A Year in the Life of a Lesser Yellowlegs

Laura McDuffie, a wildlife biologist for the U.S. Fish and Wildlife Service Migratory Bird Management Program, has been tracking the movements of Lesser Yellowlegs on their migration. Find out more about Laura’s work, the amazing journeys that Lesser Yellowlegs make each year and the threats they face along the way! Scroll down to see Laura’s webinar on the Lesser Yellowlegs with much more information on her research. Also check out our NEW short video on Lesser Yellowlegs and hunting in the Caribbean (below and on our YouTube).

Typically, when people think of shorebirds, they envision gangly, long-billed birds probing for invertebrates along sandy or rocky coastlines. But this is not where you are likely to find our study species, the Lesser Yellowlegs! This medium-sized shorebird breeds in the boreal forests of Alaska and Canada. They can be found in a diversity of wetland habitats during migration and overwintering in the Caribbean and Central and South America. This includes salt, brackish, and freshwater ponds and swamps, mud flats, mangroves, and other water edges. They are particularly fond of freshwater swamps and may also be found in large numbers on flooded agricultural fields (especially rice fields) if available, as in Suriname, Cuba, and Trinidad.

Shorebirds in Trouble

Over the past five decades, shorebirds have declined at an unprecedented rate. Factors causing this decline include habitat destruction and alteration, agrochemical applications, climate change, and for some shorebirds, including the Lesser Yellowlegs, unsustainable harvest at several non-breeding locations. Harvest occurs as sports hunting in the Caribbean, as well as hunting and trapping for sale as food, as a source of income in other parts of the flyway. Lesser Yellowlegs populations have declined by an alarming 63 ̶70% since the 1970s!

Keeping Track of Lesser Yellowlegs

In May 2016, the U.S. Fish and Wildlife Service Migratory Bird Management Program began deploying tracking devices (light-level geolocators) on breeding Lesser Yellowlegs in Anchorage, Alaska. Our goal was to determine where the species occurs during the non-breeding season. In 2017, birds returned to the breeding sites. To our dismay, however, they were incredibly difficult to recapture so that we could retrieve the tags and the data. This serious predicament ultimately made us have a “rethink” about our objectives for the Program. As a result, we expanded the range of our study to include collaborations with Kanuti National Wildlife Refuge, Alaska; Yellowknife, Northwest Territories; Ft. McMurray, Alberta; Churchill, Manitoba; James Bay, Ontario, and Mingan Archipelago, Quebec.

During the summers of 2018-2021, partners at Alaska Department of Fish and Game (Katherine Christie), USFWS (Christopher Harwood), Environment and Climate Change Canada (Jennie Rausch, Christian Friis, and Yves Aubrey), and Trent University (Erica Nol) deployed Lotek wireless GPS pinpoint tags on breeding adults. These tags record data via satellite so recaptures are not required! The GPS tags are accurate to ~10m, which has allowed us to examine the occurrence of Lesser Yellowlegs in countries where shorebirds are harvested. Since 2018, we have successfully deployed 115 GPS tags on Lesser Yellowlegs!

Amazing Journeys Revealed

Each bird we tag and release has their movements tracked, which mean we can identify the different countries they visit and specific sites they use during migration and overwintering. This information can help us to identify the potential bottlenecks and threats that birds experience each year.

Here is just one amazing journey made by “JP” who was tagged in Anchorage, Alaska in 2018. The tag revealed that he travelled at least 10,576 km on his southward migration, taking in Alberta and Manitoba, Canada, and Devils Lake, North Dakota, on his way through North America. JP then spent a whole month on Barbuda! This highlights how important the Caribbean can be as a rest and refueling spot for some shorebirds. Finally, JP made it to Middenstandspolder, in Suriname, where his tag went offline in February 2019.

We don’t know why JP’s tag stopped transmitting. It was not uncommon in our study to have incomplete tracklines. For these birds, the battery of the tag may have failed, or the harness could have fallen off and left the tag lying covered in mud, unable to recharge and transmit. However, we do know that some birds don’t survive the long journey.

Thanks to strong collaborations with biologists working in the Caribbean, we were able to receive some shorebird harvest reports. In fall 2020, we learned that two of our tagged birds “O2A” and “A65” were shot by hunters in Guadeloupe and Martinique, respectively. This shows that hunting isn’t only a “predicted threat” to the birds we studied, but also a real and observed threat.

Globally, Lesser Yellowlegs are in steep decline, with likely only 400,000 individuals remaining. Our research on the species has helped identify several potential threats, but we still need to learn more about the hazards these birds face. So, we must rely on assistance from local biologists, managers, hunters, and the public in the Caribbean and beyond.

The proper management of a species ensures that it will be around for future generations to enjoy and utilize. Awareness and education about the species decline and an understanding of the threats it faces can go a long way! When the general public is aware of an issue, they are more likely to take actions. These might include helping to monitor birds, conserving local wetlands, or ensuring that hunting laws protect vulnerable species. They may even participate in scientific efforts, such as submitting shorebird harvest records to managers. Awareness, information gathering and partnerships are critical components in helping us to protect these unique shorebirds.

Laura McDuffie has been studying the breeding and migration ecology of Alaska’s shorebirds and landbirds since 2014. In spring 2021, Laura completed her master’s degree in biological sciences at the University of Alaska Anchorage. Laura’s thesis is entitled “Migration ecology and harvest exposure risk of Lesser Yellowlegs.”

This study would not have been possible without the tremendous efforts of our collaborators. Our gratitude goes out to the following people: Brad Andres, Yves Aubry, Erin Bayne, Christophe Buidin, Katherine Christie, Ken Foster, Christian Friis, Autumn-Lynn Harrison, Christopher Harwood, James Johnson, Kevin Kardynal, Benoit Laliberte, Peter Marra, Erica Nol, Jennie Rausch, Yann Rochepault, Sarah Sonsthagen, Audrey Taylor, Lee Tibbitts, Ross Wood, Jay Wright, and all the field technicians that helped with banding. Kristy Rouse, Cassandra Schoofs, and Brent Koenen with Joint Base Elmendorf-Richardson’s 673rd CES/CEIS supported the project from the beginning and were instrumental in the DoD’s recognition of lesser yellowlegs as a Species of Special Concern. Funding sources include the Alaska Department of Fish and Game, Bird Studies Canada; Environment and Climate Change Canada, the Smithsonian Institution; the 673rd CES/CEIS, U.S. Department of the Air Force; and the U.S. Fish and Wildlife Service.

Seabird Fest: Plans Develop for a Regional Caribbean Seabird Census!

Save the date for a workshop where we celebrate our successes and plan our future work together!

We all love seabirds: the soaring Magnificent Frigatebirds, the Boobies’ expert diving, the entrancing Tropicbirds. But…what is a Seabird Fest?

Well, it is a half-day workshop, hosted by the BirdsCaribbean Seabird Working Group (SWG) planned for Thursday, December 2, 2021, 12 to 3 pm EST. During this event we want to hear from you with brief updates from the islands on how the seabirds are doing. The SWG will learn more – and share more – on what is taking place across the Caribbean in terms of seabird monitoring and conservation. Be sure to REGISTER HERE!

The purpose of the Seabird Fest is more than information gathering and sharing, however, although that is important. The SWG plans to discuss ways forward for a Caribbean Seabird Census (CSC) programme, modeled on the successful Caribbean Waterbird Census (CWC). We hope to introduce the CSC in 2023!

Caribbean Seabirds

The Caribbean is home to over twenty species of seabirds, with many more visiting the region’s marine environment on a yearly basis. Understanding where seabirds breed, and in what numbers, is essential for determining the pressures that they may face. This, in turn, helps managers minimise threats to their populations. However, monitoring seabird populations within our suite of remote and inaccessible islands in the Caribbean is no easy task!

Although great strides have been made in recent years with monitoring populations on some islands (e.g., the Grenadines, Antigua’s offshore cays, Cayman Islands etc.), many islands have not been routinely surveyed, and population estimates that do exist are outdated. Furthermore, formal regional overviews of seabird population information are a decade old (see Seabird Resources). Considering the range of factors with potential to cause change in the marine and coastal environments around our shores, such as large-scale events like Hurricanes Irma and Maria in 2017, there is an urgent need to monitor seabirds.

The initial goal will be to update our knowledge on the status of and threats to seabird populations in the Caribbean. If repeated regularly, seabird surveys will go on to help conservation scientists and managers understand how seabird populations are changing over time in our region, supporting efforts to protect them. By forming partnerships among interested groups and individuals that monitor seabirds, we can better tackle the logistical challenges of surveying hundreds of islands and cays. For this, we need to get as many interested organisations, communities and individuals involved in the effort as possible!

Why count seabirds?

Understanding seabird populations and monitoring changes in the size and health of populations is extremely important for conserving them. On land, many breeding sites are under threat from coastal development, introduced predators, disturbance, and egging. At sea, seabirds contend with threats from fishing activities, pollution, climate change, and offshore development.

Monitoring colonies and understanding population trends is therefore more important than ever. While some Caribbean islands already have active seabird monitoring programmes in place, others are home to large populations of seabirds that are not currently monitored. As such, our Seabird Working Group is working hard to try and secure funding for this programme, which will allow for training, data collection, and community engagement, particularly on islands where there are gaps in capacity for these activities.

Be sure to register for the Seabird Fest here, and keep an eye on our Seabird Working Group webpages, listserv and facebook group in the coming months for updates on Seabird Fest! Our SWG co-chairs are also looking for help to plan the event, as well as other ongoing SWG tasks, so please get in touch with us if you are interested!

The Struggle is Real for the Bridled Quail-Dove on St. Eustatius

The Bridled Quail-Dove is a quiet, retiring bird. It has reason to be nervous, because it is facing a doubtful future on the Dutch-speaking island of St. Eustatius (Statia). Hannah Madden, a Terrestrial Ecologist in St. Eustatius, gives us an important update on how this special bird is faring.

Two years ago we shared the worrying news that the Bridled Quail-Dove population had suffered a significant decline on Statia. This was as a direct result of the powerful and destructive Hurricanes Irma and Maria, which followed each other closely, in September 2017. Four years on, has the situation improved?

The Bridled Quail-Dove (Geotrygon mystacea) is a ground-dwelling species that is endemic to the Caribbean. It spends its day foraging in the forest understory for fruits, seeds and the occasional gecko. Quail-Doves prefer undisturbed forests with a closed canopy. They are very sensitive to changes in their natural habitat. And those changes are happening. Unfortunately the impacts of human-induced climate change mean more intense and more frequent hurricanes, which could spell trouble for this vulnerable species.

The Quill – Before and After

I began surveying Bridled Quail-Doves in the Quill National Park in 2016. The Quill is a dormant volcano that rises to 600 meters with a large, accessible crater. It is the dove’s only home on Statia. Pre-hurricane, Quail-Doves were relatively common and observant birders could almost certainly spot one or two while hiking along the trails. The species breeds in May, when its mournful and unmistakable ‘whooooos’ can be heard echoing through the forest.

Then came Irma and Maria. In September 2017 the forest habitat of the Quill suffered extensive damage from the back-to-back hurricanes. Trees were stripped of leaves and fruits, branches were broken. Some trees did not survive. The hurricanes have left their mark – you can still see the evidence in some parts of the forest.

Then there are the goats!

In addition, we have a very serious goat problem in the park—one that has been pervasive for decades. These are non-native, free-ranging goats that graze excessively in areas that are already damaged. This results in a limited food supply and reduced understory cover for the Bridled Quail-Dove (as well as other species that depend on the forest). There is nowhere for the birds to find food and shelter. Feral chickens disturb ground cover and compete for the same food source. Invasive black rats and feral cats, both of which are present in the Quill prey on nests and take eggs and chicks. The Bridled Quail-Dove’s survival rate – and its chances of bringing up a family – are slim. There is no evidence that adult birds have come in from nearby islands. The Bridled Quail-Doves of Statia are physically and genetically isolated. We became concerned for the welfare of the Bridled Quail-Dove. We were grateful for the funds from many generous donors, including BirdsCaribbean, allowing us to conduct our surveys.

In search of the Quail-Dove

I conducted surveys of the Bridled Quail-Dove in the Quill National Park, walking previously established transects (walking routes) within the dove’s range (~150 to 600 m). We surveyed during peak breeding season (May), so that we could hear as well as see the birds. Once I saw or heard a Quail-Dove, I measured the distance to the bird. I also recorded how high up they were, and the height of the forest canopy. Once surveys were complete, I pooled all data from 2016 – 2021 to obtain abundance and density estimates per year.

Greater effort, disappointing results

As shown in the graph below, we increased the extent of our survey from 1,200 m of transects in 2016 to over 15,000 m in 2021. Our coverage increased 13-fold, and yet we were able to find only around one third of the number of doves that were counted in 2016, before the hurricanes. It was challenging work. As you can imagine, repeating so many surveys is physically demanding.

Graph showing Quail Dove detections — Number of detections (left axis; red line) and survey effort (right axis; blue line) between 2016 and 2021 (no surveys were conducted in 2020).

Unfortunately, estimates of the numbers of Bridled Quail-Dove on St. Eustatius have declined significantly since 2016. The current estimate is just 123 individuals (somewhere between a minimum of 72 and a maximum of 210). This is less than half of the 2019 estimate, and less than 5% of the 2016 estimate. So, numbers have continued to dwindle since the hurricanes.

After assessing the influence of covariates (factors that might influence the presence or absence of the dove, like weather, time of day, elevation, condition of the vegetation, etc.) on Bridled Quail-Dove presence, I found that doves were more likely to be found at higher elevations in habitats with a higher canopy (such as inside the crater, along the rim, and on the upper outer slopes of the Quill). It became clear also that in the years following hurricanes Irma and Maria, doves were less and less likely to be present in the survey area.

Urgent action is needed to save the Bridled Quail-Dove on Statia!

