture, so far, so be prepared for good news, but some “not so good”:

BARBUDA

During their visit to the devastated island of Barbuda on September 22, the Environmental Awareness Group’s Andrea Otto and Junior Prosper were thrilled to count eight endemic Barbuda Warblers that had miraculously survived the fierce onslaught of Hurricane Irma – alongside Yellow Warblers. BirdsCaribbean is assisting with intensive surveys in mid-October to assess the population size and actions that can be taken in the short and long term to help the bird.

At Codrington Lagoon – home to the largest colony of Magnificent Frigatebirds in the Caribbean – the team was stunned, however, to find just one small group of 30 adult birds perched on a dead mangrove bush, instead of the usual thriving colony of 4,000 and 5,000 birds in the Sanctuary. The Antiguan team counted about 325 birds soaring in the air above the lagoon. We don’t know yet what has happened to all the other birds. Known as “Weather Birds,” frigatebirds will fly out before the storm hits, so hopefully they are still alive. There were juveniles in the colony not yet able to fly, however. They are known to climb deep into the mangroves and wait out storms, however, no young birds have been spotted. They most likely perished in the storm.

Otto described the Red Mangrove habitat of the lagoon as “burnt”—there was almost no remaining foliage. “Normally, the mangroves are so dense, lush and green that you have to crane your neck to see between and beyond them, and they are loaded with birds,” said Otto. “Now we could easily see for long distances into the sanctuary.” The trees that remained were shorter and stripped bare. The Barbudans with the team said they “barely recognized the landscape.”

The recovery of the lagoon’s mangroves is of grave concern. The Magnificent Frigatebird, considered one of the most threatened seabirds in the Caribbean, depends on mangroves to nest and roost at night. The sanctuary, which is well managed by the local community and patrolled by wardens, provides critical habitat for this species. It also provides sustainable livelihoods for local bird and nature guides that take people into the sanctuary by boat to witness the spectacular site and sound of frigatebird courtship—males puffing out their red neck pouches and drumming on them to attract a mate.

On Barbuda, the team found most large trees had been uprooted or broken. Trees and shrubs had no green or live leaves and there was “not even grass,” reported Junior Prosper. In other wetland areas on Barbuda, Willets, Brown Pelicans, Green Herons, Lesser Yellowlegs and Spotted Sandpipers, as well as Eurasian Collared Dove and a few Pearly-eyed Thrashers were seen. However, no West Indian Whistling-Ducks, a threatened regional endemic were spotted. An intensive survey effort will take place over the next several weeks.

What are the Barbuda Warbler’s prospects for survival? As with many other species on all the islands, this post-hurricane period is a critical time for the birds, because of the shortage of food. “My fear now is that with vegetation largely stripped of leaves, as photos indicate, insect food will be very hard to come by in the coming weeks. I fear more birds may be lost from food shortage post-hurricane than in the storm itself,” observes Tony Diamond (University of New Brunswick), who together with his graduate students has studied the warbler and frigatebirds. BirdsCaribbean will be working with EAG to look at habitat restoration actions that can be taken for the warbler and the frigatebirds.

In the sister island of Antigua, hummingbirds were “highly stressed” after the storms, according to Facebook posts. The Purple-throated Carib descended from upland forests to feed around towns and homes. In their normal habitats, flowers, fruits and insects are gone, and they have also lost secure space and even other members of their species, it was noted.

BAHAMAS

In the Bahamas, which fortunately did not bear the full brunt of the storms on all its many scattered islands – bird species appear to have been moving around quite a bit. The Bahamas National Trust (BNT), a key BirdsCaribbean partner, is on the lookout for Cuban Parrots (Bahama subspecies), which have been “conspicuously absent” from the eastern end of New Providence since Hurricane Irma. They may have moved temporarily elsewhere. “Those of us who live in the East have missed their early morning calls during their flyovers,” our BNT friends report. BNT Warden Randolph Burrows spotted over 100 parrots on the island of Great Inagua, which was hit hard by Hurricane Irma. Residents were also delighted to welcome thousands of American Flamingos on September 14, following the passage of the hurricane. Inagua is home to a breeding colony of 50,000 flamingoes, but there is a question as to whether some of these birds may have been refugees from Cuba and the Dominican Republic. BNT Executive Director Eric Carey, while happy to see the birds, observed: “Hurricanes such as Irma actually make us realize how much we do not know about our flamingos.”

CUBA

As for updates from our hard-working friends in Cuba, due to communication problems, we have received no further updates on the flamingo populations from the first report that thousands were killed in the storm. Nor have we learned how other endemic and rare species have fared such as the Zapata Sparrow and Zapata Wren. The photos show, however, that habitats on the northern coast and cays were severely damaged with many mangroves and other trees uprooted and stripped of vegetation as in Barbuda. We will report as soon as we receive news, which we hope will be positive!

DOMINICA

The eye of Hurricane Maria passed directly over the tiny island of Dominica, which is still reeling from the impact. The port is not yet fully functional for ships. The normally lush, green country, known as the “nature isle” for its stunning and majestic mountainous landscape is barren and brown at the moment. Stephen Durand reported that the devastation is heartbreaking and they are taking it one day at a time. The Forestry Office was severely damaged by the storm and all of its equipment looted. Several of our partners have lost their homes and there is a shortage of food and water in small, remote communities. Communications remain poor due to the mountainous terrain and the extent of damage to infrastructure, although aid is starting to come in via helicopter. Here there is great concern for the two endemic parrots – in particular the Critically Endangered Imperial Parrot (“Sisserou”)—only 400 of these are known to exist in the wild, with none breeding in captivity.

Lennox Honeychurch reported that he has seen some Red-necked Parrots (“Jaco”) flying around, even down to the coast…clearly disoriented, landing in the road looking for scraps of food. So they at least have survived. The fate of the Sisserou is as yet unknown. No one he has spoken to, even in the Carib territory, have seen any since Maria struck. Durand reports that a search for the Sisserou will begin today – we will share news as soon as it is available. While captive birds have survived, they also need food; a BirdsCaribbean member has taken over a small amount of parrot food, as well as bird feeders and powdered nectar for the hummingbird population.

GUADELOUPE

The island of Guadeloupe did not escape the wrath of the storms, receiving blows from both Irma and Maria and causing much damage to parks and protected areas. During an early survey on September 20, Anthony Levesque noted that the swamp areas were completely flooded. Just a few shorebirds were seen, including Great Egret, Semipalmated Plover, Ruff, Least Sandpiper, White-Rumped Sandpiper, Greater and Lesser Yellowlegs, and also two Belted Kingfishers. The following morning, a Green-Throated Carib was seen “fighting against the wind…” Since then, more shorebird sightings have been recorded.

ST. EUSTATIUS

Although not badly impacted by the hurricanes, the small island of St. Eustatius (aka “Statia”) nevertheless suffered damage to many trees on the island and in the Quill/ Boven National Park, which includes the slopes of their dormant volcano, known as “The Quill.” The impacts on wildlife and ecosystems are not yet known. Hannah Madden is concerned about the impact on the endemic Bridled Quail-Dove population that she has been monitoring. BirdsCaribbean will fund an intensive survey of the dove next month. Hannah reports that they received some surprise visitors: A small flock of American Golden Plovers. This species has never been recorded on Statia before; they were likely blown off course by the hurricanes. Partners in other islands are also reporting vagrants and new species showing up – blown in or off course during migration from the hurricanes.

SINT MAARTEN

In Sint Maarten, conservationist Binkie van Es – who was himself made homeless by Hurricane Irma – reported that hummingbirds were of greatest concern, because of the lack of food. Binkie is excited to receive a shipment of 300 hummingbird feeders, on its way from BirdsCaribbean to Sint Maarten/St. Martin. These will be distributed to schools and homes across the island, with the assistance of Les Fruits de Mer and Environmental Protection in the Caribbean (EPIC). “I am afraid we lost half of our Brown Pelican population,” Binkie noted, while observing that White-cheeked Pintails appeared undisturbed. Barn Swallows, he noted, appeared to be displaced from their usual locations. Meanwhile, American Kestrels were finding happy hunting grounds, since the trees and bushes were stripped of leaves. Binkie notes: “Most regular shrubs and trees are sprouting already, but all mangroves took a terrible hit.” The mangrove habitats may take much longer to recover.

ST. MARTIN

On the French side of the island, St. Martin, there was also huge damage to homes and infrastructure. Our partner organization, Les Fruits de Mer, also lost its museum building; fortunately, the contents were packed in a container for removal, so are safe. BirdsCaribbean’s Mark Yokoyama reports that he used ten pounds of sugar in two weeks, as hummingbird feeders he has set up are besieged with birds, including many Bananaquits, Green-throated Caribs, Antillean Crested Hummingbirds and others. Despite the storms’ impact, “hillsides are starting to green up,” our partners report and a few flowers (oleanders) are now blooming. EPIC reports that it will have a renewed focus and will be seeking funds for mangrove restoration in October; BirdsCaribbean will be assisting with these funds.

BRITISH VIRGIN ISLANDS

As vegetation recovers, hummingbird feeders such as this one at a residence in BVI are critical for bird survival.

The British Virgin Islands were hard hit by both storms. Trees were stripped of leaves and many larger trees damaged or destroyed. The largest mangrove forest at Paraquita Bay was completely leafless. Elsewhere, small pockets of mangrove were already removed during the post-hurricane cleanup. This raises a general concern that the destruction of bird habitats, especially forested areas (already threatened in many places by development) may be accelerated by post-storm cleanups. A gas station may be built in their place, rather than the habitat being restored and replanted. “As usual, we try to save what’s left…” was the comment from Birdscaribbean member, Clive Petrovich, on Tortola – who also brought sad news that Bananaquit nests with eggs or young around his home were destroyed by the hurricanes, along with the foliage. He saw a few Bananaquits, and Pearly-Eyed Thrashers, Scaly-naped Pigeons, Kingbirds, Smooth-billed Anis and a few other species were spotted.