We are extremely worried about the Bridled Quail-Dove on St. Eustatius. This lovely bird’s ongoing decline is caused by a combination of two factors: the destruction of the places it calls home, and the invasive species that prey on it. Its long-term survival is now uncertain unless urgent action is taken to save it. Even if the dove does keep going, such a small and isolated population faces additional risks, such as inbreeding.

Climate change is here to stay, and this means that hurricanes are likely to become more frequent and more powerful. This could be catastrophic for the Statia population, and others in the region. Recently the International Union for the Conservation of Nature (IUCN) proposed that the conservation status of the Bridled Quail-Dove be reassessed, based on our work on Statia. This means the classification could be changed from Least Concern to Near Threatened or Vulnerable. However, apart from Statia, data are still lacking from many islands. We encourage enthusiastic birders to conduct their own surveys so that local populations can be evaluated.

An Action Plan for a precious bird

We will be working with local conservation NGO St. Eustatius National Parks (STENAPA) to create an Action Plan for the Bridled Quail-Dove. To effectively protect the species locally, it is likely that we will have to take action on several fronts, Goats, cats and feral chickens will need to be removed from the park and rodent will need to be controlled. For this, we will need the support of the local government and the community.

Monitoring Bridled Quail-Doves on Statia is a tremendous effort. To make life easier, we are suggesting trying out passive acoustic monitoring (PAM) devices during the breeding season. How does this work? Recording units can be placed in the field for up to a month to record and interpret calls. Using these devices will allow us to collect data in less accessible areas, helping us to broaden our study.

The work will continue as we seek to find help for this iconic bird. Hopefully, by combining conservation efforts with field surveys and PAM, we will have better news in the coming years.

Thank you to BirdsCaribbean and all the generous donors who supported BirdsCaribbean’s Hurricane Relief Fund – my survey work on the Bridled Quail-Dove would not have been possible without your support!

Passing the Torch to a New JCO Managing Editor

Outgoing Journal of Caribbean Ornithology (JCO) Managing Editor, Justin Proctor, shares the exciting news that Dr. Stefan Gleissberg is the new Managing Editor of JCO. Stefan is no stranger to JCO, as he’s been with the journal since 2019, first in the capacity of Assistant Production Editor, and then as Production Editor. His knowledge of our journal, dedication to its mission, and kinship with our staff makes him a great fit for leadership within the JCO family. Learn more about Stefan below!

In 2016, it was decided that the Journal of Caribbean Ornithology (JCO) could benefit from the creation of a new role: a Managing Editor. The behind-the-scenes of JCO looked very different then, with just a handful of amazing volunteers working overtime to keep everything afloat. And so when the Editor-in-Chief at the time, Dr. Jason Townsend, reached out to me to gauge my interest in the position, I was excited to accept the offer, join the team, and figure out how best to help.

I ended up making the decision to focus a lot of my effort over the following years on building up a bigger team. We simply needed more hands on deck to ensure a more timely and quality product, and to give JCO the personable touch that we wanted to have. I’m happy to say that those efforts have borne fruit: JCO has gone from an all-volunteer team of ~6 individuals to a team of 10 part-time paid staff and 17 volunteers. Now, thanks to all of these amazing staff and the quality work they produce, JCO has an extensive list of achievements and publications to be very proud of. From submission through to publication, this team has become a cohesive unit that goes above and beyond to support our authors, reviewers, and each other—each and every step of the way. The added capacity has also allowed us to build out other elements of JCO. This will ensure the journal has the foundation and adaptability to remain the #1 ornithological journal in the Caribbean far into the future. I’m feeling really good about the road ahead.

The time has come, however, for me to pass the Managing Editor position into new hands. As much as I’m going to have a hard time letting go of it, I think it’s a healthy move for the journal. What’s exciting is that the change-up will allow me more time to serve the journal’s needs through my Vice-President Executive Board position with BirdsCaribbean, albeit more from the background. We are at an unprecedented time in which the JCO has two representatives on the BC Board of Directors, including me and our Editor-in-Chief, Dr. Joseph M. Wunderle, Jr. This is a great opportunity to build even more positive momentum.

During our preliminary search for a new Managing Editor, we were pleasantly surprised when one of our own staff members expressed interest in the position. We were excited to first pursue that possibility before advertising the position more broadly. And so we did pursue it, and couldn’t be happier with how things turned out. On behalf of the BirdsCaribbean Board of Directors, Joe, and myself, I am excited to announce that Dr. Stefan Gleissberg will be stepping up into the role of Managing Editor. Stefan is no stranger to JCO, as he’s been with the journal since 2019—first in the capacity of Assistant Production Editor and then as Production Editor. His knowledge of our journal, dedication to its mission, and kinship with our staff makes him a great fit for leadership within the JCO family.

Stefan’s previous career as an international researcher in the plant sciences afforded him intimate familiarity with the world of scientific publishing. He has served both as author of peer-reviewed articles and book chapters, and as peer reviewer of manuscripts for academic journals and book publishers. A life-long birder, Stefan decided to re-engage in bird conservation and the birding community after retiring from his career in plant biology. In 2014, Stefan founded the Athens Area Birders in Ohio, a local community engaged in nature education and birding, and joined the Board of Directors of the Athens Conservancy, a land trust. He currently serves as Vice-President of the Ohio Ornithological Society, as steering committee member of the Ohio Bird Conservation Initiative, and as a statewide eBird data reviewer for Ohio, among other roles. From 2015 to 2020, Stefan served as the editor of The Cerulean, a print/online newsletter-magazine of the Ohio Ornithological Society. For this member-centered publication, he oversaw all aspects from acquisition, editing, layout, photo-editing, and production. He also contributed editorials and articles. And his more recent work with JCO has immersed Stefan into the world of Caribbean birds, a place where I know he’s excited about spending a lot more time.

Thank you to everyone for your ongoing support of the Journal of Caribbean Ornithology. It’s a one-of-a-kind journal that we are fortunate to call our own. To Stefan, I wish you great success in your new position as Managing Editor. It’s a lot of fun, no doubt about it. And while I can’t promise it will be all rainbows and butterflies, I can promise a lot of palm crows and raucous cries!

All the best,

—Justin Proctor

Editor’s note: We thank Justin Proctor for his incredible service and hard work to build the JCO team and make journal the successful peer-reviewed publication that it is today, and we extend a warm welcome to Stefan.

p.s. The Journal of Caribbean Ornithology is in need of financial support! If you are able to make a one-time donation or become a monthly sustainer, know that your gift would be helping to building capacity for science and conservation of Caribbean birds, a core part of our vital mission.

Birds in Every Shape and Form—Morphological Diversity in Grenada and Across the Caribbean

Did you know that the same species of Caribbean birds can be a bit different on each island? Find out more from Nicky Koper, who visited Grenada with her team, to compare the Grenadian birds with those across the Caribbean.

Every island in the Caribbean has its own feel, vibe, and ultimately, its own ecosystems. It is not surprising, then, that the Caribbean’s bird communities have adapted a little differently to every island they are found on. This makes each island population genetically and ecologically distinct. Our team from the University of Manitoba and Oak Hammock Marsh Interpretive Centre (in Manitoba, Canada) wanted to learn more about why this happens.

Recently, the team published two papers highlighting how and why birds on different Caribbean islands are distinct from one another. We paid special attention to land birds of Grenada, because to the best of our knowledge, the unique forms and structures of land birds here have only been studied in depth for one species before (Bananaquits, by Dr. Joseph Wunderle). While we collected lots of primary data from Grenada in our field trips there, these papers represent one of those special projects that really came about through collaborations with and contributions from many scientists, who generously contributed their data from other islands (and Venezuela) to enable this research (see our thank-you*, below!).

Although we caught 19 species in Grenada in mist-nets from 2015 to 2017, we focused our analyses on just 4 of these, for which we had lots of data (> 400 individuals per species) from Grenada and other islands: Bananaquit, Black-faced Grassquit, Lesser Antillean Bullfinch, and Common Ground Dove.

Personally, I found our results extremely interesting, as we found many differences between the populations on Grenada compared with other islands, as published in our recent Journal of Caribbean Ornithology paper. In fact, every one of the 4 species we studied on Grenada differed in at least one way from every other population we studied. In a few cases, the Grenada populations were exceptional; for example, Lesser Antillean Bullfinches were smaller on Grenada than anywhere else, while Common Ground Doves had longer tarsi (lower leg bones) than any other population.

Black-faced Grassquits had relatively long wings on Grenada compared with other islands. (Photo by Paulson Des Brisay)

We also really wanted to find out what might have contributed to the unique adaptations of these species across the Caribbean. In our paper in the journal Ornithology, we show that islands with lower avian diversity have populations with characteristics suggesting evidence of “ecological release” – on islands with fewer species, there is less competition among species, which allows for that population to use a wider variety of habitats or niches. This, in turn, tends to result in morphological characteristics that help birds to successfully use a wider variety of resources.

While ecological release seems to be the most important single driver affecting evolution of physical traits in the species we studied, it’s definitely not the only one. Grassquits had longer wings and ground doves had longer tarsi on islands with mongoose, which might mean that these species have begun to adapt to the recent increase in predation risk from that animal. The stronger they can fly or lever off of the ground, the better they can escape mongoose. Morphology of several species also varied with climatic differences among islands.

We think the key take-home messages from this research are that Grenada’s bird populations – and indeed, the populations on all the Caribbean islands – are ecologically unique. Our conservation and management of these islands shouldn’t focus just on species that are endemic; we also need to recognize that each island population contributes to the diversity of its species, so we really need to conserve the species on every island on which they occur.

Flock together with us this August for the AOS 2021 Virtual Meeting! The meeting, August 9-13, features a fantastic line-up of keynote and plenary speakers, workshops, symposia, discussions, and social events. The meeting theme, Birds of Many Feathers Flock Together, aims to harness the power of all the individuals who study, conserve, and educate about birds. BirdsCaribbean is excited to be a part of the meeting through several events, including a symposium, and a meet and greet social hour. Mark your calendars, be sure to register, and read more about these events below!

BirdsCaribbean Symposium Will Showcase Caribbean Research and Conservation

On August 11th and 12th, BirdsCaribbean will host a three-part symposium entitled, “Resilient Caribbean Birds—Surviving and Thriving in a Challenging World.” This symposium will highlight lessons learned from recent avian research and conservation projects in the Caribbean that focus on the resilience of birds and people to cope with numerous threats, including storms and hurricanes, invasive species, habitat destruction, and more. Sixteen ornithologists and conservationists will share their work and there will be time for Q&A and discussion. See the full abstract below; the AOS Meeting program and abstracts are available for download here.

Get Social with Us!

BirdsCaribbean will host a Meet and Greet Social Hour on Tues Aug 10 from 4-5pm EDT. We all miss live events and getting to catch up in person. We’re hoping you’ll join us on Zoom, where we can all grab our favorite Caribbean cocktails and see your smiling faces! Our Meet and Greet is a fantastic opportunity for BirdsCaribbean members to reconnect and for new recruits to meet some friendly colleagues. Come mingle with our amazing community and hopefully get inspired to learn more during our three-part symposium over the following two days. We’ll be starting out with some ice breakers (think favorite Caribbean bird and Caribbean cocktail), followed by a fun bird trivia quiz to test how well you know your Caribbean birds (studying encouraged!).

BirdsCaribbean Symposium Abstract: Resilient Caribbean birds: Surviving and thriving in a challenging world

Organizers: Lisa G. Sorenson and Adrianne G. Tossas

The insular Caribbean is recognized as one of the top five global biodiversity conservation hotspots, yet this important region’s wildlife face numerous threats, from destruction of habitats for development to more frequent and extreme weather events exacerbated by climate change. The region is of exceptional importance to birds, hosting 171 endemic species. It also serves as a key migratory route for more than 100 migrants, whose journeys between the North and South American mainlands depend on quality habitat throughout the islands. BirdsCaribbean and its wide network of partners across the Caribbean have recognized that in order for birds and their habitats to survive and thrive during these times of rapid change, conservationists and communities must share resources, collaborate, and flock together to stem the tides of avian loss.

During our symposium, members of the BirdsCaribbean community—scientists, conservationists, students, and volunteers—will share their work and lessons learned on building resilience for the region’s resident and migratory bird species. The diversity of research and accomplishments showcased in this symposium is a testament to the region’s tenacious spirit, camaraderie, resourcefulness, and inherent passion for their natural world. It is also a testament to the resilience of birds, demonstrating that many species of birds can survive if we give them the chance to do so, by alleviating threats, protecting habitats, and engaging communities in conservation.

We are excited to announce that the David S. Lee Fund for the Conservation of Caribbean Birds will fund 9 projects in 2021! In the previous 4 years (2016-2020), the fund has provided assistance for 15 projects in 6 countries for work on dozens of species in the Caribbean.

This fund was created by generous donations from the family, friends, and collaborators of David S. Lee to continue his inspiring legacy of conservation in the Caribbean. You can help us to continue supporting these invaluable projects by making a donation here.

Congratulations to these exemplary researchers, and we look forward to hearing about your results in future blog articles and publications!

Investigating variation in cooperative breeding behavior between Puerto Rican Tody populations

Amber Wendler, Virginia Tech

Cooperative breeding occurs when some individuals, known as “helpers,” assist with raising their siblings, rather than reproducing themselves. This breeding strategy is used by many bird species, including the Puerto Rican Tody (Todus mexicanus). However, only some individuals of this species breed cooperatively, and differences are thought to be linked to habitat. Amber’s research will examine how the Tody’s cooperative breeding behavior differs in rainforest and dry forest habitats. By increasing our understanding of the Tody’s natural history, her work can help manage and conserve this endemic species.

Territory use of the Critically Endangered Bahama Oriole across the annual cycle

Michelle Moyer, University of Maryland Baltimore County (UMBC)

The Bahama Oriole (Icterus northropi) is a Critically Endangered species that is found only on Andros Island in The Bahamas. Thanks to recent work by the Bahama Oriole Project — a collaboration between UMBC and the Bahamas National Trust (BNT)— we have learned a lot about this species’ breeding habitat, including that it uses the native pine forest much more than previously thought. However, it is unknown how Orioles use the pine forest and other habitats outside of the breeding season. Using tiny, solar-powered transmitters (CTT Life Tags™ ), which will be attached to Orioles and detected by a central receiver (CTT Node), Michelle will track their movements throughout the full annual cycle. The results of her research will inform BNT’s conservation management strategies for the Oriole.

Caribbean psittacines as indirect controllers of ecosystem dynamics through commensal feeding associations and ecosystem engineering

Damion Whyte, University of the West Indies at Mona

Parrots and parakeets are notorious for not finishing the fruits that they open. As a result, they are often viewed as wasteful pests, and are feared by farmers. However, we do not have a great understanding of the impacts that this behavior can have on the local ecosystem, such as providing easier access to the fruit by other species and dispersing seeds. Damion’s research will quantify the ecosystem-wide effects of foraging by parrots and parakeets on the island of Curacao. Using observations and camera-traps, he will identify which species visit fruit that has been opened by, and how their behaviors vary. By providing insight into these species interactions, his work will support bird conservation and management in protected areas.

**Pre-reproductive survival, movements, and habitat use of the Yellow-shouldered Blackbird (Agelaius xanthomus) in Southwestern Puerto Rico**

Jean P. Gonzalez Crespo, University of Wisconsin

The Yellow-shouldered Blackbird (Agelaius xanthomus) is an Endangered species that is endemic to Puerto Rico. Although conservation measures such as artificial nesting structures increased the reproductive success of this species, populations have continued to decline. Using CTT Life Tag™ transmitters Jean will track Blackbirds after they fledge from the nest and estimate their survival during this critical period. His work will help local and federal agencies determine whether survival rates before breeding are contributing to population declines, and identify the factors that influence survival.

Establishing a long-term banding program for migratory birds in Isla Contoy National Park, Mexico

Jonathan Nochebuena Jaramillo, Estación de Anillamiento Parque Nacional Isla Contoy

Isla Contoy National Park (PNIC) is a small Caribbean island (238 hectares) near the Yucatan Peninsula in Mexico. The island is an important site for many migratory birds to rest and refuel on their long journeys between North, Central, and South America. In 2019, Jonathan personally initiated a banding program in PNIC. He will continue and expand this program to document and spread awareness of the importance of the island for a wide diversity of birds, and provide information to conserve birds and their habitats on the island.

**Understanding nestling diet composition of Roseate Terns (Sterna dougallii) through fecal DNA Metabarcoding**

Luis Ramos, University of Puerto Rico, Mayaguez

Environmental changes such as rising sea temperatures and ocean acidification pose many threats to seabirds and the marine food sources that they depend on. The Roseate Tern (Sterna dougallii ) is a species of conservation concern in the Caribbean, including in Puerto Rico. Yet we know little about foraging behavior, ecology, and population trends of this species. Luis’s research will use an advanced molecular method (DNA metabarcoding) to assess the diet composition of chicks in Tern populations on the southern and northern coasts of Puerto Rico. His work will identify the fish and other prey that are available to Terns in different colonies, and advance our understanding of DNA metabarcoding as an important biomonitoring tool.

Evaluating the effects of greening actions on avian diversity on tropical urban landscapes

Julissa Irizarry, Penn State University

Expansion of urban areas contributes to loss and fragmentation of habitats across the globe. These drastic landscape changes can negatively impact biodiversity, especially on islands. Large-scale tree planting efforts, such as those planned in Puerto Rico following Hurricane Maria, have the potential to increase the suitability of urban areas for native wildlife. Julissa’s project will investigate the benefits of urban reforestation for resident and migratory birds. Using an experimental approach, she will compare how birds use newly planted trees—“functional” tree species that are known to be important for foraging and “structural” plants that are traditionally used for landscaping. Her work will inform best practices for implementing urban greening projects in order to maximize conservation benefits.

Current status of the breeding colonies of Red-footed Booby, Brown Booby, and Masked Booby in Los Roques Archipelago, Venezuela

Josmar Esteban Márquez, AveZona / BirdsCaribbean / Fundación Científica ARA MACAO / PAAVe

Los Roques Archipelago National Park is in the Caribbean Sea 130 km north of Venezuela. It has 42 islets and 200 sandbanks arranged around an internal lagoon. It is home to all the typical ecosystems of tropical maritime and coastal areas: sandy beaches, coral formations, salt and brackish water lagoons, seagrass meadows, and mangroves. This archipelago was declared a National Park in 1972, and its Use Regulation and Management Plan was finalized in 1990. Los Roques is home to a great diversity of seabirds and is a priority area for conservation. Conserving seabirds in the Caribbean is essential, as their numbers have been decreasing over time. Documenting their status and trends is needed to develop conservation plans. Two species of boobies have breeding colonies in Los Roques: Red-footed Booby and Brown Booby. Masked Booby’s presence has been documented, but their reproduction has not been confirmed. 20 years have passed since the last assessment of the population of seabirds in the Los Roques Archipelago. Since then there have been many political, economic and environmental changes in Venezuela—changes that may put the Los Roques Archipelago and the booby colonies at risk. We propose to survey and evaluate the reproductive colonies of boobies in 4 keys of the archipelago. We will also explore other cays to look for confirmation of breeding activity. We will integrate the local “Roqueños” communities in the censuses and outreach activities.

**Population dynamics, conservation and management of the American Flamingo (Phoenicopterus ruber) on Margarita Island, Venezuela**

Anahy Marcano , INPARQUES / AveZona / PAAVe

Venezuela has about 38% of the total population of American Flamingos, Phoenicopterus ruber. It is considered a resident species on the Isla de Margarita in Venezuela. Although its population has shown variations in size and distribution, historically, American Flamingos have been observed on the Isla de Margarita since the beginning of the last century. Recently, a new flamingo nesting area has been identified on Margarita Island in the Laguna de las Marites Natural Monument. However, its population status is unknown and currently there is no plan for its conservation and management. As the first stage of this project we will estimate the size of the breeding population, the reproductive success, and the demographic parameters in two of the nine areas occupied by the American Flamingos on Margarita Island, las Marites Lake Natural Monument and La Restinga National Park. Visual observations will be conducted from a safe distance so as not to disturb the breeding areas. After the breeding season, the area used for the nests will be evaluated. As part of this project, we will involve local communities in the censuses and an educational campaign will be established.

The David S. Lee Fund for Conservation seeks to continue David’s passion for protecting wildlife. The fund supports direct, innovative conservation work in the Caribbean Region for birds and their habitats. The fund is managed by BirdsCaribbean and used for annual small grants.

Lessons from the Louisiana Waterthrush: How Water Quality Affects the Survival of a Small Migratory Songbird

The Louisiana Waterthrush is a neotropical migratory warbler that links North America, where it breeds, to the Caribbean, where is spends the winter. Steven Latta PhD has worked on this species for more than a decade. Here he shares some fascinating insights into how water quality impacts the health and survival of this small bird, and what this means for people as well as birds.

Clean water is something that is essential to each and every one of us. There is, however, a rising tide of water quality threats facing Neotropical migratory birds – both in their North American breeding grounds and their Caribbean wintering spots. Water pollution and water diversions can wreak havoc on the quality of the water that supports plant, animal and aquatic life. This also negatively impacts the health and welfare of humans who also depend on that water resource.

I have used a migratory songbird, the Louisiana Waterthrush, for more than a decade to monitor changes in water quality, and to understand the impacts of water quality on birds and other life that depend on riparian ecosystems – that is, rivers, streams and wetlands.

Although somewhat reminiscent of a thrush, the Louisiana Waterthrush is actually a large, mostly terrestrial warbler. It is uniformly dark olive-brown above and white below, with dark brown streaks on its breast and sides, and flanks washed buffy. Distinctive field marks include a white supercilium (eyebrow stripe) which flares and broadens behind the eye, and an unspotted white throat. In both its breeding and wintering grounds, the waterthrush inhabits freshwater streams and associated riparian vegetation in forested hills and mountains. The Louisiana Waterthrush is considered a Species of Conservation Concern in several Bird Conservation Regions. Its dependence on a specialized habitat, now threatened by a number of environmental stressors, makes the species more vulnerable.

Waterthrush Warnings

Long-term studies in Pennsylvania and the Dominican Republic have sought to understand the role of water quality and other factors in determining the population size of the Louisiana Waterthrush

In the Caribbean, Louisiana Waterthrush are solitary and territorial. They forage mostly on the ground by walking in a deliberate manner along the water’s edge, jumping over obstacles, characteristically bobbing and teetering, as they capture aquatic insects and similar prey.

I have worked closely with my colleagues, Danilo Mejía and Maria Paulino, from the Dominican environmental organization, Grupo Acción Ecológica, in a long-term study of this charismatic species. Every year, our work has taken us from studies in wintering areas in the Cordillera Septentrional of the Dominican Republic, to research in the breeding grounds in the Laurel Highlands of Pennsylvania.

At both ends of the annual cycle, we have shown how the waterthrush can serve as a warning sign, pointing to the deteriorating condition of waterways, and the presence of toxins and harmful chemicals. In areas where the bird breeds such as Pennsylvania, water quality is affected by acid precipitation, acid mine drainage from abandoned coal mines and agricultural run-off. Most recently. metals associated with hydraulic fracturing for natural gas deposits have impacted the condition of the fresh water. On the wintering grounds, the sites we visit suffer adverse effects from sedimentation and run-off from agriculture and human settlements.

Water Quality: A Critical But Deteriorating Factor

By tracking nesting, breeding success, and survival of individual birds, we have been able to quantify the impacts of reduced water quality. Contamination may directly impact the Louisiana Waterthrush. For example, we have shown that because of its position at the top of the food chain along rivers and streams, the waterthrush will accumulate within its body the metals associated with hydraulic fracturing of deep shale layers for natural gas. Studies with our collaborator, Mack Frantz, have further suggested that this shale gas development may even result in epigenetic effects on gene expression in waterthrush. This means there may be changes in the genetic structure itself that may affect long‐term population survival and fitness.

But reduced water quality can also have more subtle effects on birds. For example, Louisiana Waterthrush that nest on acidified streams are fewer in number and hold larger territories, presumably because they need more space to find enough food. Notably, the birds in contaminated areas delay nesting, producing fewer, smaller chicks, and fewer of these nesting adults return to the same stream the following year. These results suggest that waterthrush suffer pronounced declines in populations as the result of poor water quality.

A similar situation exists on the Caribbean wintering grounds. Louisiana Waterthrush on lower quality streams require longer territories, and pass the winter in poorer body condition. Fewer birds from low quality territories return the following year as compared to high quality territories. This suggests that reduced water quality in wintering grounds also reduces the birds’ survival rates.

How Does Poor Water Quality Affect the Birds?

Collaborating with two graduate students, we have been able to show why water quality affects Louisiana Waterthrush so dramatically. Brian Trevelline and Brandon Hoenig have combined traditional habitat sampling with advanced molecular techniques such as DNA metabarcoding of feces to analyze diets. They have demonstrated that when water quality declines with increased acidity or other contamination, the availability of preferred aquatic insect prey, such as mayflies, declines. The waterthrush compensate for this by altering their typical aquatic foraging behavior and diet. They venture further away from the stream to consume more terrestrial prey such as crickets, moths and spiders.

While these findings suggest that migrants may be able to adapt to environmental degradation, such behavioral changes may carry additional costs. Alternative food sources may have less nutritive value, resulting in physiological impacts on nestlings or adults. The breeding season is one of the most energetically demanding periods for birds; flying further away from the nest in search of alternative food in unfamiliar places could incur physiological costs. Moreover, it makes the predation of eggs, nestlings, or even adult birds more likely.

“You Are What You Eat:” The Waterthrush’s Evolving Diet

On the Dominican wintering grounds we also found shifts in diet among the streams that form the birds’ habitat. The diet of Louisiana Waterthrush in the Caribbean consists of fewer aquatic prey species and more terrestrial beetles, flies, and caterpillars. While the wintering waterthrush appears to feed on a wider range of species, these data suggest that on the wintering grounds, it is more of a dietary generalist. This highlights the importance of studying birds across their entire annual cycle to better understand their ecology and conservation needs.

These changes in the birds’ diet, which depend on the quality of habitat and the seasons, have vitally important consequences. On the breeding grounds, we have shown that nestlings from high quality streams that feed largely on mayflies grow faster and larger, and this has survival consequences. On the wintering grounds, variation in diet is also thought to impact survival. We showed that birds occupying higher quality territories with better food resources achieve a better body condition (i.e., they gain more muscle and fat) during the overwinter period. Body condition, in turn, was important in determining whether birds return the following winter, with the healthier birds returning at higher rates.

Good Quality Fresh Water: Important for the Birds, and Humans Too

This body of work links water quality to availability of preferred food resources. Our findings provide linkages among events during the breeding season and the overwintering period that affect the birds’ physiological condition, reproductive success, and annual survival. These studies show that changes in water quality from human activities, impacting the aquatic creatures that form the birds’ diet, can carry over across seasons. These changes accumulate over more than one life-history period, before manifesting themselves in a pattern of reduced survival.

Taken together, these studies emphasize the critical importance of water quality as it affects aquatic insect prey and as a result, impacts Louisiana Waterthrush at both ends of its annual migratory cycle. However, water quality also affects human communities. This is a message we have communicated through annual summer fairs and other activities in rural communities near our Dominican stream sites. Clean water is something that is essential to each and every one of us; we are pleased to be using birds as a tool, helping to protect watersheds and water quality across the range of the Louisiana Waterthrush.

Taking a Look at Shorebirds in Trinidad: A Population Update and Testing a New Survey Method

Trinidad and Tobago has a rich abundance and diversity of shorebirds and provides vital habitats for them during migration and over winter. Martin Gebauer, the recipient of a small grant for work on shorebirds from BirdsCaribbean, gives us a historical perspective and an update on shorebird populations and their habitats on the island of Trinidad. Find out from Martin if using drones can help us to count and monitor shorebirds.