There are concerns here too for the hummingbird populations; some have been observed eating arthropods to survive. While bird numbers on Tortola have dropped dramatically, a number of trees (mahogany, sago palms) already have new leaves. Our partners in both the British and US Virgin Islands, which suffered similar devastation, are looking forward to receiving hummingbird feeders from BirdsCaribbean to help these nectar feeders survive during this period of severe food shortages.

PUERTO RICO

We are anxious to hear from our friends in Puerto Rico, and stand ready to assist in any way we can when communications are restored and their needs are established. Of particular concern is the Critically Endangered Puerto Rican Parrot. Reduced population size due to hunting and capture for the pet trade, combined with habitat loss and fragmentation, make this species especially vulnerable to large scale natural disasters. Also of concern is the fate of a number of endemic species in PR following the storm, such as the Endangered Yellow-shouldered Blackbird, Critically Endangered Puerto Rican Nightjar and Vulnerable Elfin-woods Warbler.

What is BirdsCaribbean’s focus in the near and medium term following these terrible storms?

At the moment we are organizing shipments of hundreds of hummingbird feeders and bird seed to our partners on all the islands that have been impacted; several shipments are en route! We will be helping to fund post-hurricane surveys of Bridled Quail-doves in Statia this fall, and also the intensive surveys of the Barbuda Warbler and Magnificent Frigatebird that will take place in mid-October. We will be helping the Forestry Dept in Dominica to replace all their bird monitoring field equipment, including binoculars, spotting scopes, GPS units, backpacks, cameras, and more. We have also been topping up cell phones for our partners so that they can communicate, and anticipate that we will funding mangrove and habitat restoration projects.

Again, we are truly thankful to all that have donated so generously to our ongoing fundraising effort for hurricane relief for our partners and beloved birds that has allowed us to help with recovery actions. We particularly wish our partner Vermont Center for Ecostudies and Kevin Loughlin of Wildside Nature Tours, who are supporting us with a GoFundMe site of their own (please donate as all funds raised up to $10K are matched by Wildside!).

This has been an extremely difficult time for BirdsCaribbean partners, for the birds – and for the people of the Caribbean. However, the islands are resilient, and we are confident that, while it will be slow, a steady recovery is underway. In fact, as each day passes, the region is slowly getting back on its feet. We plan to bring further bird updates as more reports roll in! Stay tuned.

Good News! Conservationists Excited to Find Surviving Barbuda Warblers on Devastated Island

Warbler found! The first Barbuda Warbler spotted by Andrea Otto and Joseph Prosper of the Environmental Awareness Group on their survey trip to Barbuda on Sept. 22nd. No warblers were seen on the first survey trip to the island on Sept. 15th. (Photo by Andrea Otto.)

On Wednesday, September 6, Hurricane Irma engulfed the tiny Caribbean island of Barbuda with 185 mph winds, leaving most of the population homeless and a landscape ravaged by wind and surging waves.

Since the storm passed, the Caribbean birding community has been increasingly anxious about one bird in particular: the endemic Barbuda Warbler, a Near Threatened Species. Had this charming little bird survived the storm?

Well, at last there is some good news. BirdsCaribbean is delighted to report that, during a one-day survey trip to Barbuda on September 22, a team from its Antiguan partner Environment Awareness Group (EAG) and the Department of the Environment discovered a total of eight Barbuda Warblers.

As the only endemic species on the island and country of Antigua and Barbuda, the Barbuda Warbler has a special place in the small community’s hearts. The bird has a perky posture and constantly flits around, searching for insects in trees, thorny scrub and coastal areas. Its estimated population is between 1,000 and 2,500, but before the hurricane its population trends were not determined.

The first bird was spotted by EAG’s Andrea Otto and colleague Junior Prosper in a fallen acacia tree. “I saw a flash of grey…” Otto reports. “I whispered to Junior – it’s a Barbuda Warbler!” They managed to get a good view and confirmation of the smart little warbler’s grey and yellow plumage. After that, “It took us a while to get a clear photograph of the bird as irrefutable proof of its survival,” notes Otto. The team recorded the birds in a relatively small area near the secondary school in Codrington, the main settlement on the island.

BirdsCaribbean is supporting the EAG and Department of Environment to conduct bird and wildlife surveys over the next five weeks. They are helping the team design a survey plan that will cover the habitat on the island and provide an estimate of the warbler’s population size. Ornithologists and other skilled birders in the region and beyond will assist with an intensive survey effort in the coming weeks and months. The team will also devise a plan to help the Barbuda Warbler and other wildlife on the island recover, such as replanting native trees and mangroves that were destroyed in the hurricane.

Editor’s Note: BirdsCaribbean has launched a fundraising effort for hurricane relief for our Caribbean partners and birds. All the funds will be distributed to bird conservation partners across the Greater and Lesser Antilles islands to help them get back on their feet and replace what was lost in the storm—from notebooks, materials and binoculars to offices and infrastructure. The Fund will also support field surveys to assess the status of endemic, resident and many migrant species, as well as recovery and habitat rehabilitation actions by our partners, such as planting native trees that feed birds and provide habitat. Sincere thanks to those that have donated already!

After the Storm

Take care of yourselves and, once you and your loved ones are safe, remember our birds and consider their plight.

There is no doubt that the landscape on some islands has already changed, perhaps irreversibly so, after the passage of the strongest hurricane on record in the Caribbean. The Codrington Lagoon on Barbuda, for example – a beautifully preserved RAMSAR site – is home to the largest colony of Magnificent Frigatebirds in the region (around 2,500 pairs). It was breached during the storm and the sea has flowed in. Barbuda itself is now a scene of devastation, with almost all buildings damaged or destroyed and most inhabitants evacuated. So, what of the endemic Barbuda Warbler, a small bird that is Near Threatened (likely less than 2,000 individuals) – did it survive?

Moreover, human activity is already contributing to the changing island landscape on a perhaps unprecedented level. Barbuda itself is the proposed site of a tourism development that has already triggered controversy because of its possible impact on its fragile environment. Other large tourism and housing developments, mining and other industrial activities and urbanization are all threatening bird habitats across the region. The unchecked over-development of the Houston area, which replaced wetlands and woodlands with concrete was a major contributing factor to the excessive flooding.

While discussion and research into the impact of climate change on tropical weather patterns (in particular, the link to hurricanes) continues, issues such as rising sea levels and warming seas are becoming increasingly evident in the Caribbean. All of these factors combined increase the chance that a single event like Hurricane Irma may cause a species, such as the Barbuda Warbler to go extinct.

Last year, we recorded the devastating impact of Hurricane Matthew on birds in the Bahamas and Haiti, in particular. We also noted that some species “bounce back” more quickly than others. After the storm passes, those birds that survive face long-term problems. In the path of the storm, trees and shrubs lose all their leaves, buds, flowers and fruits. Trees (often the older, larger trees that provide food and shelter) may be uprooted. Riverbanks are scoured and whole neighborhoods transformed. In hills and mountains, there is the threat of landslides. Damage to reefs and seagrass beds may decrease marine productivity. Nesting beaches may be washed away. Birds may lose their nests, shelter and food. Others get displaced to new areas, where they may not thrive.

What happens to birds in a hurricane?

The flamingos had taken shelter in the mangrove vegetation. (Photo by Casper Burrows)

We know that many species can respond to the indicators that a storm is nearby, such as a drop in barometric pressure, changes in temperature, rainfall and light. In some species these changes trigger them to change location. The Bahamas National Trust notes that its flamingoes, for example, will fly away ahead of a storm and some seabirds on the wing will increase their altitude to try to get above the storm. Many other species respond to threats by trying to hunker down in safe places. Migratory birds may change their plans, and depart earlier than usual. Some very brave Whimbrels have even been recorded flying directly into a storm – for example, one named Chinquapin, braved Hurricane Irene in 2011. Read more here.

During and just after the passage of Hurricane Irma, Bahamian flamingoes were spotted, sheltered by coastal forest and mangroves, in storm conditions on the island of Great Inagua; and Cuban Parrots (Bahamas subspecies) were seen feeding on guinep fruit off the trees, which had somehow managed to retain its fruits. Some birds are true survivors, but with such a large and powerful storm as Irma, nowhere is entirely safe. Evidence is just now coming to light that many birds were killed outright during the storm, including thousands of flamingos in the Cayo Coco Cays of Cuba. Juvenile birds will fare worse than the adults. Often the impacts – on breeding cycles, for example – are indirect and more long term.

In 1998, Hurricane Gilbert displaced Black-billed Streamertail hummingbirds about 35 miles east from the dense wet limestone forests of eastern Jamaica to Kingston. A kind citizen found many of these streamertails on her veranda, weak and hardly able to fly. She went from putting out two or three small bottles of sugar water to supplying more than 2 gallons a day. Her efforts undoubtedly saved hundreds of birds.

What can we do to help birds after a hurricane?

It may take weeks, months or decades for our forests, wetlands and gardens to return to their former glory. In the meantime, you can do a lot to help your local birds.