TAKING A DEEPER LOOK AT MIGRATING SHOREBIRDS IN TRINIDAD AND TOBAGO

Arctic-nesting shorebird populations have shown serious declines on breeding grounds, and at staging and wintering areas across their range. The US Fish and Wildlife Service (USFWS), Canadian Wildlife Service (CWS), BirdsCaribbean (BC), and others have been looking into threats – including hunting – to shorebirds in the Caribbean through the Atlantic Flyway Shorebird Initiative (AFSI). It is clear, however, that more research is needed on the abundance, diversity, distribution, and habitat use of shorebirds migrating through or wintering in Trinidad and Tobago (TT), as well as the location of staging and wintering areas in the country. To support the AFSI, shorebird surveys (including the use of a drone) were conducted from 2018 to 2020. To determine the scale of shorebird declines, survey data were compared to data from aerial surveys on fixed wing aircraft conducted by Morrison and Ross (CWS) in 1982. The current work was supported by the USFWS and BirdsCaribbean.

THE RICH DIVERSITY OF TRINIDAD AND TOBAGO’S SHOREBIRDS

Shorebird diversity in Trinidad and Tobago is particularly rich. Of the 48 shorebird species recorded to date, some of which are European vagrants, 23 species were observed during the 2018 to 2020 surveys. Our surveys, and those by Morrison and Ross and others, found that the Semipalmated Sandpiper is by far the most common species, representing around 90% of shorebirds tallied in the country. Other common species are Western Sandpiper (see photo), Semipalmated Plover, Lesser Yellowlegs, Stilt Sandpiper, Whimbrel, and Willet. Historical accounts suggest a similar mixture of species

SADLY, SHOREBIRDS IN DECLINING NUMBERS

The February 1982 aerial survey of Trinidad by Morrison and Ross documented more than 13,600 Nearctic shorebirds. But there is worrying news. The maximum number of birds seen on the 2018 to 2020 surveys was 4,174 (September 2018). This disturbing decline, which is described in more detail below, matches up with the USFWS and CWS findings. Although an accurate estimate of the percent decline is difficult, current shorebird populations are likely only between 20 to 30% of 1982 levels.

WHERE WERE WE LOOKING FOR SHOREBIRDS?

Some of the most important habitats for shorebirds are on the west coast of Trinidad. In fact, the west coast mudflats are designated as an Important Bird Area (IBA) by Birdlife International. The area between the southern end of Caroni Swamp and south past the Couva River mouth to around Pointe-à-Pierre seems to be particularly good for shorebirds. Where the mudflats look greenish in color, there is a thick slurry of biofilm (i.e., diatoms, bacteria, organic detritus, and benthic invertebrates), a very important food source for Semipalmated and Western sandpipers. Morrison and Ross found that about 99% of all shorebirds observed on their aerial surveys were on the west coast mudflats, which aligns with the approximately 95% of shorebirds documented from 2018 to 2020. Very few shorebirds have been observed on the northern, eastern, or southern coasts.

Another important area for shorebirds is the Caroni Rice Fields. Regrettably, since 2003, rice farming has been abandoned in large portions of these fields and the overall habitat for shorebirds has declined. However, in some years – for example, in 2020 – large numbers of shorebirds can still be found here.

WHAT DID THE DRONE SURVEYS SHOW?

The drone surveys provided an excellent overview of habitats at each of the sites surveyed. Unfortunately, because the images were not sufficiently high resolution, a detailed analysis of shorebird use, whether manual or software-driven, was not possible. Another challenge was that birds were disturbed and often flew away, even when the drone was at a height of 100 m. We did find that drones may be suitable for surveying larger species such as gulls, skimmers and terns, as shown in the adjacent picture (Brickfield, 40m, 05 April 2020).

ARE SHOREBIRDS LOSING THEIR OLD HANGOUTS?

The area with the highest shorebird numbers during the 1982 Morrison and Ross surveys was the Point Lisas industrial development (see photo). However, currently this area is not accessible by foot or drone. Nevertheless, a review of recent aerial imagery suggests that habitats in this area have been dramatically altered through dredging and land reclamation activities.

Apparently, this loss of the mudflats that provide so much food and foraging for small shorebirds (Semipalmated and Western Sandpipers) appears to be a cause of the considerable declines of these charming, once abundant little birds between the 1982 and the 2018-2020 surveys.

Following the construction of the Orange Valley fishing pier, there has been a dramatic decline in the surrounding mudflats, with a rapid expansion of mangroves in the area.

There are local factors that are contributing to the declining numbers of shorebirds in Trinidad. Previously rich areas where they foraged for food are disappearing. In some areas, an increase in mangrove growth has affected the mudflats that shorebirds love. We must also take into account the global picture; across the flyway shorebirds are declining. What lessons can we learn from other countries? One thing is clear: To ensure that these losses of habitats for the wintering shorebirds do not continue in Trinidad, protecting and restoring remaining mudflat areas on the west coast of Trinidad has to be a critical goal in shorebird management.

This downward spiral has to be slowed or better still, turned around.

Martin Gebauer is an ornithologist and president of Gebauer & Associates Ltd., an environmental consulting firm. He is currently working on his PhD at the University of Oxford. He carried out research on shorebird hunting in the Caribbean for his MSc from Oxford.

David S. Lee (1943-2014) was a pioneering naturalist and conservation biologist who helped get BirdsCaribbean started nearly 30 years ago. He inspired many naturalists with his work and his writing. He was a man of many interests, and with respect to the Caribbean, published numerous papers and articles in the popular press on seabirds, Bahamian fish, turtles, snakes, bats, and orchids.

Donations from Dave’s wife, Mary Kay Clark and his mother, June Bash, allowed the establishment of the David S. Lee Fund for the Conservation of Caribbean Birds that will award money to conservation projects in his honor. The money is being held in a trust and will be used to award annual grants for innovative projects that protect Caribbean birds and their habitats.

Goal of the Fund: The David S. Lee Fund for Conservation seeks to continue David’s passion for protecting wildlife. The fund will support direct, innovative conservation work in the Caribbean Region for birds and their habitats. The fund will be managed by BirdsCaribbean and used for annual small grants. Applicants should demonstrate how their project will work with conservation groups and local communities in the Caribbean.

Eligibility: Scientists/naturalists working in the Caribbean, in conservation organizations or academic programs, may apply. Applicants should be students or early career ornithologists, conservationists, or wildlife professionals (i.e., not established faculty or senior staff of a conservation organization, less than 10 years post-graduation). A student must be enrolled in accredited Masters or PhD program in ecology, biology, conservation, or related field to be eligible. Applicants must be paid or sponsored members of BirdsCaribbean at the time of application.

Use of Funds: The funds can cover travel to field sites, living expenses in the field, or costs for equipment and supplies to conduct conservation projects. Examples of equipment and supplies include traps, cameras, automated recording units, nest boxes, etc. Ineligible costs include salary or other wages, overhead fees, etc. Projects that foster collaboration between scientists/naturalists in different island groups of the Caribbean, such as joint projects to test conservation techniques for similar species, will be favored. Application Guidelines:

Proposals may be submitted in English, French, or Spanish. All should have an English version of the abstract.
Applications should be emailed as a Microsoft Word document.
The application should include a cover page, proposal (download guidelines below), and a curriculum vitae for the applicant.
Separately, by email, three individuals who can attest to your effectiveness in previous work should submit letters of recommendation. For students, this would include your academic advisor.

Evaluation:

A committee appointed by BirdsCaribbean will review the proposals and award the grants.
The awardee will be required to submit a report one year from the day of the award explaining how the award money was spent and the results of the project to that point. The awardee is also asked to write an article for BirdsCaribbean’s blog about their work (informal article for a lay audience).
Awardees are encouraged to present the results of their work at the biennial International Conference of BirdsCaribbean and publish in The Journal of Caribbean Ornithology.

This fund will be for the conservation of any bird in the Caribbean as a reflection of Dave’s diverse interests. He was an important part of many projects, ranging from those of the Black-capped Petrel and Seabird Working Group to the scholarly debate leading to the elevation of the Bahama Yellow-throated Warbler to a full species. At the moment the fund contains $12,000. Our initial goal is to raise $25,000 so that we can award $1,000 every year to a worthy student or early career ornithologist, conservationist or wildlife professional. Not only will this fund encourage creative field work for projects that make a difference, but it will also help build the knowledge and skills of young conservationists that are urgently needed to make sure that the Caribbean birds and habitats that Dave treasured are still around for future generations to enjoy.

At the 2015 BirdsCaribbean meeting in Kingston, Jamaica, a round of beers was purchased in Dave’s honor, since he always seemed to have a cooler full when people wanted one (and even when they didn’t). Think of this fund like a cooler full of refreshing beverages that Dave would have around if he were here. We owe it to Dave to stock that cooler—to vitalize naturalists and empower them in their work to help wildlife. Please give a tax deductible donation to the David S. Lee Fund. Give generously. The more we put into the fund, the more we can give out each year. Thanks to all those that have contributed to the fund!

RESEARCH ARTICLES AND NOTES

Composition of bird community in Portachuelo Pass (Henri Pittier National Park, Venezuela)

Cristina Sainz-Borgo, Jhonathan Miranda, and Miguel Lentino

In Henri Pittier National Park, Venezuela, the low-lying Portachuelo Pass provides essential habitat for both resident and migratory bird species. Despite this, information about the composition of the bird community is scarce. In this study, Sainz-Borgo et al. survey and describe the species inhabiting Portachuelo Pass, highlighting key characteristics of the avifauna in this important ecosystem.

Mass fallout and stopover duration of Migratory Blackpoll Warblers (Setophaga striata) in Bermuda after Hurricane Nicole

Miguel A. Mejías and Albert J. Mejías

On 13 October, 2016, Hurricane Nicole made landfall over Bermuda. Mejias and Meijas acted quickly, utilizing the hurricane as an opportunity to document a species fallout event. Here, they present the results of their post-hurricane songbird surveys, documenting a significant fallout of Blackpoll Warblers and underscoring the importance of remote oceanic island refuges for fallout migrants.

Woodland size and vegetation effects on resident and non-resident woodland birds in Bermuda

Miguel A. Mejías and Erica Nol

While historically, Bermuda was home to lush, native, evergreen forests, human colonization in 1612 led to progressive habitat fragmentation and introduction of exotic trees. In this study, Mejías and Nol explore the impact of woodland size and vegetation features on species richness and bird abundance, specifically emphasizing the effects on White-eyed Vireos. Critically, they show that larger, less-fragmented woodlands are essential for supporting abundant and diverse bird communities.

Historical review of information on terns nesting in Bermuda, with prospects for re-establishing some of the lost species

David B. Wingate and Ian C.T. Nisbet

Early accounts from the Bermuda Islands suggest the presence of myriad nesting tern species on the islands; however, only the Common Tern survived into the 20th century. Here, Wingate and Nisbet review both the historic and recent records of terns on Bermuda, shedding light on the prospect of restoration and species recolonization using modern conservation techniques.

Abundance and distribution of Roseate Terns (Sterna dougallii) in the Virgin Islands

Louise M. Soanes, Judy Pierce, Daniel Nellis, Susan Zaluski, and Lewis G. Halsey

Due to a severe decline in the North Atlantic Roseate Tern populations in the 1900s, countries worldwide initiated conservation plans. However, few studies have focused on the Caribbean population of Roseate Terns. Using three decades of survey data, Soanes et al. detail the abundance and distribution of Roseate Terns in the Virgin Islands, identifying key breeding sites, reporting a gradual population decline, and calling for further conservation and research efforts.

Light-level geolocation reveals the migration route and non-breeding location of an Antillean Nighthawk (Chordeiles gundlachii)

Noah Perlut and Anthony Levesque

Though the Antillean Nighthawk is a relatively common species in the Caribbean, its migration routes and non-breeding location remain a mystery. In an effort to identify these locations, Perlut and Levesque attach a geolocator to a female Antillean Nighthawk, tracking and documenting her movements throughout a one-year period.

Novedades sobre la reproducción de dos especies de aves marinas poco comunes en Cuba*

Antonio García-Quintas, Laritza González Leiva, and Ariandy González González

The second breeding record of Audubon’s Shearwater (Puffinus lherminieri) and the fourth breeding record of Common Tern (Sterna hirundo), were detected in the Felipe de Sotavento and Barlovento cays of northern Ciego de Ávila, Cuba. These seabirds are uncommon in the country; so, new records of nests with eggs and chicks indicate the need for increased sampling in northern cays of the country. The studied cays are among the most important nesting sites for seabird colonies in Cuba in terms of number of species and breeding pairs.

*Erratum: Novedades sobre la reproducción de dos especies de aves marinas poco comunes en Cuba

An error was found in the García-Quintas et al. manuscript published earlier in this volume, in which the photographs of an egg and chick in Figure 2 represent Roseate Tern (Sterna dougallii), not Common Tern (S. hirundo).

Checklist of the birds of Finca Nolla, a recently protected area in northern Puerto Rico

Adrianne G. Tossas, Osvaldo Rullán, Robert J. Mayer, and Jean P. González

Throughout the 20th century, Finca Nolla, a wetland on the northwestern coast of Puerto Rico, was severely disturbed by agricultural and industrial practices. However, in 2011, the Puerto Rico Department of Natural and Environmental Resources purchased the land, designated it as a protected area, and began restoration activities. By thoroughly documenting the avifauna within Finca Nolla, Tossas et al. establish a baseline for future avian assessments and propose an upgrade of the conservation status to nature reserve.

A survey of Grenadians on seabird harvest in the Grenada Grenadines

Wayne A. Smart, Natalia Collier, and Virginie Rolland

Historically, overexploitation has contributed significantly to seabird population declines. Though protective laws have since been enacted, the extent of continued, illegal seabird harvest is unclear. Through their survey of the fishers and recreationists at the Fisheries Division office in Sauters, Grenada, Smart et al. shine a light on the persistence of seabird harvest in Grenada, highlight the sociodemographic factors that are associated with seabird harvest, and propose a possible community-based monitoring program.