Remember the birds as you stock up with supplies, and maintain your hummingbird and seed feeders and bird baths.
Provide food for birds following the storm. Feeding birds does not require expensive feeders or equipment.
- Seeds. Many pigeons and doves will eat cracked corn and small seed-eaters will take cracked rice. Watch out for changes in bird behaviour which may indicate food shortages. For example, White-crowned Pigeons may suddenly start feeding on the ground. If you see this, put out food in suitable places (ideally where birds are not vulnerable to cats).
- Sugar water. You can make a hummingbird feeder from a bottle with a screw on cap by piercing a small hole in the cap. Fill it with sugar water (1 part sugar to 4 parts water). Use some wire to suspend the bottle at an angle in a place where hummingbirds will find it. You may need to put something red on the bottle to attract the birds initially.
- Fruit. To provide fruit for birds, use a horizontal stake with 2 inch nails driven into it to put out left over fruit skins for birds.

What else can we do?

We need to document the impacts of hurricanes on birds so that we can determine which species have been affected and what we can do to help them. As soon as you can after the storm, take photographs and videos or take notes about:

the extent of damage to habitats (and the process of recovery);
observations of unusual behaviour by familiar birds;
observations of threatened or rare species in their habitat (that might indicate that they survived);
observations of dead birds; and
observations of unusual birds that may have been blown into your area by the storm ( see also http://birdcast.info/forecast/hurricane-irmas-impact-on-birds/).

Please also enter your observations into eBird Caribbean. You may also post your photos and observations on the BirdsCaribbean Facebook page, twitter (@BirdsCaribbean) and BirdsCaribbean Listserv (or send to Lisa.Sorenson@BirdsCaribbean.org).

Note that because birds may travel to or get blown off course to other islands during storms and hurricanes, it’s just as important to survey birds in other islands that were NOT affected. For example, the more southern Lesser Antillean islands (Grenada, St. Lucia and St. Vincent and the Grenadines) may serve as a refuge from hurricane events. Please go out and do some surveys and keep an eye out for different birds and vagrants in your islands!

Donate to help our Caribbean partners and birds recover

BirdsCaribbean has launched a fundraising effort for hurricane relief for our Caribbean partners and birds. All the funds will be distributed to bird conservation partners across the Greater and Lesser Antilles islands to help them get back on their feet and replace what was lost in the storm—from notebooks, materials and binoculars to offices and infrastructure. The Fund will also support field surveys to assess the status of endemic, resident and many migrant species, as well as recovery and habitat rehabilitation actions by our partners, such as planting native trees that feed birds and provide habitat. Sincere thanks to those that have donated already!

In the long-term

We need to take the opportunity to remind our policy-makers of the importance of maintaining and protecting our natural areas, and to continue public education among stakeholders. Intact mangroves provide the most effective protection from storm surge for coastal settlements and infrastructure. Wetlands soak up and store excess rain and protect surrounding areas and property from flooding. Forests prevent land slippage and flash flooding. Caribbean residents – whether town dwellers, farmers or fishermen – are seeing this for themselves in their daily lives.

Hurricane Irma will perhaps serve as a reminder that the delicate balance of our widely varied ecosystems is in jeopardy. As the University of Oklahoma’s Jeremy D. Ross notes in his September 9 article, if we do not maintain a healthy natural environment, “We stand to lose not just an isolated songbird most people have never heard of, but potentially the vibrancy of entire ecosystems that provide the Caribbean its inherent allure.”

Celebrate World Shorebirds Day 2017 and join the Global Shorebird Count!

World Shorebirds Day logo featuring a Ruddy Turnstone.

World Shorebirds Day, September 6th, is right around the corner. According to the founder of this annual event, Gyorgy Szimuly, “World Shorebirds Day is a special day to celebrate shorebirds and the hard-working people dedicated to saving them.” Since it’s inception four years ago, the event has received a wonderful response with people from all over the planet joining together to enjoy shorebirds and promote their conservation.

One of the main activities of World Shorebirds Day is the Global Shorebird Count—hundreds of enthusiasts, including birdwatchers, educators, conservationists, researchers, politicians, and even hunters, will take part between 1-7 September. “The Caribbean region has been a great supporter since the beginning,” commented Gyorgy. “We hope that people from many different islands plan an event and again participate in the count. It would be fantastic to hit an all-time high in the number of registered sites in 2017!”

Registration is open and available at this link. For committed and returning counters there is even a Loyalty Program – read about it on the blog. Everyone is encouraged to register through the form on this page and have a chance to win one of the fantastic prizes.

You never know what exciting new birds you might see on World Shorebirds Day. For example, last year Ann Sutton spotted the first Piping Plover ever seen in Jamaica on Pedro Pond! All observations are valuable, however. Many shorebird species are declining and we still know very little about shorebird migration in the Caribbean, such as where birds are stopping to rest and feed on migration and numbers of each species. So be sure to head out and find some shorebirds for World Shorebirds Day and enter your checklists for your Global Shorebird Count in eBird Caribbean. If you’re new to eBird, check out this Quick Start guide.

To make your submitted data visible to World Shorebirds Day, please be sure to share your checklist with worldshorebirdsday eBird username of World Shorebirds Day (WorldShorebirdsDay) or add shorebirdsday@gmail.com email address, to your contact list, and share all your related checklists with us (only checklists made during the World Shorebirds Day count period between 1–7 September 2017 are eligible). Guidelines for sharing checklists are here.

Don’t forget also that any counts carried out at a wetland or beach count as a Caribbean Waterbird Census (CWC) count; enter your data as a CWC count on step 2 of data entry on eBird Caribbean. In addition, your shorebird count can be part of the International Shorebird Survey, which we are just beginning to encourage in the Caribbean – read more here.

Hat’s off to our partner in Puerto Rico, Sociedad Ornitológica Puertorriqueña (SOPI), who are going all out this year with their World Shorebirds Day celebration. They have organized the 1st Shorebird Festival—a 3-day event from September 1-3. A variety of exciting activities are planned including educational talks, shorebird identification workshops, activities for children, live music, shorebird artwork, and a photographic exhibition of shorebirds presented by local photographers. According to organizer Luis Ramos, “We want to educate the community about the great variety of shorebirds that migrate to the island and promote the conservation and restoration of habitats for them.” If you live in Puerto Rico, be sure to participate!

Good luck to SOPI on their festival! And we look forward to hearing back from many of you about your findings on World Shorebirds Day!

Saving a Species in Peril—A Holistic Approach to Conserving the Ridgway’s Hawk in the Dominican Republic

Soaring above the tree tops of Los Haitises National Park is the mighty Ridgway’s Hawk. Conflicts with humans and changes in its forest habitat have made it hard for this species to survive. Marta Curti tells us about the work of The Peregrine Fund to save this critically endangered raptor.

The Ridgway’s Hawk is endemic to the Caribbean island of Hispaniola, but is now considered to be extinct in Haiti. The last remaining population of this species is in a small national park, Los Haitises, in the Dominican Republic (DR). There are only an estimated 350-450 individuals left in the wild.

I have been working as a biologist for The Peregrine Fund for the past 17 years. I have been lucky enough to have been a part of several of their projects helping to conserve birds of prey in many countries around the world. In 2011, I joined the team working in DR to help to save the Ridgway’s Hawk from extinction.

The Peregrine Fund’s Ridgway’s Hawk conservation project has been running since 2002 and has many facets. When I was asked to share a short article about our project on the BirdsCaribbean blog, I spent a long time thinking what to write about. I could focus on the advances we have made to prevent botfly (Philornis pici) infestations in nestling Ridgway’s Hawks – an issue that, if left untreated, could cause over 70% mortality in young hawks.

Or I could discuss the successes of our Assisted Dispersal Program: bringing young hawks from Los Haitises National Park and releasing them in Ojos Indígenas Reserve in Punta Cana in an effort to create additional populations of the hawk in other protected areas on the island. Assisted Dispersal has resulted in the formation of 15 breeding pairs to date and 22 wild fledged young!

Another aspect of the project I could mention is our collaboration with Fundación Grupo PUNTACANA and the Disney Conservation Fund to retrofit dangerous power lines preventing electrocutions of not only Ridgway’s Hawks, but other species of birds as well. A whole other blog post could focus on our program to provide free chicken coops to individuals in small communities, an effort to help avoid conflicts between humans and hawks that sometimes prey on young poultry.

Instead, today I would like to tell you about our community development and our environmental education programs. One important aspect of The Peregrine Fund’s work, is to improve the lives of people in areas where we are conserving birds of prey, whether through training, educational activities, or employment opportunities.

In the communities surrounding LHNP we are working with 17 local technicians that we have trained and hired. Some are in their 40s and 50s and have been with the project since its inception. Others are in their early twenties and are just beginning their careers. In small towns around LHNP, there are limited job opportunities and our project is able to provide economic benefits, employment and valuable training in skills such as tree climbing, data collection, bird banding, nest searching, as well as computer data entry and leadership skills.

We began our environmental education program in Punta Cana in 2013, after three of our released Ridgway’s Hawks were shot in a nearby community. Since then, we have expanded our efforts and now work with over 15 communities and have reached over 7,000 individuals in a wide radius around the release site through door-to-door visits, educational presentations, school activities and teacher training workshops. One of the most fun and successful activities that we do every year (as part of our Caribbean Endemic Bird Festival) is the celebration of Ridgway’s Hawk Day, May 25^th.

Thanks to a generous donation from BirdsCaribbean, this year we celebrated Ridgway’s Hawk Day with three separate activities around the country! The first, we held with two of our local partners: the National Zoo (ZOODOM) and Fundación Propagas. Schoolchildren from Santo Domingo were treated to a close-up view of a live Ridgway’s Hawk at the zoo, and also participated in an art project, receiving a raptor inspired mask at the end of their visit.