Brown Boobies (Sula leucogaster) roosting at Washington-Slagbaai National Park, Bonaire, Caribbean Netherlands

Fernando Simal, Adriana Vallarino, Elsmarie Beukenboom, Rutsel Paula, Henry Beaumont, George Zaragoza, Esther Wolfs, Patrick Holian, and Elisabeth Albers

After anecdotal reports suggested that the seabirds roosting on the northwestern coast of Bonaire had been reduced to less than 60 individuals, Simal et al. began to investigate. From 2008–2010, they conducted roost counts at seven sites in Washington-Slagbaai National Park. Here, they document substantially higher seabird counts than previously suggested, with a maximum of 240 Brown Boobies in July 2009.

Lesser Black-backed Gulls (Larus fuscus) in Saint Vincent and the Grenadines and Grenada

Juliana Coffey, Natalia Collier, Vaughn Thomas, and Romould Compton

Though historically considered very rare in the West Indies, Lesser Black-backed Gulls have become fairly common non-breeding visitors to many Carribean islands, including most of the larger Lesser Antilles. Continuing this trend, here, Coffey et al. document the first records of Lesser Black-backed Gulls on both Saint Vincent and the Grenadines and Grenada.

The Pleistocene Burrowing Owl (Athene cunicularia) from The Bahamas

Ajay M. Patel and David W. Steadman

Despite the rarity of Burrowing Owls on Abaco, The Bahamas, today, many Pleistocene Burrowing Owl fossils have been recovered from the island. Using skeletal measurements, Patel and Steadman compare these fossils to modern specimens from western North America, South America, and Florida. Their results shed light on possible morphological adaptations of the Abaco owls to the island’s biogeography.

Nest site characteristics of the Critically Endangered Bahama Oriole (Icterus northropi)

Briana M. Yancy, Janine M. Antalffy, Michael G. Rowley, Cierra N. McKoy, Daniel C. Stonko, Lebron E. Rolle, Jennifer L. Christhilf, Scott B. Johnson, Shelley Cant-Woodside, and Kevin E. Omland

Building on the first documentation of Bahama Orioles nesting in pine forests on Abaco, The Bahamas, in this study, Yancy et al. further characterize these nest sites. By identifying specific habitat characteristics that are important for pine forest nests, this work not only enhances our understanding of Bahama Oriole nesting ecology, but also helps inform critical conservation efforts.

Using citizen-science data to identify declining or recently extinct populations of Bahamian birds

Ruby Bagwyn, Kylen Bao, Zuzana Burivalova, and David S. Wilcove

The widespread use of the citizen-science database eBird offers a unique opportunity to analyze trends in bird populations. Here, Bagwyn et al. use eight years of eBird sightings to identify Bahamian bird populations that have recently gone unrecorded. Through this, they find 43 populations, representing 25 species, that are potentially declining or extinct, suggesting areas that should be of key conservation concern.

Picky Palmchats (Dulus dominicus): do they really prefer to nest in royal palms?

Qwahn D. Kent, Maia Edwards, Tim Wu, and André A. Dhondt

While other communal-nesting species show clear nest tree preferences, little is known about whether Palmchats prefer to nest in certain palm species over others. To investigate this gap, Kent et al. characterized Palmchat nest trees in Punta Cana, Dominican Republic. Overall, Palmchats nested more frequently in royal palms and Hispaniolan silver thatch palms compared with cana and coconut palms and in taller, thicker trees, regardless of tree species.

Distinguishing between Roseate and Common Terns at breeding colonies in the West Indies

Ian C.T. Nisbet

The author sets out to bring attention to an ongoing misidentification problem between Roseate Terns (Sterna dougallii) and Common Terns (S. hirundo) on their breeding grounds in the West Indies and Bahamas. Observers should pay special attention to: adult bill color and breeding plumage, clutch size, and characteristics of nestling down feathers as well as leg color.

Black-capped Petrel Conservation Through Poverty Alleviation in a Haitian Community

Join Adam Brown as he takes us on a trip to Haiti, to the remote mountain village of Boukan Chat. This village and the people who live there are the focus of conservation efforts to save the elusive and endangered Black-capped Petrel. Find out more about village life and how sustainable agriculture has been helping both the people and the petrels.

The village of Boukan Chat, Haiti is a one-dirt road, dusty small village on the frontier of the Haitian border with the Dominican Republic. To get there from the capital city of Port au Prince is a 6-hour driving adventure that takes you from paved roads, to dirt roads, to riverbeds, and finally up a steep climb to the remote mountain outpost.

Life in the Village of Boukan Chat

With an average income of around $5/day, the residents of Boukan Chat all live in small and simple houses, constructed of concrete blocks with sheet metal roofing that is weighted down on the structure with assorted rocks. There is no power in the village, however, there is a single solar powered streetlight, which is a popular hangout for people after dark.

Everybody in the village is a farmer, from the moms and dads, to the grandparents, to the kids, to the babies on their parents’ (or siblings!) back. The food the people of Boukan Chat eat, is the food they grow. Farm plots range from backyard gardens at residents’ houses in the village to expansive multi-acre farms up in the hills behind town. The local farmers market is on Tuesdays, and as you can imagine, the whole village turns out for the weekly event.

There is no running water in or around the village. During the rainy season, residents capture and store water in cisterns, but in the dry season, they must travel up to 10 miles by foot, horse, or motorbike to collect their water from a community pump.

There are schools in the village, all of which are private. Often, what this means is that a single teacher in a one-classroom building teaches a mixed-age class of youth, ranging from kindergarten to high school. The classes meet for a couple hours each day, except in the summer – unless the weather is too severe, or a large farm harvest is taking place.

The village is represented in the regional men’s soccer league by an incredibly competitive group of local young men. Games on the weekend are highlights for the whole village and hundreds of people show up to the soccer field, one of the only flat spots in the whole village, to cheer the local squad on.

The Search for the Black-capped Petrel Begins

The Black-capped Petrel is an endangered seabird that nests in the Caribbean region. Its local name is Diablotín, which means ‘little devil’, a name likely arising from supernatural beliefs associated with the species’ habit of calling in the dark of night. Currently, the only known nesting colonies are on the island of Hispaniola, although recent evidence suggests that there might also be a small colony on the island of Dominica. With an estimated global population of between 1,000-2,000 nesting pairs, the species is endangered due to habitat loss, threats by introduced predators, and collision hazards along its flight pathways.

In 2011, the team from EPIC’s partner foundation, Grupo Jaragua, led by Ernst Rupp and consisting of an intrepid group of young field assistants, crossed the border from the Dominican Republic into Haiti and began searching for nesting endangered Black-capped Petrels on the slopes just above Boukan Chat. The team knew little of the village of Boukan Chat but were driven to search these hills, known as Morne Vincent, as they contained some of the last forested areas in Haiti and therefore were likely home to nesting petrels. That year, on that first mission to this area, the team discovered the first known active Black-capped Petrel nests ever recorded.

The Forests and the Farmers

The nesting colony on the forested slopes of Morne Vincent are immediately adjacent to the farming areas of Boukan Chat. These forests and slopes serve as a natural water catchment for the agricultural areas. While surveying on Morne Vincent, the petrel team made introductions with the farmers in the village. Realizing that preserving the forests of this area was crucial to conserving petrel habitat, the team from Grupo Jaragua, along with its partners from EPIC, JACSEH, SoulCraft, and Plant with Purpose endeavored to work alongside these farmers to conserve petrel habitat through sustainable agriculture, increased youth environmental education programming, and improved community savings programs that increase economic resiliency in the face of natural disasters (or a global pandemic!)

The evolution of our Black-capped Petrel conservation initiatives in Boukan Chat and the immediate impact they made on preserving local populations of the petrel, have made it the flagship program of the overall effort to preserve the petrel. With the idea of conserving the petrel through poverty alleviation, our initiatives penetrated most aspects of the Boukan Chat community.

Sustainable Agriculture in Action in Boukan Chat

As part of our sustainable agriculture program in Boukan Chat, we supported the creation of 22 Village Savings Farm Groups, made up of 2,600 people from 409 family farms. Within this program, we do classroom lessons that explain the theory behind sustainable agriculture. Specifically, farmers learned how improved human land use and crop management leads to higher yields, less soil erosion, and increased family incomes. In the field with the farmers, we have together created 520 compost piles, controlled 1,200 linear meters of gullies, installed 6,750 linear meters of anti-erosive barriers, and replaced 96 gallons of chemical pesticides with natural pesticides. Annually, the farm groups together save about $56,280. What do all these numbers mean for the Black-capped Petrel? Less stress on the human communities and reduced encroachment into the last remaining forested nesting habitat of the petrel.

As part of our youth environmental education program, we annually reach 3,600 students in Boukan Chat. Our programs focus on basic environmental themes such as soil and water conservation, the role of plants in the environment, and environmental stewardship in the community. With an eye towards the future, realizing that the youth of the community today will be the farmers of the community tomorrow, we are setting the foundation towards continued sustainable agricultural practices moving forward.

The Black-capped Petrel: A Village Icon

Along with the community, we celebrate the collaboration and commitment that we have made together to improve lives of both humans and petrels. We do this through sponsoring the local soccer team, who in turn wear a patch of the petrel on their soccer jerseys. We hire local artists to paint iconic images of the petrel on cisterns in the village. Annually, as part of the Black-capped Petrel Festival, we march together through the village, led by the Black-capped Petrel mascot and the local carnival band, and celebrate our successes together.

The conservation of the imperiled Black-capped Petrel is about the long game. While we measure our success in short term impacts, true lasting success and firm conservation of the Black-capped Petrel will take decades to implement. Its about buy in with human communities that live among nesting petrels and supporting the improvement of those human lives so that those humans, in turn, are able to make the choice to both support their families at the same time as preserving the petrel. While we have had great success since the first nest was found in 2011, we look forward to the challenges that lay ahead.

This project is funded in part by the Betty Petersen Conservation Fund (BirdsCaribbean), the US Fish and Wildlife Service, the American Bird Conservancy, and numerous individual donors.

ADAM BROWN is a Senior Biologist with Environmental Protection in the Caribbean (EPIC). Adam oversees EPIC’s Black-capped Petrel Conservation Program and has been an active member of the International Black-capped Petrel Conservation Group since 2011. Adam has pioneered the use of radar to track Black-capped Petrels to their nesting colonies on Hispaniola, has led expeditions to locate petrels on islands throughout the Caribbean, and is a strong advocate of collaboration among petrel conservation organizations within the Caribbean region.

Community Resilience Boosts Conservation of the Ridgway’s Hawk in the Age of COVID-19

For almost everyone 2020 has been a year of challenges and unexpected changes. The onset of COVID-19 has required all of us to adapt in unforeseen ways. For those working on the Ridgway’s Hawk Conservation Project in Dominican Republic, it has been a year full of surprises, compromises and hope. Find out from Marta Curti what has happened with Ridgway’s Hawk and efforts to promote its conservation in the DR since COVID hit.

Over the past ten years, The Peregrine Fund has invested heavily in recruiting, hiring and training a local team of dedicated, hard-working and passionate parabiologists – local community members who assist conservationists working in the field. We believe our conservation projects can only be successful when they have the support, cooperation and involvement of local people. We believe in this so strongly that a major goal is to build sustainability by eventually having it managed entirely by locals. In a normal year we rely a great deal on our in-country staff, but 2020 put them to the test. They took up the challenge. Even though neither our project manager, Thomas Hayes, nor I were able to travel to Dominican Republic during 2020, our teams on the ground kept working despite the pandemic. Remarkably, they have achieved most of the project objectives to date.

The Most Successful Breeding Year

In 2009, we began a Ridgway’s Hawk reintroduction program in Punta Cana. Prior to that, hawks had not been documented in the area for decades. Thanks to this program, we observed the first successful breeding attempt in 2013, when a young male hatched and fledged from a wild nest. Each year thereafter, the population has been growing steadily. We are very happy to report that 2020 has been the most successful nesting season in Punta Cana to date! During this breeding season, our team monitored 18 pairs of Ridgway’s Hawks, 17 of which made nesting attempts. A whopping 21 nestlings successfully fledged, and our crew was able to band 18 of them. Placing bands on young birds is a way for us to monitor the survival of the fledglings and their dispersal patterns.

Some Hitches and Delays

While our field work continued quite smoothly, we had to postpone a few important activities due to COVID-19. First, we postponed releasing any additional young hawks at our second reintroduction site (Aniana Vargas National Park) until 2021. Despite this setback, our team continued to monitor the hawks we had released there in 2019. While it did not observe any successful breeding attempts this season, a few bonded pairs and some nest building activity were reported!

Adapting to the Pandemic with Online Education

Our education and community outreach programs were negatively affected by the COVID-19 pandemic. We were unable to conduct face-to-face education outreach for most of 2020, and we had to postpone our pilot education campaign which had been scheduled for June.

This is disappointing after such great success in 2019 where, in October alone, we had reached 1,600 adults and children through our environmental outreach program. We were also unable to build on 2019’s outreach momentum. We had distributed 10 chicken coops, held 3 workshops (reaching 34 people, 19 of which were teachers) and visited 18 communities and 4 schools. However, islanders and conservationists are always willing and able to adapt to adverse situations. Although we could not engage in any live Ridgway’s Hawk Day activities this year, we hosted an online presentation followed by a question and answer session with members of our field teams in Los Limones and Punta Cana. We had 17 participants for this event.

An Exciting New Education Guide Goes Bilingual

We designed and printed new bilingual education materials (in Spanish and Haitian Creole). We provided some of these materials to our counterparts in Haiti for their community education activities. We continue to work on the text and design of our raptor-based environmental education guide, which we originally planned to distribute only in the Dominican Republic. The scope of the guide has now grown, and it will be made available to educators throughout the Caribbean, available in English, Haitian, and Creole Spanish.

Happily, last month, we were able to begin face-to-face educational programs on a limited basis. Partnering with the local platform ZOODOM, we worked with 12 children and 8 adults. They saw a live Red-tailed Hawk and Ashy-faced Owl and then received a short presentation on the Ridgway’s Hawk. Afterwards, the children colored a picture of the Ridgway’s Hawk.

The COVID Experience Has Taught Resilience

As we look to 2021, a great deal of uncertainty remains regarding travel and our ability to carry out face-to-face programs. Our main concern is the safety of our teams and the people in the communities where we work. However, what 2020 has taught us is that we are resilient and so is the Ridgway’s Hawk. Despite the pandemic, this year’s results and the efforts of our team truly give us hope that our project’s sustainability goals are achievable. The long-term protection of this Critically Endangered raptor is also making progress, before our very eyes. We want to thank the Betty Petersen Conservation Fund and all its supporters for making this work possible. Even in the midst of a global pandemic, please rest assured that we will carry on the work and the dream of community-based conservation.

First Encounters with the Elusive White-breasted Thrasher in Saint Lucia

The White-breasted Thrasher (Ramphocinclus brachyurus) is an Endangered songbird with an extremely small and increasingly fragmented range. Over 80% of the global population is found in Saint Lucia, most of it within the Mandelé range, which is considered the stronghold for the species at about 1,000 adults. (the remaining 20% is in Martinique). Bela Barata, Field Programme Officer with Durrell Wildlife Conservation Trust, takes us into the field to find and study this elusive bird.

On a sunny February morning, beneath the canopy of dry scrub forest along the central East Coast of Saint Lucia, staff of Durrell Wildlife Conservation Trust, Saint Lucia National Trust and the Division of Forestry prepared to complete the day’s task: checking camera traps in White-breasted Thrasher territory. One factor that limits reproductive success of this bird is nest predation by native predators such as the Saint Lucia boa constrictor and non-native predators such as rats, cats, and mongoose. The team had recently installed a network of camera traps, which take photos when trigged by motion, across the Mandelé range to get an indication of potential predator abundance in the area. These cameras were being monitored on a regular basis by Durrell and our partners.

Saphira Prepares to Meet the Thrasher

This assignment would turn out to be a great occasion for Saphira Hunt, Conservation Assistant at the Saint Lucia National Trust and Durrell’s Project Officer. Saphira has been working to raise people’s awareness to conserve this endangered bird for a number of years. Surprisingly, she has never seen a thrasher in the bush. On that day, however, while checking the cameras, she would come across the Endangered White-breasted Thrasher for the very first time in her life.

Saphira was thrilled with the opportunity and she vividly recalls her excitement: ‘We were trekking into Fer de Lance (Saint Lucia pit viper) territory with two tasks at hand. One was to check on the camera traps placed in the thrashers’ nesting sites and the second task was to see a White-breasted Thrasher live in its habitat—a first for me. Adorned with knee high snake gators, rubber boots, machetes, and snake hooks, we set off on the first trail ever, vigilant for any Fer de Lance along the way. The first camera trap was 5 meters ahead. Guided by a GPS unit, we walked single file; I strategically placed myself between two Forestry Officers each wielding a machete. I figured this positioning would decrease my chances of encountering the venomous Fer de Lance. As much as I was excited to see the White-breasted Thrasher in the wild, it would also be my first time seeing the Fer de Lance in the wild.’

The Sound of Silence (and the Thrasher’s Call)

As we trotted on, we kept our ears and eyes peeled, looking to the ground in hope of seeing the bird thrashing in the leaf litter or calling out to a mate. The lead Forest Officer spotted the first camera trap, while our team got ready to check the SD card for photos of potential predators. The area was scanned for any presence of Fer de Lance. We checked the first camera, and then another one. While we were on the move, a member of our team spotted the thrasher. Everyone stopped to admire, and then silence ruled: we heard nothing but the thrasher’s call.

Saphira describes her first sighting: ‘Onward, forward we went, checking two more camera traps along the trail. Suddenly, we heard the distinctive call of the White-breasted Thrasher. Pius Haynes (Senior Wildlife Conservation Officer of the Forestry Division) moved slowly forward, trying to spot the pair. There they were, perched on a low hanging branch. Everyone moved aside to allow me to quietly walk up to meet Pius where he pointed out the White-breasted Thrasher to me. Oh, what a sight! With their dark topcoats and blinding white under bellies, they were a stunning pair. I stood there in total silence letting the sounds of the forest fill my senses as I watched in awe.’

An Action Plan Took Shape in 2014

Saphira experienced a unique moment; the view of a rare and magnificent bird is something hard to forget. The White-breasted Thrasher was once more widespread in Saint Lucia, but the population is thought to be declining due to fragmentation of dry forest, the thrasher’s habitat, and increased depredation by non-native invasive species, such as rats, domestic cats, and mongoose. Our collaborator, Jennifer Mortensen from the University of Arkansas has been studying the ecology of the White-breasted Thrasher since 2006 and co-wrote the Species Action Plan (produced in 2014). Jennifer describes with great satisfaction how it feels to see a conservation plan being put forward for this species:

“I remember the day. It was 2014. A beautiful February afternoon. This was my 8th trip to Saint Lucia, but the ﬁrst time visiting during the “winter.” Clear skies, slight breeze, low humidity, few mosquitos. Why had I always come during the “summer” rainy season? Well, for one, the mangoes. But more importantly, I suppose, the rainy season is the breeding season for the White-breasted Thrasher. And I love that bird. They are kings of the dry forest. They are spunky. Some say they have an understated elegance that is unrivalled across the Caribbean. And they are Endangered, which is why we met that afternoon in Dennery in February of 2014 to hash out the species’ ﬁrst conservation plan. This plan, called the Gòj Blan Plan after the thrasher’s local Kwéyòl name, leads directly to the work we are doing now, six years later. To see those discussions and all that planning turning into conservation action is really exciting.”

Jennifer recently returned to Saint Lucia to support implementation of our White-breasted Thrasher project. She was a little nervous to return to Saint Lucia after six years away. She recalled, “While I’d kept in touch with friends and colleagues, and often thought about thrashers (still analysing ﬁeld data), I didn’t know what to expect. However, seeing the Pitons as we approached the island, the colourful roofs of Vieux Fort, the faces of friends at airport arrivals, and then ﬁnally, being back in the bush with the thrashers—it felt, at once, like no time and all the time had passed. Birds we banded in 2012, now 8 years older, were still thrashing about in the leaf litter only 60m from where we last encountered them.”

Betty Petersen Grant Supports Predator Study

We are working with a wide range of collaborators, partners, and funders to save and protect this endangered bird. With the support of BirdsCaribbean’s Betty Petersen Conservation Fund, our current work is looking into nest predation and investigating the abundance and activities of invasive predators like the mongoose. Predation is considered the primary cause of White-breasted Thrasher nest failure. It is also suspected to be the most important cause of juvenile mortality. Data we collect on non-native predator abundance and locations via our camera trap network will serve as a baseline and will assist us in the design of a non-native predator control programme, which is the next step of the project.

These activities are based on the Gòj Blan Species Action Plan and will help determine if directed non-native predator control is a viable management strategy to improve nesting success of the White-breasted Thrasher or whether efforts should be focused on other management strategies. We have a dedicated team comprised of wildlife oﬃcers, naturalists, and conservationists from the Saint Lucia Forestry Department, Saint Lucia National Trust, and Durrell Wildlife Conservation Trust. Together, and with BirdsCaribbean support, we are ready to promote the conservation of the White-breasted Thrasher in Saint Lucia. We look forward to reporting back after our next field season!

COVID-19 UPDATE

First case of Covid-19 in Saint Lucia was recorded in March 2020, followed by the government announcement of restricted rules to contain the spread of the virus: international flights were prohibited, a curfew was imposed, only essential shops remained opened, and schools were closed.

Our 2020 project goals of beginning the non-native predator control program and schools-based outreach activities could clearly not go on as planned. With schools closed, awareness activities will be postponed until the next academic year. Given the major disruption in international shipping, the equipment needed to implement the invasive species control program could not be delivered, causing us to shift this activity to next year as well. However, all was not put off… Ahead of us was the challenging task of completing another season of White-breasted Thrasher nest monitoring, initially proposed to start shortly after the predator control program in May 2020.

A Safe and Successful Nest Monitoring Season

Field activities were on-hold until July 2020, which is when the government granted permission to start reopening businesses and offices, following specific guidance and safety measures. Since outdoor activities such as fieldwork were considered safe, our team could proceed with nest monitoring. Bela Barata, Programme Officer for Durrell Wildlife Conservation Trust, said ‘of primary concern was the health and safety of our local staff, who are essential in delivering fieldwork and collecting all the data that underlie our efforts to save and protect the White-breasted Thrasher’.

In Saint Lucia, White-breasted Thrashers may breed between April and September, so we had to act quickly if we wanted to get a good sample of nests to monitor this year: ‘we had to adapt to the current scenario, make appropriate changes to deploy a reasonable survey effort and also ensure this could be done in the safest way possible’, said Bela. To safely deliver this activity, we reduced the field team to two people to ensure social distancing and used trail cameras to ‘watch’ nests. The cameras allowed us to reduce site visits to only once per week where we simply retrieved camera data, limiting contact between team members.

Camera traps were successfully installed in July 2020 and deployed for 1½ months. We recorded a total of 19 White-breasted Thrasher nests during this period, with nests occurring across each of our four field sites. Most importantly, by the end of the monitoring season, our team was well and healthy. We are now working to share the dataset, which contains thousands of photos. With this data our team will be able to calculate nest success, stages of nest failure, nest visitation by potential predators, and depredation events.

The success of this season survey under a global pandemic scenario was only made possible due to a well-coordinated response and the support of multiple partners. Saint Lucia National Trust and Durrell Project Officer, Saphira Hunt, was able to put together all equipment needed for field work in a noticeably short time. Saint Lucia Forestry Department staff was on stand-by, ready to install the cameras at any moment. Our White-Breasted Thrasher expert, Jennifer Mortensen from the University of Arkansas, worked quickly to provide a revised and updated monitoring protocol, setting a step-by-step guide that supported our field team without in-person supervision. From all lessons learnt, the delivery of the nest monitoring this year proved that we have a terrific in-country capacity, which is the bedrock of a relationship of trust and crucial for the long-term sustainability of this project. Together, we are working to achieve one shared goal: saving the White-breasted Thrasher from extinction.

Landbird Monitoring and Conservation in the Caribbean – We Need your Help!

Their entire population of Prairie Warblers spends the winter either in the Caribbean or Florida, making this a very important region for the species. During the winter Prairie Warblers like to live in coastal dry forests, mangroves, woodlands, orchards, and coffee farms; they may even show up in your garden!

BirdsCaribbean’s Bird Monitoring Group Working Group is developing an exciting new regional project to build capacity for more landbird monitoring in the Caribbean. It is essential to increase our knowledge about the status, trends, and habitat use of landbird populations as many species continue to decline. This includes our resident and endemic birds, as well as over 100 migratory species, many of them of conservation concern.

We plan to focus on developing a regional landbird monitoring program (modeled after our successful Caribbean Waterbird Census program). This will include training and resources to carry out:

Standardized Surveys – with different levels of monitoring available, depending on the questions and capacity of local partners,
Bird Banding – assisting partners ready for this step to establish banding stations to answer more detailed questions about movement patterns, habitat use and quality, abundance, survival, etc., and
Motus Tracking – expanding the network of Motus towers in the Caribbean to monitor migrant and resident birds. (the Motus Wildlife Tracking System is an exciting collaborative research network that uses coordinated automated radio telemetry arrays to study movements of small animals – learn more here)

Each of the three areas of monitoring have their strengths and weaknesses and are suited to answering different types of questions about our bird populations. To ensure that we are meeting the needs of local researchers, managers, and communities, we would like to gather information from those who are currently monitoring and/or banding landbirds in the Caribbean, that have done so in the past, or are interested in doing so in the future.

You can help us plan our work by letting us know who you are, what you do, where your activities take place, and how the Bird Monitoring Working group can help you. Just fill out our survey here:

English version: http://bit.ly/LandbirdSurveyEnglish
Spanish version: http://bit.ly/LandbirdSurveySpanish
French version: coming soon!

Your input will help us to design our project with everyone’s background, expertise, and research needs incorporated into the project.The success of this project will depend on the involvement of our many partners across the region, including wildlife professionals, scientists, educators, students, and volunteers/ citizen scientists.

Thank you in advance for your time and help!!!

Note: We recognize that most landbird work will likely be affected by the Covid-19 pandemic, and we understand that your activities this year will be very different from any other year: when filling out the survey, just let us know what you would have done in a ‘normal’ year. Most importantly, we hope that everyone is safe.

Why Landbirds?

Landbirds face many threats, including destruction and degradation of their habitats from human causes, such as inappropriate development, deforestation for agriculture, pollution, and invasive species. Severe hurricanes, droughts, and forest fires are also increasing, likely due to climate change. It is vital that we work together to monitor our landbird species so that we can identify the highest priority sites for conservation, restore habitats, and assess the impacts from threats and effectiveness of our conservation actions.

About the Bird Monitoring Working Group

The BirdsCaribbean Bird Monitoring Working Group is a committee that works to promote and support monitoring efforts throughout the Caribbean. The long-term vision of the group is to enable Caribbean stakeholders to build high-quality bird monitoring and training programs that have regional relevance and significance because of shared species and habitats. Within this context, the goals of the Working Group are to:

Foster inter-island cooperation and collaboration in the regional monitoring of shared species of birds (including neotropical migrants) and their associated habitats;
Work to significantly increase the number of skilled field biologists living in the region;
Build regional capacity to carry out standardized monitoring and training programs, including bird banding.