The second and third Ridgway’s Hawk Day activities took place in Punta Cana, where, with the help of Fundación Grupo PUNTACANA – another important local partner, we hosted two celebrations on June 1^st and 2^nd. Over 80 children visited our Ridgway’s Hawk release site in Punta Cana and saw young hawks up close, learning about the release process and the importance of protecting wildlife. Participants also learned how to use binoculars on a nature walk while practicing birding in forests and lagoons. The children also created beautiful art, painting and coloring on recycled wood – which focused on Ridgway’s Hawks, nature, and other wildlife observed during their visit. Select pieces will be displayed at an event in a local art museum early next year.

To end the day, we headed down to a nearby beach where the kids played games in the sand, learning about the importance of a balanced ecosystem for creatures both on land and in the sea. After a picnic lunch under the shade of nearby trees, students clapped hands and swayed to the rhythm of drums during an interactive dance performance by one of our volunteers, in a full Ridgway’s Hawk costume!

We have already begun to see the positive effects of our education efforts in communities, especially in the attitudes of individual people. Most notably, in the community where our three Ridgway’s Hawks were killed a number of years ago, we now have a nesting pair of hawks who just fledged two perfectly healthy young! The entire community knows of the presence of the hawks and is now actively supporting their protection!

Though we still have a long way to go to ensure the conservation of the species, we continue to be encouraged by the changes we see taking place, making great strides each year and we look forward to the day that the Ridgway’s Hawk is no longer an endangered species.

The Vampire Diaries: Searching for Seabird Blood in the Sunny Caribbean

In the pursuit of wildlife research, I’ve climbed cliffs, dodged black bears, ridden in tiny planes through turbulent mountain air, jumped into surging ocean waters, and hiked alone through remote wilderness. None of these activities have scared me as much as handling my first Roseate Tern chick, a delicate ball of fluff just hours from the egg.

As I prepared to take a blood sample, hands shaking, I carefully stretched out the chick’s back leg, searching for the threadlike femoral vein. Anxious tern parents called and swooped above us in the early morning sky, and the chick peeped quietly in my hand. I angled the needle and, taking a deep breath, slid it gently in. My reward was a perfect bead of red blood. I transferred the blood into a vial of storage solution, handed Daniel the chick to return to the nest, and leaned back to savor the short moment of victory. One sample down, 29 to go.

This spring I started my first full field season researching Caribbean Roseate Terns. These gorgeous Larids (bird family Laridae includes gulls, terns, and skimmers) are an especially challenging seabird to study, as anyone who’s tried will be quick to tell you. Like many seabirds, Roseate Terns nest on small islands, which offer a relatively predator-free habitat to raise chicks. Unlike many seabirds, they move colony sites almost yearly, for reasons we haven’t yet been able to determine.

In the Virgin Islands, which host ~50% of the Caribbean population, Roseate Terns have over 26 potential nesting cays that they choose from. That means that any research activities must first involve locating the birds, then figuring out a plan for that unique colony site. Caribbean Roseate Terns are also easily disturbed, and are prone to colony abandonment. Too much research activity in the colony could lower their reproductive success, which is the opposite goal of our efforts. For all these reasons, determining colony success through means such regular nest checks is not possible for this population, forcing us to get a little more creative.

Because Roseate Terns have such a large range, and aren’t too interested in country boundaries, effective conservation planning for this species requires collaborating across borders. I’ve teamed up with researchers from several organizations in the Caribbean for this project, chief among them Susan Zaluski from the British Virgin Islands’ Jost Van Dyke Preservation Society and Daniel Nellis from the US Virgin Islands Division of Fisheries and Wildlife.

In addition to developing a standardized monitoring plan to use between the two territories, we are working to answer some of the basic questions regarding Roseate Tern ecology in the region. Because nesting cays are so difficult to regularly access, we’re using motion-activated game cameras installed at nests to be our eyes in the colonies. This year, we have cameras in six active colonies. We’re hoping that the images from these cameras will help us better understand the role of predation in colonies, as well as incubation behavior and hatching success.

Roseate Terns are declining across the Caribbean, and we don’t know why. Are population declines due to low nest success at colony sites, or to low adult survival on wintering grounds? The breeding season is only part of a Roseate Tern’s year, and come August they will leave the Virgin Islands. Band returns have indicated that the birds travel to wintering grounds in South America, but we know very little about their non-breeding movements.

Roseate Terns are smaller and lighter than other terns, and this has made following their movements using technology like satellite tags difficult. To answer some of the larger questions regarding population health and movement, we’re turning to another source: DNA. Caribbean Roseate Terns aren’t alone in North America—there is also a well-studied population in New England. These two populations are believed to share wintering grounds, but aren’t thought to interbreed. Such isolation is unusual for such far-flying seabirds, particularly as it’s thought that the migratory pathway of the Northeastern population takes them through the Caribbean.

We’re partnering with agencies in the US to determine relatedness between Caribbean and Northeastern Roseate Terns through genetic analysis. Genetic information will give us a better idea of the population health of Caribbean Roseate Terns, and will provide some intriguing clues on who they’re mixing with on their wintering grounds, which might better help us understand where they’re going.

Which brings us back to that first morning of sampling. It’s best to get blood from chicks less than 3 days old. Younger chicks are easier to catch, and their skin is thinner and easier to pierce with a needle. They also seem to heal more quickly, with bleeding stopping within seconds—sometimes too quickly for me to get a full sample. All these sampling considerations make geneticist researchers like myself sound particularly, well, bloodthirsty, and have led to us being characterized as “vampires.” It’s a nickname I’ll proudly answer to, knowing as I do all the amazing secrets hidden in that remarkable substance.

Unlike mammal blood, avian blood is nucleated, meaning that every blood cell contains copies of DNA. That DNA can tell us the history of an entire species and beyond, if only we can find exactly the right questions to ask and the right tools for answering them.

Figuring out the best timing for our DNA sampling required four separate boat excursions to locate the most accessible tern colony and estimate when the majority of eggs would hatch. After deciding that LeDuck island would be the best candidate for sampling, we returned early one morning to swim our gear onto the islands in waterproof coolers, then hiked through waist-length thorny brush to reach the terns. I set up my sampling station on a flat boulder, and Daniel and my visiting husband worked the colony, locating the tiny chicks and bringing them to me bundled up in hats, hands, pockets, and bandanas. We moved between colony sections to allow anxious tern parents to return to their nests, working as quickly as possible to minimize stress to the colony.

In all the haste, I still made sure to take a moment to breathe, look around, and enjoy the view. All that research planning, all those questions, came down to two short hours in the field and those 30 precious vials of blood. A year of collaborative effort went into my sitting on that boulder, first chick in hand, and I wanted to make sure that I took the time to appreciate it.

After the Birds Caribbean conference in Cuba (hope to see you there!) I’ll be heading back to Louisiana to lock myself in the lab and get started on analyzing all this data. I’m so excited to see where these results take us, and look forward to sharing my findings with you all in the future!

Paige Byerly is a PhD student at the University of Louisiana at Lafayette. Her research investigating genetic diversity among Roseate Terns in the Virgin Islands is supported by a grant from the BirdsCaribbean David S. Lee Fund and a research fellowship from the National Science Foundation. The Caribbean Roseate Tern, is a threatened metapopulation of Sterna dougallii dougallii, and thought to be declining across its range. Her research will help conservationists better understand the migratory ecology and population vulnerability of Roseate Terns.

Birds are inspiring creatures. Their amazing migrations and behaviors capture our imagination, and their global presence lets us appreciate them wherever we are in the world. The power that birds have to bring people together across cultures, languages, and international borders is truly exceptional. Global Big Day is the realization of the magic of birds—a single day where the birding world unites in a shared pursuit, seeking to answer the simple question: how many birds can be seen in one day?

On 13 May 2017, almost 20,000 birders from 150 countries around the world joined together as a global team, contributing more than 50,000 checklists containing 6,564 species—more than 60% of the world’s birds. This is a new record for the number of bird species reported in a single day!

With one of the highest endemic species ratios, the avifauna of the West Indies is important to have represented on Global Big Day. In the eBird Caribbean region*, 280 species were seen – Check out the list of species reported. Ninety-two participants submitted 334 checklists. These totals are lower than last year’s Global Big Day, but perhaps some people still have not entered their data. Note that it is not too late – your checklists will still be counted!

Birders in Trinidad and Tobago sighted the most number of species—164 in the region. The Bahamas and Puerto Rico were in second and third place with 129 and 95 species observed, respectively, and there was participation through many of the islands—21 countries/islands submitted checklists (see how your country compared to the rest of the region and world here). Thanks to all of you that helped spread the word and participated!

Global Big Day is a celebration of birds. By bringing people together, Global Big Day showcases the great birds from each region—helping bring awareness to birding and conservation regionally and globally. Cornell Lab of Ornithology reports that this year (as in previous Global Big Days), the friendly competition in South America continued to evolve as an inspiring story, with four countries topping 1,000 for the single-day tally: Brazil, Ecuador, Peru, and Colombia. In past years Brazil and Peru had always vied for the #1 slot for species totals, and in 2017 there is a new champion: Colombia. Next year, let’s set a goal for the West Indies to see the most endemics in a region, it can be done!

Thanks again to everyone who participated and made this Global Big Day successful. We hope you had a great time and will continue to participate in eBird Caribbean and future Global Big Days. Of course, eBird Caribbean doesn’t only exist on one day of the year. Global Big Day is just one of 365 opportunities/year to be a part of a global network of birdwatchers, researchers, and conservationists working together with a shared passion for birds. Any bird that you see, anywhere, at any time, can become a part of this global resource—helping your fellow birdwatchers as well as the birds that we all care about. So take a look at eBird Mobile, or how to find birds near you. Go out, explore, have fun, and let all of us know what you saw. Your sightings can help change the world. We’ll see you out there.