Joe Wunderle Comes Onboard as JCO’s New Editor-in-Chief

It is with great excitement that we are finally able to break some very big news — effective today, Dr. Joseph M. Wunderle, Jr. will be serving as the Journal of Caribbean Ornithology’s new Editor-in-Chief!

For most of us, Joe is symbolic of Caribbean ornithology. He has lived and breathed it almost his entire life. You would be hard pressed to find a Caribbean researcher out there that hasn’t cited one of Joe’s papers, had the pleasure of working alongside Joe, or most importantly, befriended Joe.

Dr. Joe Wunderle — We’re delighted that Dr. Joseph M. Wunderle, Jr. will be serving as the Journal of Caribbean Ornithology’s new Editor-in-Chief.

But what makes Joe an exceptional choice to lead the Journal of Caribbean Ornithology (JCO) into its fourth decade, goes far beyond his extensive research and academic background. From the beginning, Joe has demonstrated an unwavering commitment to the people of the Caribbean. He has taught and mentored numerous students, always sending them off into the world with a greater understanding and appreciation for the natural world around them.

In the world of peer-reviewed journals, we often talk about Impact Factors, which are a measure of how extensively a journal’s publications are cited, and thus a proxy for how important a journal is in its field. If we were to apply that same train of thought to the impact that Joe has had on the people, wildlife, and landscapes around the Caribbean, he would certainly be ranked highly.

And Joe is definitely no stranger to BirdsCaribbean (BC). He has been involved with the organization since its first year, 1988, earning him the Site Fidelity Award presented at last year’s Guadeloupe Conference. He has served as Vice-President of BirdsCaribbean from 1991–1995, and then took the reigns as President from 1995–1997. Joe has also been an active member of the Founders Award Committee (founded by Fred Schaffner) since it first launched at BC’s Grenada Conference in 2013. This committee awards the students who present the best papers in conservation research or management at the biennial conference.

Meanwhile, here at JCO, Joe’s name is a very familiar one. And while it’s true that some of our staff know Joe best in the following format — Wunderle, J.M., Jr., [Year]. [Article Title]. [Journal Name]. — we are all really looking forward to working more closely with the real Joe over the coming months. His leadership for JCO could not be a better fit.

Here are some great links for learning more about Joe:

Tracking Pirates of the Caribbean: An Interview with Dr. Rhiannon Austin

Magnificent Frigatebirds soaring like big black kites overhead are a familiar sight throughout the Caribbean. These birds are also commonly seen harassing and stealing food from other seabirds—a behaviour known as kleptoparasitism—earning them the reputation of being ‘Pirates of the Skies’!

These days, a careful watcher might also see a Magnificent Frigatebird fitted with a small tracking device. These birds are part of an ongoing project, ‘Regional-scale Conservation through Multi-territory Tracking of Frigatebirds,’ for which a workshop was held recently in Anguilla. Following the workshop, one of the attendees, Jennifer Wheeler, caught up with one of the project co-leads, Dr. Rhiannon Austin, in order to talk more about the history of the project and this unique seabird.

Jennifer, for BirdsCaribbean (BC): Hi Rhiannon. The workshop wrapped up just before COVID-19 shut down international travel. I’m glad you made it back to the UK—first off, how are you doing with coronavirus? I assume it has affected your work schedule?

Rhiannon: Thanks for asking! As in most places, it has changed things notably for us in the UK both professionally and personally, and we are all trying to adapt to the situation. I am currently employed as a Research Associate at the University of Liverpool, which has been shut since just after our workshop in mid-March, and we don’t know when it will reopen yet. Our fieldwork this season has been put on hold for now. However, we are doing our best to keep moving forwards and keep up communications. It is all about supporting each other.

BC: I believe we first crossed paths in mid-2016, when you were developing the proposal for the multi-island Frigatebird Project, but I think you had already started working in the region prior to that. What first brought you to the Caribbean?

Rhiannon: Yes, we corresponded in 2016, but met in person for the first time at BirdsCaribbean’s International Conference in Cuba, in July 2017, which was my first BC meeting. It was such a great experience and a fantastic opportunity to meet and hear from others working in the region. I first started working in the Caribbean in 2011, on a project with the Department of Environment (DoE) in the Cayman Islands that focused on Marine Protected Areas. Although my work on this project wasn’t related to seabirds, I became very interested in the seabird colonies on the islands, and always wanted to write a grant to go back and study them.

I did this after my PhD in 2015, and our grant was funded! At the time of the BC conference in 2017, I was managing our Darwin Plus project in the Cayman Islands, which started as a two-year collaboration between the DoE, Universities of Liverpool and Exeter, and the National Trust of the Cayman Islands. The project aimed to gain essential information on the at-sea movements, population status, and ecology of breeding seabirds in this UK Overseas Territory (UKOT). I was lucky enough to be able to continue working on the seabird populations here after this funding ended—last year was our fourth field season. The hope is that our collaborative group can continue studying these important populations over the long-term to gain a fuller understanding of inter-annual variability in behaviour and population responses to environmental change.

BC: So, your work with Cayman Islands frigatebirds led naturally to thinking about working across several islands?

Rhiannon: Exactly! The DoE and I started working together to tag and track frigatebirds in 2017. We collected some great data that really helped to improve our understanding of the at-sea movements and behaviour of this unique species during the breeding season. These data have also now been used to identify marine Important Bird and Biodiversity Areas (IBAs) during our Darwin Plus projects. We have discovered some interesting things about how Magnificent Frigatebirds from the Cayman Islands exploit their environment, including the tendency of birds to forage both coastally around reefs and sargassum drifts and within the open ocean. We have also detected sex-based differences in their foraging tactics, with males making more offshore trips than females when rearing chicks (you can check out our open access article in MEPS here).

Protecting this species is a real challenge as their large wingspans means that they have low energetic fight costs (i.e. they don’t have to use a lot of energy to beat their wings!), and therefore can forage over huge stretches of ocean. They don’t respect international boundaries and don’t need a passport(!), so it takes cooperative management from multiple nations to protect them across their entire range. The current project that I lead, along with Dr Jon Green at the University of Liverpool, really developed in response to these challenges. Our team wanted to do something to bring those working in the UKOTs together, to discuss ways to extend networks that will help to protect biodiversity. Frigatebirds are really a tool for helping to achieve this aim, as their unique traits make them a potential indicator species for marine biodiversity hotspots. They require better protection, as do multiple species and habitats within the Caribbean.

BC: Are all the Caribbean UKOTs involved in the current project?

Rhiannon: Yes, I am lucky enough to be working with partners in all 6 of the Caribbean UKOTs under the current project (Anguilla, British Virgin Islands (BVI), Cayman Islands, Turks and Caicos, Bermuda and Montserrat), as well as BirdsCaribbean who it is great to be partnering with. The recent workshop on Anguilla was attended by partners from all of these territories including the Anguilla National Trust (Anguilla), Department of Environment – Cayman Islands Government (Cayman Islands), Jost van Dykes Preservation Society (BVI), Department of Environment and Coastal Resources – Government of the Turks and Caicos Islands (Turks and Caicos), Department of Environment – Government of Montserrat (Montserrat), Department of Environment and Natural Resources – Government of Bermuda (Bermuda), and BirdsCaribbean (see photo). It was great to bring everyone together to discuss the work that we are doing, and how it might help with the large task of addressing conservation issues within marine and coastal environments in the UKOTs.

I’m currently combining and analysing data from multiple Caribbean frigatebird populations to investigate what habitats this species uses at sea and on land (where they like to roost and feed), and to predict suitable habitat across the region (including within areas that we have no data for). The hope is to use frigatebird tracking data in habitat modeling approaches to identify areas of ecological importance relevant to not only frigatebirds but other mobile marine vertebrates. There is another year and a half left on this project and it will end with a large workshop that our project team plans to host during the next BirdsCaribbean Conference in 2021. We hope to open this up to those working in non-UK states and territories in the Caribbean that are interested in seabirds and related conservation issues.

BC: Have you found partners outside of the UKOTs?

Rhiannon: Yes, I’ve recently started a collaborative project with NGOs and Government departments in the Yucatan Peninsula in Mexico. They have large and important populations of seabirds in this area but desperately lack funds for monitoring and conservation. We were due to start preliminary work on this project during the spring/summer, but this had to be delayed for now because of recent events. However, we are committed to seeing this happen once borders open up again and it is safe to proceed. Through the Frigatebird Project, we have also recently started collaborating with some fantastic conservation and research organisations in the States (the Avian Research and Conservation Institute – ARCI) and Canada (University of New Brunswick / NSERC), who have worked on frigatebird populations in the Florida Keys and Barbuda, respectively. I am also always keen to make new connections with those interested in the spatial ecology and conservation of seabirds and other marine vertebrates in the region.

BC: Where are you finding funds for this work?

Rhiannon: This work is largely funded by the UK Government’s Darwin Plus grant scheme, which aims to fund local projects to help protect biodiversity and the natural environment in the UKOTs. The team and I at the University of Liverpool have been lucky enough to have undertaken a number of projects in the UKOTs supported by Darwin Plus, and I really hope that our collaborative group will continue to have success working under this scheme, as our conservation and research activities continue in the Caribbean. My work in Mexico is currently funded by an ‘Early Career Researcher’ grant provided by the University of Liverpool, but we hope to seek funds for longer-term work in the future.

BC: Where would you like to see the project go in the future?

Rhiannon: We really hope that this project, and the outputs that it provides, will help to build new collaborations and working relationships amongst those in the UKOTs (and more widely) that have shared issues and/or knowledge that can be exchanged. The ultimate long-term goal is that this will lead to the development of transboundary management strategies. This a huge task and not an easy one that can be addressed in this project, as it requires involvement of so many nations and organisations. Here, we are starting by identifying training, data and management needs in the 6 UKOTS, and will then undertake supporting activities in these territories (for example, colony surveys or feasibility studies) that will hopefully lead to future funding and longer-term project work. Our final workshop in 2021 will focus on ‘Connectivity and Networks’, and it will be a great opportunity to make steps towards these objectives.

BC: Frigatebirds connect the Caribbean – and beyond. What else makes frigatebirds special?

Rhiannon: Frigatebirds are unique. If I could spend the rest of my lifetime studying them, I would be happy! They are very different from many other seabirds, both in terms of their at-sea behaviour and breeding strategies. Associated with this, they have evolved some intriguing morphological (body) characteristics. For example, they lack waterproofing on their feathers so are constrained to forage at the ocean’s surface. Because they don’t dive under the water, they also lack webbing on their feet, which are adapted for roosting in mangrove trees where they nest. Frigatebirds also have impressive wingspans which allow them to roam huge distances with ease, even when rearing chicks! They also have a very interesting breeding strategy. Females have much greater roles in parental care than males: while the male deserts the chick after only a few months, females may continue rearing chicks for over a year.

Frigatebirds get a lot of bad press because they regularly steal food from other birds. Did you know that the name ‘frigatebird’ and associated nickname ‘Man O’War bird’ refers to the warships favoured and feared by pirates between the 16^th and 19^th centuries? Personally, I think that this foraging tactic is fascinating and actually quite smart in an environment where prey distributions may not be predictable in time or space! Despite my obvious biases towards frigatebirds, we have a diversity of seabirds in the Caribbean (>20 species) that use a range of life history strategies to successfully exploit and breed in this environment. There is so much to learn. In addition to frigatebirds, I spend time working on boobies, gannets, and shearwaters, but the former remain my favourites!

BC: You have worked in other parts of the world, including the Mediterranean… how would you compare the two regions?

Rhiannon: I have always gravitated towards warmer climates, and I feel a strong affinity with the Caribbean. It is where I hope to be based in the long-term. I worked in the Mediterranean on shearwaters for 4 years, and the two regions do have some similarities. Both have high levels of biological connectivity between the many coastal habitats that they contain, and both experience high levels of human activity and associated pressures on their marine and coastal ecosystems.

As with the Caribbean, the Mediterranean has many conservation issues to overcome. However, there are a number of initiatives in the Mediterranean that we might be able to learn from to help with the particular challenges faced in the Caribbean. For example, recent efforts to undertake observer programmes onboard fishing vessels are helping to address bycatch of seabirds. Similarly, there are initiatives to identify and designate interconnected networks of MPAs. Spain’s efforts at site protection are a good example of this. Nevertheless, these types of conservation action only work if multiple stakeholders and nations work together in their efforts, which we all know is challenging. One of the reasons that I enjoy working in the Caribbean so much is its people, and the diversity of birds in the region, many of which we still know so little about. There is so much here to discover and protect!

BC: Do you have a favourite memory from the project that you would like to share?

Rhiannon: There are so many to choose from! Some funny and some just magical! I’ll give you one of both. I think one of my favourite ‘amusing’ memories was watching one of my research assistants (who hates fish) being regurgitated on by a frigatebird while in a very precarious position during work at the colony, which he could not move out of for about 10 minutes. He had to grin and bear being covered in half-digested fish while the rest of us tried desperately not to laugh as we worked!

Withholding regurgitates, the Booby Pond Nature Reserve on Little Cayman is one of my favourite places on earth! Working there over such extended periods of the year means that I am lucky enough to get to see sights and behaviour that few in this world observe. These include adults feeding their chicks, scuffles between nest neighbours, juveniles playing with nesting material in the sky, and fledglings finding their wings and taking off the first time! It is a privilege and an honour to work with such amazing creatures. The noise of the colony alone is something to behold! Imagining these sights and sounds is definitely a great way to find peace and calm while in lockdown in the UK (check them out in this video clip!).

Birds of the World – Free to BirdsCaribbean Members

BirdsCaribbean is excited to announce a new collaboration with the Cornell Lab of Ornithology that gives our members FREE access to Birds of the World – the best website for comprehensive information on all of the world’s species of birds.

Birds of the World is a powerful new online resource that brings together scholarly content from four celebrated works of ornithology into one rich and colorful hub where you can find comprehensive, authoritative information on birds. All of the information from Birds of North America and Neotropical Birds (originally published by the Cornell Lab) has been merged with information from Handbook of the Birds of the World Alive and Bird Families of the World (originally published by Lynx Edicions) into one online platform.