*The countries comprising the eBird Caribbean portal consist of the West Indies plus Trinidad and Tobago, Aruba, Bonaire, Curaçao, and Bermuda.

Finding Bahama Oriole Nests in the Pine Forest—Reflections from a Young Scientist (Part 2)

Dan Stonko joined Dr. Kevin Omland’s research group studying the Bahama Oriole as an undergraduate at the University of Maryland, Baltimore County. With the research team, he traveled to Andros in the Bahamas to search for the nesting Bahama Oriole and gained invaluable field experience while making memories of a lifetime (check out his recent blog article). Here, Dan summarizes his perspective of science, education and mentoring as learned through his undergraduate experiences.

As an undergraduate, I have been incredibly lucky with the opportunities I’ve received. Taking on undergraduate students into your lab can be risky in itself for multiple reasons – we are usually inexperienced, require time and effort to train, and usually can’t contribute nearly as much as a higher-level student/employee. For these very reasons, I have come to be evermore grateful for getting the kinds of opportunities as amazing and impactful as I’ve shared in my previous blog post. Whenever anyone asks me about our lab’s work, I start off by discussing the science and research. Before long, I tend to catch myself getting into the unexpected and memorable lessons I’ve learned. So here are just a few of those lessons:

1. The most impactful learning can happen outside of the classroom

Okay, this might sound cliché. But when I started college, I felt certain that most of my time in college would be spent either in class or studying. I then reasoned that most of my learning would therefore happen in class or while studying.

I graduate in two months and can definitely confirm that this is how I spend most of my time. Yes, as a biochemistry major I have gained much of the central scientific knowledge through classes. However, the science I study has come to life through my research. I’ve applied my knowledge to real-world situations, designed experimental procedures, built relationships with mentors, collaborated with peers, and worked in the field. These lessons and experiences will be with me forever, and they’re the kinds of things you can’t get by simply sitting in class or reading a textbook.

2. Science is a verb

Whether doing field research in a pine forest, looking through a microscope or telescope, or mixing chemicals in a beaker – I have come to see science, in its purest form, as the pursuit of knowledge. Not a noun, but a verb. It is the act of careful observation, meticulous investigation, and ceaseless questioning of the things around us. If the pieces fit together just right, our curiosity can be rewarded with an expanded understanding of our world.

3. Modern discoveries in science are made possible by our predecessors

Isaac Newton once wrote that, “If I have seen further it is by standing on the shoulders of giants.” Before I got involved with research, that adage sometimes crossed my mind; often it would do so while reading or hearing about some unimaginably complex discovery that undoubtedly depended on contributions from many people. This thought always gave me a fundamental admiration for the explorers and scientists who came before us. As a researcher, I’ve gained a new and deeper understanding of Newton’s words.

Going into our first trip, most of what was known about the Bahama Oriole came from earlier research by Dr. Melissa Price. Her work provided the most recent population estimates and gave thorough information on the reproductive ecology of the species. Whether I was in the field collecting data or in lab drafting the manuscript to share our findings – I knew that her work (and that of countless others) influenced our work. It’s a humbling reminder for a scientist to keep in mind: with every day that we work and every discovery that we make, our progress is possible because we stand on the shoulders of the giants who mentor us and came before us to provide our foundation.

4. Observation is the true driver of science

Some areas of popularized science today seem to reinforce (what I believe to be) a subtle yet significant misconception, which presumes that questions are at the bedrock of any scientific endeavor. However, I have found observations are the truest foundation. Countless scientific advances throughout history didn’t arise by seeking answers to specific questions. Even when questions have led to advances, initial observations were always there to lead to those questions in the first place. In other words, we first make observations about our world, which then allow us ask questions such as: What? Why? When? How? It all may seem like semantics, but I believe that grasping this subtle distinction instills a sense of deserved respect for observation as the most critical scientific tool for discovery.

Some of our research on this first trip was oriented towards specific questions or goals, such as the distance sampling surveys that we used to estimate population size. The majority of our efforts, however, occurred without particular goals and depended simply on observation (e.g. catching and banding orioles, recording observations on bird behavior, and finding nests). At first, this idea of working without a particular goal in mind may seem counterintuitive. Nevertheless, the work proved invaluable as it led to us finding orioles nesting in the pine forests. This trip serves as reminder that simply listening, watching, and being present to make observations can lead to unexpected discovery.

How many birds can a world of birders find in one day? Hopefully, you will join us to find out on May 13th — Global Big Day. This is the single biggest day for eBird and we’re inviting everyone to spend some time counting and enjoying Caribbean birds to help support global conservation efforts (and to have some fun in the process). Last year was a huge success that broke records around the world and across the Caribbean. The question is: Can we do it again?

More than one hundred Caribbean birders participated in last year’s Global Big Day, setting a new Global Big Day record for the Caribbean itself- 428 species! Thank you for making this possible. Your contributions to the past two Global Big Days have set back-to-back world records for the most bird species seen in a single day. Last year’s Global Big Day featured more than 60% of the world’s bird species in a single day (6,299!), with sightings coming in from more than 17,500 eBirders spread across 154 countries.

Want to be a part of the fun this year? If you need an excuse to go enjoy birds on a lovely weekend day in May, we’ve got you covered. The West Indies, with it’s 175 endemic bird species, along with it’s near endemics and endemic subspecies, will be key in gathering a snapshot of bird distribution around the globe.

If you’re looking to get started preparing for this year’s Global Big Day, here are four quick ways to have the most fun:

“Scout” your birding spots for May 13. Finding where the birds are ahead of time makes the big day birding more fun, and also gives you more chances to be out enjoying birds. Perfect. Learn how to use eBird to find birds.
Hopefully, a few migrants, like this Ovenbird, are still lingering in the islands and will be included in some checklists! (photo by Bill Hebner)

Use eBird Mobile. This free data-entry app makes it so you don’t have to enter your sightings at the end of the day, and tools like Quick Entry mean you have less time with your face in a notebook. Get eBird Mobile here.
Get a friend involved. Perhaps this is a good birding buddy, or someone who has never been birding before. Make it a friendly competition, or join forces as a Global Big Day team, and put your marker on the global participation map. Share on social media using #eBird_GBD. Check out the Facebook event.
Participating in Global Big Day is a great way to celebrate the Caribbean Endemic Bird Festival, ongoing now! Make this a part of your celebration and organize a birding outing with family, friends or your community.

No matter what you do—have a great time, enjoy the birds around you, and let us know what you find! We’re excited to see what we can achieve together on Global Big Day.

Finding Bahama Oriole Nests in the Pine Forest—A Victory over Rocks and Poisonwood (Part 1)

March 28, 2017

First Photographic Record of Kirtland’s Warbler in Cuba!

Kirtland’s Warbler spotted on Cayo Guillermo Cay off the northern coast of Cuba. The bird (male) is identified by its yellow underparts with black streaks on flanks, white undertail coverts, blue-gray upperparts with black streaks, and conspicuous white eye-crescents that contrast with black lores and forehead. This appears to be a first winter male as the bird shows some brown on its upperparts and face. (photo by Anne Goulden)

Anne Goulden, from Sarnia, Ontario, spotted and photographed a Kirtland’s Warbler (Setophaga kirtlandii) on a recent birding trip to Cuba, making this the first “official” sighting of the bird on Cuba.

Anne Goulden has been an avid birder for ten years. “Birding has been a hobby—make that an obsession—since 2007,” she says. Anne had just finished a 9-day birding tour in Cuba with Eagle Eye Tours and had arranged to stay on an extra three nights at their last stop, the Cayo Coco Cays located along the northern coast of Cuba. She wanted to bird at a leisurely pace on her own before returning home. The group was staying at the Iberostar Playa Pilar Hotel in Cayo Guillermo, one of the Cayo Coco Cays, known as a birding hot spot because of the Cuban and regional Caribbean endemics that live in the area.

On February 22^nd Anne’s tour group birded for about 1 km along the road between their hotel and the Playa Pilar Beach looking for a Bahama Mockingbird, a species found only in a few locales in Cuba, Jamaica, and in the Bahamas and Turks and Caicos Islands. “We were out for about an hour and were lucky enough to find a few Bahama Mockingbirds in addition to warblers and a few local birds,” Ann commented. The bus returned to the hotel to send everyone off to the airport to return home.

This photo shows the yellow throat, breast and belly, white undertail coverts and black lores of the Kirtland's Warbler. The broken white eye ring is also clearly visible. Female Kirtland’s are similar to males but have no black on the face and their upperparts and face are more brown.

The next morning, February 23^rd, Ann set out at on her own at about 7am along the same road to see what else she could find. She spotted an unfamiliar bird in a tree with red berries about an hour into her walk. “I wish I could say I knew what it was, but I didn’t,” said Anne. “I knew it was a warbler, but that was about it. I managed to get a few poor photos before it flew off.”

After Anne returned home she looked through her pictures, but still couldn’t place the bird. Ann was disappointed that her photos were not in sharp focus, but she knew that they were clear enough for an ID. She sent the pictures to two local birders who both suggested Kirtland’s Warbler, but it wasn’t even in Anne’s book so she did not include it in her e-bird checklist until the bird was also positively identified as a Kirtland’s by her two tour leaders, Hector Gomez de Silva and Colin Jones (the ID was also confirmed by eBird Caribbean reviewers). The individual appears to be a juvenile male (first winter).

“I was very excited to have this bird confirmed as a Kirtland’s Warbler,” exclaimed Anne. “I live in Ontario so know about the Kirtland’s and what a rare bird it is, but I never expected to see one in Cuba. I have only had a fleeting look at this bird once before, in Ontario in 2014.”

One of the rarest songbirds in North America, the Kirtland’s Warbler is listed as “Endangered” under the Endangered Species Act of 1973. Its current status is Near Threatened on the IUCN “Red list of Threatened Species,” upgraded from Vulnerable in 2005, thanks to successful recovery efforts.

The Kirtland’s Warbler winters primarily in the Bahamas Archipelago, which includes The Commonwealth of The Bahamas and the Turks and Caicos Islands. It inhabits early successional broadleaf scrub or shrubby habitats, where it feeds on fruits, insects and spiders. Recent surveys indicate that the warblers most commonly winter in the central islands of The Bahamas including Eleuthera, Cat Island, San Salvador, and Long Island.

The Kirtland’s Warbler was spotted feeding on berries of the Gumbo Limbo tree (Bursera simaruba), a very important food source for many birds, including migratory warblers fattening up in their Caribbean wintering grounds for their long journey north to their breeding grounds in spring. (photo by Anne Goulden)

Kirtland’s Warblers are known to overwinter outside of the archipelago, however, as documented by a photograph of an individual during a Christmas bird count on Bermuda in 2004, and a bird photographed in Key West, Florida this past winter. In addition, there have been sight records of wintering Kirtland’s Warblers from northern Mexico, Dominican Republic, and Cuba. Unfortunately sight records alone are insufficient for “official” documentation, which requires either a good photo or a specimen of the bird. Thus, the fact that Ms. Goulden photographed a Kirtland’s Warbler (with typical field marks visible) verifies for the first time the “official” presence of the warbler in Cuba.

The habitat where the bird was found and the photo of the warbler feeding on the fruit of Gumbo Limbo or Gum Elemi (Bursera simaruba) are all typical of the habitat and behavior of the wintering Kirtland’s Warblers observed in The Bahamas. In addition, the first Cuban sight record of the warbler in 2006 was also from the Cayo Coco cays. The cays located off Cuba’s north coast have typical scrub vegetation including Black Torch (Erithalis fruticosa), Wild Sage (Lantana involucrata), and Snowberry (Chiococca spp.) which also produce the fruits favored by the warbler. The cays also host specialties such as the Bahama Mockingbird and Thick-billed Vireo, both of which are typical birds of the Bahamian bush.

In recent years, more and more observations of the Kirtland’s Warblers have been made during the winter months. Some of the increase in observations might be attributable to more birders in the field in the warbler’s habitat. The more likely explanation, however, is that increased wintering grounds observations are attributable to the increase in the size of the Kirtland’s Warbler population at least since the 1970s and 1980s. This increase in the population of the warblers is directly attributable to the success of the intensive recovery effort focused on the warbler’s breeding grounds in Michigan.

Kirtland’s Warbler breeds in early successional Jack Pine (Pinus banksiana) habitat primarily in Michigan with recent breeding now established in similar habitat in southern Ontario and Wisconsin. Habitat loss and degradation coupled with nest parasitism by Brown-headed Cowbirds were the primary factors contributing to the species decline to record low populations of the 1970s and 80s. In that period, counts of approximately 200 singing males on the breeding grounds were typical, whereas today, thanks to habitat management and cowbird control, the recent breeding ground censuses of singing males is approximately 2,350 singing males. [The biologists are not being sexist, its just that females are difficult to detect and count in contrast to the males which are obvious as they sing on their territories in early spring; the sex ratio is assumed to be 50:50]. Thus the abundance of recent winter observations of the Kirtland’s Warbler is a testament of the success of the conservation program directed at the recovery of this endangered species.

A recently published article by Dr. Nathan Cooper and his colleagues from the Smithsonian Institution suggests the possibility of some Kirtland’s Warblers occurring in Cuba. The research, based on use of light-sensitive geolocators to track the warbler suggests the occurrence of Kirtland’s Warblers wintering in Cuba; the photo obtained by Ms. Goulden establishes the fact. Congratulations to Ms. Goulden!

“I don’t live far from Michigan and hope in the next year or two to make a trip to the Kirtland’s Warbler’s famed breeding grounds,” said Anne. “Seeing this rare bird on its wintering grounds is, however, probably the most exciting thing that is likely to ever happen to me as a birder! I’m thrilled I was in the right place at the right time and managed to get a photo of the bird. It’s certainly rewarding for ordinary citizens like myself to contribute to science through our birding activities and use of eBird Caribbean!”

BirdsCaribbean Awards David S. Lee Fund Grants to Six Worthy and Exciting Projects

David S. Lee Fund award recipient, Grenadian Wayne Smart, scans for seabirds in the Grenadine islands with his spotting scope.

BirdsCaribbean is excited to announce the first award recipients of the David S. Lee Fund for the Conservation of Caribbean Birds. We are extremely pleased to support these dedicated young scholars as they pursue important research that will increase our knowledge of and inform conservation management decisions for Caribbean birds. The award recipients are: Wayne Smart, Maya Wilson, Spencer Schubert, Ramon Williams, Holly Garrod, and Paige Byerly.

The David S. Lee Fund was established in 2016 to recognize the scientific and conservation efforts of David S. Lee, a biologist and naturalist dedicated to Caribbean biodiversity. The award funds innovative avian conservation research in the Caribbean. All projects demonstrate a commitment to engaging with local scientists, government officials, organizations and communities, as appropriate, to involve them in the research, share results, and build interest in local birds and their conservation.

Thanks to support from the David S. Lee Fund and contributions from an anonymous donor, BirdsCaribbean is able to provide grants of $900 to $1,000 for six exceptional conservation research projects in 2017, the first year of funding for the award. Congratulations to all the dedicated and hard-working student recipients, who embody the vision that we all share of a bright future for the conservation of Caribbean birds. We look forward to hearing about their work in forthcoming articles and publications.

Seabird nesting performance, colony declines and invasive predators in the Southern Grenadines.

Seabird colonies are declining globally for multiple reasons such as habitat loss, introduced predators, and poaching. The Grenadines support five Important Bird Areas and host a number of seabird colonies, though little is known about local seabird decline. Wayne Smart will conduct field work on five uninhabited islands off the north coast of Grenada this summer. By interviewing locals, monitoring nests, and deploying cameras and two types of traps, he anticipates gathering valuable baseline knowledge about the current size and reproductive success of seabird colonies in the Grenadines and how they are impacted by introduced rats. The data will inform seabird management decisions for a community-based conservation program.

Population biology, life history and ecology of the Bahama Swallow (Tachycineta cyaneoviridis): informing conservation of an endangered species.

Maya Wilson, Virginia Polytechnic Institute and State University

The Bahama Swallow is an endangered species endemic to Grand Bahama Island, Great Abaco Island and Andros Island in the northern Bahamas. The swallow relies on pre-existing cavities in Caribbean Pine (Pinus caribaea), which are only found in large tracts on these island (they are also found on New Providence Island though the breeding Bahama Swallow likely was extirpated from here). Maya Wilson will undertake her third and final field season to investigate the population abundance, life history traits and nesting resource limitations of the Bahama Swallow. She is collaborating with the Bahama Oriole Project to develop survey techniques to estimate population and habitat data for both species. In addition, gene flow between islands will be analyzed from samples collected during mist netting efforts. Maya’s research will provide important information about two endangered Bahama endemics that will be used to inform conservation strategies for these species and their habitats.

In Hispaniola, less than 15% of the original wet forest cover remains, primarily due to deforestation for cattle ranching. It is well known that frugivorous birds provide vital ecosystem services that aid in forest growth, such as pollination and seed dispersal. Spencer Schubert will travel to the Dominican Republic this summer to investigate the role of artificial perches as a strategy to increase natural seed dispersal and reforestation. From his previous work in the area, he has identified 24 species of frugivorous birds that aid in seed dispersal. Working with the local NGO Plan Yaque, he intends to install artificial perches in different spatial patterns and measure frugivore use and seed deposition. Results from this study will directly benefit Plan Yaque and their ongoing reforestation effort, local farmers, and the biodiversity and avian communities that rely on forests.

Distribution, diversity, and abundance of Grenadian birds, including endemic and restricted-range species.

Ramon Williams, University of Manitoba

Like many islands in the Caribbean, Grenada is undergoing rapid development leading to increased human disturbance and habitat loss. The conservation status of Grenadian passerines in response to development is poorly understood as there is little information regarding the distribution, diversity and abundance of species across the island. Thirty-five passerines are found on Grenada, including the critically endangered Grenada Dove (Leptotila wellsi), the endangered Grenada Hook-billed Kite (Chondrohierax uncinatus mirus) and the endemic Grenada Flycatcher (Myiarchus nugatory). Ramon Williams will begin field work this summer to estimate passerine species diversity and abundance, in addition to quantifying vegetation structure, in representative habitat types across Grenada. This study will produce a comprehensive assessment of the status of passerines on the island, potentially identifying areas of conservation priority.

Nest response of Broad-billed Todies (Todus subulatus) to an invasive nest predator, the small Asian mongoose.

Holly Garrod, Villanova University

The Broad-billed Tody is endemic to the island of Hispaniola. Like all todies, this species nests on the ground by building burrows in embankments. This nesting strategy makes todies extremely vulnerable to introduced predators, such as the small Asian mongoose (Herpestes javanicus auropunctatus). This summer, Holly Garrod will return to the Cordillera Central region of the Dominican Republic – where she conducted pilot research in 2016 – to monitor nesting todies and nest predation. She is interested in the behavioral differences of todies in undisturbed and disturbed sites and how this might affect reactions to nest predators and reproductive success. Understanding how birds respond to predators under different environmental conditions has the potential to improve anti-predator management techniques for native bird conservation.

Conservation genetics of the Caribbean Roseate Tern

The Caribbean Roseate Tern, a threatened metapopulation of Sterna dougallii dougallii, is thought to be declining across its range, though the trajectory of the population is not well understood. Paige Byerly will undertake a project to analyze the genetics of the Caribbean Roseate Tern in order to investigate gene flow patterns between this population and the similar Northeastern Atlantic population. It is thought there is no movement between the two groups; such genetic isolation has the potential to negatively impact population viability. In addition to gene flow, this analysis will yield information about genetic diversity and effective population size. Samples will be collected this summer from populations in the U.S. Virgin Islands and Massachusetts. Results from this study will provide researchers and conservation managers with valuable new information about connectivity, migratory ecology and population vulnerability.

Hurricanes and Birds Part 2: How Do Caribbean Birds Survive?

Can Caribbean bird populations survive hurricanes? Or perhaps we should ask, how do they manage to live through the storms’ fierce onslaught as well as survive the aftermath when there is little food and shelter?

In Part 1 we looked at the terrible damage caused by Hurricane Matthew to the human life, infrastructure, wildlife and ecosystems on some of our islands. Matthew arrived just a couple of months ago. Some communities are only just picking up the pieces, and for many, life remains a struggle.

Just as with humans, some birds can “get back on their feet” faster than others. If forests are lost, as in Haiti during Hurricane Matthew, birds are essentially homeless, like a man whose house has blown down, and their chances of survival are not good. As humans are rebuilding their lives, birds have to struggle on with theirs, too, in an environment that has become bleak and hostile, almost overnight. It will take time to restore some kind of normality. Fortunately, like humans, birds are remarkably resilient and they can (and do) bounce back.

Shorebirds like Piping Plovers that spend the winter in the Caribbean are vulnerable to being killed by hurricanes as their habitat takes a direct hit from the storm and they have no place to hide. In addition, their sand dune roosting habitat can be damaged. (photo by Walker Golder)

Recent studies of hurricane effects on birds indicate that these storms have both direct and indirect effects on birds. Direct effects are most likely to cause mortality in those birds that have no place to hide, especially aquatic bird such as waterfowl, pelicans, gulls and terns, sandpipers, plovers, herons and egrets. In a severe storm, their habitats will likely be swamped by storm surges, and the strong winds (often most powerful along the coast) will destroy them. Heavy rains, resulting in floods and landslides, will swamp them. Many land birds can avoid the direct effects of hurricanes by hunkering down on the ground or sheltering in low vegetation, but land birds are also killed by hurricanes.

Hurricanes often destroy favorite feeding trees such as Sea Grape (shown here) and Pigeon Plum, beloved by fruit eating birds, leaving many birds hungry and wandering in search of alternative food sources after a hurricane. (photo by Lisa Sorenson)

Indirect effects, however, may not only cause mortality but have the longest lasting impact on bird populations. These include loss of food resources or foraging substrates, increased risk of predation, loss of nests and nest or roost sites, and microclimate changes.

In the short-term, birds respond to these indirect effects by changing their diet, habitat, and foraging locations. It should be no surprise that after hurricanes birds will quickly abandon heavily damaged and exposed sites and move into less damaged sites where there is a better food supply and cover from predators. Often birds will wander widely in search of food in the aftermath of storms and feed on foods that are not normally in their diet (as described in Part 1 of this article).

In the first breeding season after a hurricane, breeding is usually disrupted as some species may not be able to find good nesting places, or food may not be sufficient for females to build up the reserves needed to lay eggs and undergo incubation. There might also be shortages of food to feed young. And of course, a number of breeding birds may have fallen victim to the storm. These factors usually result in a decline in breeding success and consequently fewer baby birds post-hurricane for many species, which can shift population age structure.

White-cheeked Pintails are a tropical duck that may breed when conditions are good, which can happen after a hurricane when ponds become flooded and abundant aquatic macro invertebrates provide food for breeding females and their ducklings. (photo by Jackie Cestero) — White-cheeked Pintails are opportunistic breeders and sometimes nest in the fall following a hurricane when ponds become flooded and abundant aquatic macro invertebrates provide food for breeding females and their ducklings. (photo by Jackie Cestero)

In tropical climates where some birds breed opportunistically or all year-round, such as grassquits, they can begin to breed again as soon as conditions improve. As vegetation recovers, terrestrial birds may respond to outbreaks of herbivorous insects (e.g., caterpillars) as defoliated plants leaf out, and to increases in flowering and fruiting. These food resource blooms several months or years after a hurricane can eventually increase breeding success as pairs may produce multiple clutches in a season due to abundant food. Similarly, tropical waterbirds such as White-cheeked Pintails may nest opportunistically in the fall in the weeks following a hurricane when heavy rainfall floods wetlands leading to flushes of aquatic macro-invertebrates, the high protein food that females need to lay a clutch of eggs.

Which bird species are most at risk during and after a hurricane? These tend to be those with a diet of fruit, nectar or seeds (hummingbirds, bananaquits, pigeons, doves and parrots, among others). Birds that live or forage in large, old trees – such as woodpeckers, owls and more – may also suffer; sadly, these noble trees often bear the brunt of the storm. Birds that live in closed forest canopy, that depend on a particular “niche” ecosystem with its own peculiar mini-climate, and/or that live in habitats in which the vegetation recovers slowly are all vulnerable.

The Grenada Dove population suffered a substantial decline and is still recovering from Hurricane Ivan, a Category 5 which hit Grenada in 2004. (photo by Greg Home).

These vulnerability traits may increase the risk of severe population decline in those species with small populations isolated in small habitat fragments which includes many of the islands’ endangered endemics of course. For example, the Grenada Dove suffered a substantial decline in its already small population as a result of Hurricane Ivan in 2004 (estimated at 180 doves before Hurricane Ivan), although obtaining a precise population estimate was challenging as the doves moved out of their traditional sites and stopped calling. The most recent census (2013) suggests that the dove is still recovering from this loss many years later.

How can we humans help birds after the passage of a hurricane? One important way is by providing food. Hang up bird feeders – including hummingbird feeders, as nectar from flowering plants and trees is likely to be in short supply, and bird seed. This can help birds survive until their natural foods recover. We should not forget water either! There is usually either too much or too little water available after a hurricane. Birds need plenty of clean water to recondition their battered feathers and of course, to drink. Birds do get dehydrated quite quickly, especially in the hot weather. We should also try to replant as soon as possible – both slow- and fast-growing native trees and plants – to provide shelter, food, and nesting sites.

Hurricanes such as Matthew are tests of endurance, resilience and adaptability. With climate change life will likely not get any easier, and we can expect the unexpected. While people can prepare for more intense storms that may come our way in the future, our birds cannot plan for the future. Let us see what we can do to protect our birds – whose lives are literally turned upside down by such storms – and their habitats. And, if the worst happens, let us try to help them recover; it’s the least we can do.

Hurricanes and Birds Part 1: Mean Hurricane Matthew

Well, the Atlantic hurricane season is finally over, and island dwellers in the Caribbean can breathe a sigh of relief. The 2016 season that ended on November 30 was an “above normal” one, with 15 named storms, including 7 hurricanes – the deadliest season since 2005. It was unusual in many ways; a certain storm named Matthew certainly behaved strangely – and extremely badly. Matthew was a long-stay visitor to the Caribbean, moving very slowly, and far to the south; then turning north, as if he was doing a tour of the islands. At that point, Matthew decided to wreak havoc in Haiti, eastern Cuba and the Bahamas before descending on the southeastern seaboard of the United States. Matthew was a high-intensity storm, and he was mean.

An estimated 1,700 people lost their lives as a result of Matthew and damage amounted to some US$10–12 billion. But what of the ecological harm, and in particular the damage to birds and their habitats? The Caribbean is still counting the cost. Matthew made landfall on Haiti’s Tiburon Peninsula on October 4th as an intense Category Four storm – the strongest storm to directly impact Haiti since 1964. Haiti’s infrastructure is weak, and deforestation remains a major problem. Matthew brought very heavy rainfall along with him, and widespread flooding and landslides occurred, taking hundreds of lives. Worse still, the strong winds (well over 100 miles per hour) destroyed forest habitat as well as crops.

Erika Gates inspects damage at Sea Gate Lane.

The hurricane was a huge setback for reforestation efforts in Haiti, which had achieved 17 per cent tree cover – almost half of this forest in the Grand’ Anse Department (also the nation’s “breadbasket”). Sadly, this southern region was one of the worst affected by Matthew. As a result of the loss of trees there, bird populations suffered terribly. Dead birds (doves, woodpeckers etc) were found. It is feared that during Hurricane Matthew birds had no safe place to weather the storm, and large numbers perished. In the aftermath, the already degraded habitat was largely destroyed, offering little or no food or shelter for surviving birds.

Reports from the Bahamas were also quite grim, post-Matthew. Grand Bahama took a direct hit from the storm’s eyewall and suffered extensive damage. In some areas, almost all homes were damaged or destroyed and there was widespread flooding. Fortunately, there were no casualties – on the human side. However, bird guide Erika Gates reported the loss of all native mature trees (Poisonwood, Gumbo Limbo, Mahogany, and more) at her Garden of the Gates bird sanctuary and in the Westend and Freeport areas. Nevertheless, many small bushes remained, providing food for the birds after the storm.

Pericles Maillis reported from New Providence that he had hundreds of starving White-crowned Pigeons on his farm after the hurricane. “Black clouds” of them fed ravenously on cracked corn he put out, a food source that they normally do not come to like other doves.

There is always hope. Many migrants were observed two days after the storm, Erika reported. She surmised they must have survived by staying low on the ground, or in limestone cavities. Despite sustained high winds for more than eight hours, many wading birds such as ibises, egrets and herons – with their long, fragile legs – seem to have survived. One wonders how and where they sheltered! Hummingbirds such as the Bahama Woodstars and Cuban Emeralds were scarce for a while, however, due to the lack of nectar, and some birds appeared to have changed their feeding habits, at least temporarily; for example, the Greater Antillean Bullfinch was observed feeding on seed, instead of fruit. Other birds such as the Black-Throated Blue Warbler fed voraciously after the storm, almost ignoring the presence of humans close by. Some warblers were even seen feeding from trash cans!

Roaring winds, endless heavy rains and tempestuous seas – all those who have lived through hurricanes have vivid memories of this frightening and unnerving experience. The aftermath is often depressing and harrowing. How our fragile birds survive the storm and adapt to stressful conditions afterwards is nothing short of a miracle. In some ways, perhaps, they are more resilient than we humans!

Check out this link with side-by-side UAV (drone) photos that show the impact of Matthew on structures and tree cover. You can pan around in the photos and see that in the area covered there are no trees at all left standing. It is possible that the impact on birds and vegetative cover here may be longer term than other places with larger forest reserves – and lower daily demand for wood as fuel.

Opportunity to Study One of the Rarest Birds in the Caribbean – The Bahama Oriole Project

The Bahama Oriole (Icterus northropi) is the most endangered bird in the Bahamas. It is now restricted just to the Andros Island complex. There may be as few as several hundred individuals left, making it also one of the most endangered endemic birds in the entire Caribbean. Of greatest concern is that the oriole was driven from the Abaco Islands in the 1990s for unknown reasons. It is one thing to have a known killer lurking, but in the case of the oriole, what caused it to go extinct on Abaco is unknown. We hope to help preserve this charismatic and colorful species on Andros, which surprisingly is not that difficult to observe on certain parts of the island. Like many tropical birds, both the females and the males have elaborate coloration – both sexes are jet black with bright yellow patches over much of the body.

We began the Bahama Oriole Project last year with the overall goal of preventing the extinction of this beautiful oriole. The project is a collaboration between the University of Maryland, Baltimore County (UMBC) and the Bahamas National Trust (BNT). We have conducted several field trips to begin to determine how many orioles are left, and to learn what the major threats are to this species. We also need to learn much more about where the oriole spends its time throughout the year, including what it eats, how widely it ranges, and what its preferred habitats are for feeding and nesting. The last published estimates suggest as few as 300 individuals may remain. However, in May 2016 our field team, including students from the Bahamas and from UMBC, discovered previously unknown breeding populations deep in Andros’ vast pine forests. For several reasons, we are guardedly optimistic that good science and dedicated conservation measures can save this species from extinction.

eBird Caribbean sightings of the Bahama Oriole. The oriole is now confined to the Andros island complex, roughly 150 miles SE of Miami. Much of Andros is undisturbed wilderness, just a 15 minute flight from the huge resorts in Nassau. The oriole is now completely absent from the Abaco complex north of New Providence. (Recent sightings are shown in red, sightings older than 30 days shown in blue.)

Our first need is to recruit a PhD student to lead this research effort for the next five years. The student would be advised by Kevin Omland in the Biology Department at UMBC, in collaboration with researchers in the Geography Department at UMBC (Collin Studds and Matt Fagan) and researchers at the Smithsonian Conservation Biology Institute (Scott Sillett). The student could choose to focus on any one or two aspects of the project including: 1) population size estimation and habitat usage, 2) breeding ecology including cowbird parasitism and predation by introduced predators, 3) remote sensing and details of habitat usage in breeding and non-breeding season (in relation to fire and climate change), and 4) conservation genetics of populations on three different parts of Andros. Please contact Kevin Omland (omland@umbc.edu) and send a CV and short paragraph on research interests. The application target date for full consideration by the UMBC Biology Department is Jan 1, 2017.

We are grateful for the support and advice given to the project by BirdsCaribbean, and we plan to give updates on the project through blog posts and newsletter items. Meanwhile, we invite you to come to Andros to see all the great migratory and endemic birds there! Be sure to add to our knowledge by posting all sightings of Bahama Orioles to eBird Caribbean and to the “Bahama Oriole Project” on Facebook: https://www.facebook.com/BahamaOrioleProject/

Finally, the project needs ongoing assistance with everything from housing to transportation on Andros, so please consider either monetary or in-kind donations to the project through BirdsCaribbean. Thank you!

JCO Round-up December 2016

As the holiday season gets underway, we’d like to bring your attention to the most recent batch of articles published in the Journal of Caribbean Ornithology. All three studies stem from islands within the Greater Antilles, and all are valuable contributions to our growing knowledge of Caribbean birds. As all of the JCO’s publications are free and open-access, please don’t hesitate to pass them around, discuss them with colleagues, and reach out to the authors themselves if you are interested in learning more about their research.

1. We start off in the Espaillat Province of the Dominican Republic with an article entitled, Avian biodiversity in a pasture-dominated ecosystem, by Jason P. Hernandez. The work focused on gaining a better understanding of bird diversity in altered ecosystems; in this case, agricultural lands. Additionally, Jason collected data on the presence/absence of the Royal Palm (a tree species known to serve as important nesting habitat for several bird species in Hispaniola) as well as seedling recruitment success in pastureland that is heavily trafficked by cattle.

Thirty-three species – 32 of which are residents – were observed at the study site. Fourteen colonies of the endemic Hispaniolan Woodpecker were observed, all utilizing either dead or living Royal Palms, and 76% of the recorded bird species were thought to be tree dependent in some way. Royal Palm seedlings were considerably more abundant in riparian corridors compared to adjacent open pasture land, though both areas contained similar percentages of cattle paths. Though Royal Palms are known to regularly re-establish themselves in disturbed habitats, Jason hypothesizes that the hotter, drier conditions experienced in open pastures compared to cooler, more shaded riparian areas may explain the differences in recruitment. Jason suggests that beyond the good practice of leaving already-established trees throughout agricultural land, seedling recruitment must be considered to ensure future habitat. The replacement of conventional open pastures with sylvopastoral systems may become essential to supporting avian diversity in the presence of continued grazing practices.

2. Moving eastward from the island of Hispaniola, we find ourselves in Puerto Rico’s Maricao State Forest. Documentation of female song in a newly recognized species, the Puerto Rican Oriole (Icterus portoricensis) is written by authors Susanna K. Campbell, Alcides L. Morales-Perez, John F. Malloy, Oliver C. Muellerklein, Jin A. Kim, Karan J. Odom, and Kevin E. Omland. Campbell et al. set out to determine if female Puerto Rican Orioles sing, how that compares to their male counterparts, and finally how that information fits into the role of female song across the Caribbean oriole clade. The authors point out that female song is especially common in the tropics, whereas the majority of research on bird vocalizations has emanated from temperate regions, a geographic bias that only recently has gained more attention.

Results from the study were positive in confirming the first documented case – and in general – female song in the Puerto Rican Oriole, that males and females sing similar songs, and that when this is incorporated into the phylogenetic reconstruction of the Caribbean oriole clade, there is evidence that this clade likely had a common ancestor that had female song. Furthermore, the Puerto Rican Oriole is a tropic endemic displaying female song, providing further support that female song is correlated with tropical residence. Interestingly, female song was lost in one of the outgroup species of the clade, the Orchard Oriole, when the species moved to temperate residence and breeding. Campbell et al. theorize that female song may be more prevalent in the tropics because longer breeding seasons result in year-round territory holding, increasing the likelihood of female-female competition and the need for joint territory defense.

3. For the third article, we leap-frog back over Hispaniola to the island of Jamaica, where Aaron B. Spidal and Matthew D. Johnson bring us their work on Sexual habitat segregation in migrant warblers along a shade gradient of Jamaican coffee farms. Spidal and Johnson point out that in the face of ongoing declines in many species of Neotropical migratory birds, attention towards habitat modifications in tropical agricultural landscapes is important. In particular, the authors focus on coffee farms and the degree to which eight different farms across Jamaica vary in percent shade cover over their respective stands of coffee bushes.

Birds and canopy cover were sampled at each site during the winter months of 2010-2011 and 2011-2012. 298 mist-net captures produced 14 species of migratory warblers, the most common being Black-throated Blue Warbler, American Redstart, and Prairie Warbler. Canopy cover ranged from 0 to 89% with a mean of 56.7%. Spidal and Johnson found that across all species, there was a significant correlation between proportion male and percent canopy cover, with positive correlations occurring in each of the three common warbler species. This suggests that segregation between sexes may be occurring within a single habitat along a gradient of habitat quality, which may be explained by superior food availability available to insectivorous warblers existing higher in the canopy compared with that found in the coffee bushes below. The authors intend this work to set the stage for additional studies testing for whether the degree of sex class segregation of migrant warblers can be indicative of habitat quality on coffee farms.

We want to conclude by taking the opportunity to thank the greater Caribbean ornithological community for giving the Journal of Caribbean Ornithology another great year of contributions. To all of the researchers, reviewers, and other contributors – thank you for all of the hard work you do. Your time, energy, input, and feedback are what collectively build the JCO into a stronger peer-reviewed publication.