With the integration of millions of bird observations from eBird and images from the Macaulay Library, Birds of the World is the most powerful ornithological resource ever created. It’s a single platform where biologists, birders, and anyone with an interest in birds can explore comprehensive life history information on birds.

Every Bird has a Story

The platform includes 249 bird family accounts, and species accounts for all 10,721 known species. Content includes topics such as description, taxonomy, distribution, habitat, diet, behavior, breeding, movement, and more. All species accounts have range maps and a growing number have “intelligent maps”—science-based abundance maps and animated migration maps (created from eBird data). Magnificent colour plates from many of the world’s top illustrators are backed up by the massive Macaulay Library resource – a media asset of photographs, video and audio recording. Every species displays its IUCN conservation status and additional ornithological notes as appropriate. The common species names are even available in more than 50 languages!

And here’s a neat feature – because it is linked to eBird, when you are logged into Birds of the World each species account shows a blue badge indicating whether or not you’ve seen, photographed, or taken audio recordings of the bird. If you’re not yet an eBird user, now is a perfect time to sign up and start using this wonderful app to find birds, keep track of the birds, and contribute to science! And if you’re in the Caribbean be sure to use our special eBird Caribbean portal.

The Birds of the World home page has a few species accounts that are available for a free preview, allowing you to check out all the great info available on this site.

One overriding feature of the resource is that it will be constantly revised by ornithologists to include the latest taxonomic revisions and latest information about each species.

Working with Seabirds in the Caribbean? We Want to Hear from You!

Magnificent Frigatebirds at a nesting colony. (photo by Rhiannon Austin)

Do you study seabirds as a student, scientist, or independent researcher? Do you manage nesting islands or work in a seabird colony? Do you teach environmental education about seabirds or lead birdwatching groups? Are you a project director, a volunteer, a retiree active in seabird conservation? If so, we want to hear from you!

You can help BirdsCaribbean’s Seabirds Working Group (SWG) by letting us know who you are, what you do, where your activities take place, and/or how the SWG can help you. Just fill out our survey here! (Spanish and French versions are available below.)

Note: We recognize that most seabird work will likely be affected by the Covid-19 pandemic, and we understand that your activities this year will be very different from any other year: when filling out the survey, just let us know what you would have done in a ‘normal’ year. Most importantly, we hope that everyone is safe.

Why seabirds?

Seabirds are among the most threatened groups of birds globally. The twenty-three species of seabirds that breed in the Caribbean and Bermuda are all under threat, with some having experienced dramatic declines in recent years. Many of these species have meta-populations, thus understanding their regional population trends and ecology is especially important. To conserve Caribbean seabirds efficiently, we must work together on multiple fronts to understand, promote, manage and protect this important group.

Save Our Seabirds Poster, produced by BirdsCaribbean. This poster is available in English and Spanish – let us know if you need copies for outreach and education on seabirds!

Why a Seabirds Working Group?

Since 1999, the BirdsCaribbean Seabirds Working Group (SWG) has been working to bring people who are studying and/or conserving seabirds together to promote seabird research and conservation. Its purpose is to:

Bring together those working on, and interested in, seabirds within the Caribbean
Provide a forum within which to share information amongst the community on (past, present and future) research, monitoring, and management activities in the Caribbean relevant to seabird conservation
Seek new avenues to extend seabird conservation activities within the Caribbean and support those already working towards achieving this goal!

During the last 20 years, we have seen a great increase in appreciation for the plight of Caribbean seabirds, and launched several research and conservation efforts. However, much remains to be done. Now more than ever, we need to keep working together for seabirds.

What’s happening with the Seabirds WG?

After many years as co-chair of the group, Will Mackin took a step back and, in 2020, Yvan Satgé and Rhiannon Austin joined Ann Sutton as co-chairs of the group. Their interest and enthusiasm promise to revitalize the group.

How can the Seabirds WG serve you better?

In order to strengthen our joint seabird efforts, we must first bring the group more closely together. Therefore, we are reaching out to seabird professionals who are working in the Caribbean, to find out who you are, where you work, and how the SWG can help. Please fill in our online questionnaire. This will help us to help you in your work. Also, please feel free to share the questionnaire with your colleagues and encourage them to fill it out.

Here are the links to the online questionnaires

Working together we can do more to save our seabirds!

We look forward to hearing from you,

Ann Haynes-Sutton, Rhiannon Austin and Yvan Satgé (Co-chairs, BirdsCaribbean Seabirds Working Group).

From the Nest – Day 5

Celebrate the Caribbean Endemic Bird Festival (CEBF) with us in our virtual “From the Nest” edition! Have fun learning about a new endemic bird every day. We have colouring pages, puzzles, activities, and more. Download for free and enjoy nature with your family at home.

Endemic Bird of the Day: Ridgway’s Hawk

The Ridgway’s Hawk is found only on the island of Hispaniola, which is shared by the nations of Haiti and Dominican Republic. It is one of the most Critically Endangered raptors in the world, with fewer than 500 birds remaining. It hunts by maneuvering through the thick forest with the help of its broad wings and long tail, or by perching low to the ground in open areas scanning for prey. It feeds on snakes, as well as lizards and skinks, frogs and toads, small rodents, bats, and birds.

This hawk often builds its nest right on top of an active nest of the Palmchat, the national bird of the Dominican Republic. The hawks add larger twigs on top of the existing Palmchat nest, without causing any harm to the smaller birds nesting below. It’s like a two-story building for birds! The Ridgway’s Hawk is not shy around people and will even nest close to settlements and roads. However, nesting pairs are quick to defend their territory against humans or any other predator—they will vocalize loudly and chase off the intruders.

Since the late 19th century, the Ridgway’s Hawk population has been in steep decline. Much of their native habitat is disappearing through clear-cutting of forests and wildfires. Birds are also shot or chicks taken from the nest and killed as people fear these beautiful hawks will prey on their chickens. Fortunately conservationists at The Peregrine Fund, working in partnership with local communities, are making great progress in saving this species from extinction. BirdsCaribbean is supporting on-the-ground conservation work for this species through its Betty Petersen Conservation Fund. Learn more about this species, including its range, photos, and calls here.

BIRDSCARIBBEAN’S GLOBAL BIG DAY — JOIN US!

BirdsCaribbean is excited to be hosting a fundraiser that focuses on the energy, excitement, and comradery that’s associated with Global Big Day!

Global Big Day is an annual event in which birders, often in teams, travel around an area trying to observe as many bird species as they can in a 24-hr period of time. Global Big Day is happening on May 9th this year!

Because of safety concerns with COVID-19, Global Big Day will have a different feel to it this year. Many of us will be birding individually, and from a safe place*.

In an effort to keep the event exciting, and give us all an opportunity to celebrate safe birding, BirdsCaribbean has created a fundraiser that brings us all “together” on virtual teams that can engage in friendly competition to (1) raise the most funds, and (2) collectively see the most species of birds on Global Big Day.

GET INVOLVED BY

Creating or joining a birding and fundraising team by clicking the JOIN button on the campaign page.

Once on a team, help personalize your team page with fun photos and your own lingo, and then invite family, friends, colleagues, or members of your birding community to join your team and/or donate to your team.

By inviting people to your team, you are (1) raising awareness for BirdsCaribbean and the Journal of Caribbean Ornithology, (2) encouraging more fundraising to keep the Journal going, and (3) promoting Global Big Day and the importance of conserving birds and their habitats.

and/or . . .

Simply making a donation to one of the birding and fundraising teams.

By doing so, you will have (1) helped support the Journal, and (2) encouraged that team to bird as hard as they can on Global Big Day.

and/or . . .

Committing to spending some time (or the entire day!) birding on Global Big Day (May 9), being sure to keep track of what you see and then entering that information into eBird. We hope everyone will do this, whether or not they join a team or fundraise.

This will be a fun event to fundraise for and get excited about! Be ready to set yourself up in a safe place* and go birdwatching for as much of the day as possible, knowing that all of your teammates, friends, and BirdsCaribbean community members are doing the same!

Everyone should plan to submit their observations to eBird (or eBird Caribbean). Then we’ll tally them up and see how we all did! We will send out more information about this as the event draws closer.

WHY THIS IS IMPORTANT

We are living in unprecedented times. The important role that science is playing in understanding COVID-19 and finding solutions is more clear than ever. What science does to inform and improve public health, it also does for conservation of wildlife and nature.

BirdsCaribbean’s mission is to conserve birds and habitats throughout the Caribbean islands. This depends in large part on science—investigating causes of species decline that can then inform management and conservation actions.

To share that science, our community of researchers depends on the Journal of Caribbean Ornithology (JCO). This in-house, peer-reviewed publication has served our community for 32 years and counting. But the JCO needs help to keep its publications free and open-access to the world. Explore the JCO here.

HOW YOUR GIFT WILL BE USED

This fundraiser will benefit the Journal of Caribbean Ornithology.

We are proud of our Journal and want to keep it free and open access to everyone. To do this, we need help fundraising to cover the Journal’s modest operating costs.

JCO has recently experienced remarkable growth, including adding many new and talented staff members, creating a highly efficient workflow, building a new website, completing fully-accessible Archives dating back to Volume 1, Issue 1 in 1988, and so much more.

JCO is an invaluable resource to thousands of Caribbean students, researchers, and conservationists, providing an unparalleled body of ornithological knowledge for the Caribbean region through its free, fully searchable website. This is why we are asking for your help in fundraising for JCO.

No matter what, we hope everyone will participate. You can bird by yourself, create a team or join a team, and then fundraise! Or you can simply make a donation, investing in science to help Caribbean birds. No gift is too large or too small.

As with everything in the Caribbean we will be successful when our whole community pitches in, so let’s do this together. We know we can count on you to help!

ABOUT GLOBAL BIG DAY

Global Big Day is organized by the Cornell Lab of Ornithology. Last year, people in more than 175 countries participated, setting a record for the most birds seen in one day all over the globe. Learn more here about this important citizen scientist initiative.

PRIZES WILL BE AWARDED TO:

(1) the team that raises the most funds

(2) the team with the most creative name and stylish fundraising page

(3) the team that sees the most bird species on Global Big Day

(4) the team that sees the most endemic species on Global Big Day

(5) the team with the best “find” of the day (unusual, rare, plumage aberration, etc.)

(6) the team with the best bird photo of the day (must be posted on eBird along with your list)

There will also be “Hidden Prizes”; the categories for these will be announced just prior to Global Big Day AND throughout the day on Global Big Day.

SAFETY

*Given the safety concerns the COVID-19 virus presents for doing Global Big Day counts, we recommend that you bird in your backyard. If it is safe to go out on May 9th be sure to choose birding locations that (1) comply with your municipality’s COVID-19 safety guidelines (i.e. social distancing and travel guidelines), and (2) comply with your personal safety preferences. And so whether you we will be birding at a local park, within your own backyards, or from your bedroom windows, we will all be enjoying the opportunity to distract ourselves with some safe, fun birdwatching. Additionally, we will all be birdwatching “together” for a great cause that unites us!

Thanks in advance for participating and supporting our fundraiser, however you can! We hope to see lots of teams forming throughout the Caribbean, US, Canada and beyond! We will keep you updated with more news and details about our Global Big Day, such as how to keep a count of your birds and enter your data on line – stay tuned!

It Takes a Village: The Importance of Community Engagement in Conservation

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 gives us an update on the exciting work of The Peregrine Fund to save this Critically Endangered raptor.

Since 2000, when we began our project to conserve the Critically Endangered Ridgway’s Hawk in the Dominican Republic (DR), we began to hire and train local crew members to help carry out the field work. In 2011, we increased our recruitment and training efforts greatly. One of our main goals is to make the project sustainable in the long-term, which means giving locals the opportunity and the means to support their families while working directly for conservation.

We currently have over 20 Dominicans employed on our project. Most were born and raised in the very communities where we work, right in the heart of Ridgway’s Hawk territory. These residents range in age from late teens to over 60. They are trained in nest searching, monitoring, data collection, data entry, tree climbing, banding, treating nests to prevent nest fly infestations, and environmental education techniques. They spend long hours in the field, hiking over rough terrain, sometimes in oppressive heat and humidity or torrential downpours, to monitor and protect the hawks. While we are always so grateful for the work they do, this year, more than ever, their commitment to this project has proved invaluable.

Communities Take Up the Reins During COVID-19

Due to the COVID-19 outbreak, Thomas Hayes (Ridgway’s Hawk Project Director) and Marta Curti (Ridgway’s Hawk Project Environmental Education Specialist), will not be able to travel to the DR for the next several months, if not longer. If this were a “normal” year, we would both be planning a trip now, as the next few months are critical to our project’s success. Ridgway’s Hawk breeding season is in full swing and it is important to continue monitoring, banding, and treating nests. Thanks to our local crew, this work is being accomplished without a hitch!

At our first reintroduction site, the Punta Cana Resort and Club, our team is monitoring 17 pairs. Six of these pairs have hatched 13 young so far this year, while 9 have eggs waiting to hatch! This is an incredible achievement, considering that Ridgway’s Hawks hadn’t been documented in this area since the 1970s and breeding pairs didn’t start to form there until 2013! Though our environmental education efforts have been postponed in order to maintain social distancing, we were still able to reach 1,594 individuals at the beginning of the year. Our crew in Los Limones had a beautiful mural painted at the entrance to the town.

Los Brazos: An Eco-Friendly Release Site for Ridgway’s Hawks

While our seasoned crews are doing an amazing job in Punta Cana and Los Haitises National Park, we are particularly grateful for the newest additions to our team – our crew from the town of Los Brazos, located within the Aniana Vargas National Park in Dominican Republic. The small town of approximately 100 people relies heavily on the production of shade-grown certified organic cacao. Young and old, men and women, work daily to harvest, dry, process, and sell the crop.

The town itself consists of one dirt road with houses scattered on either side. In and around the town are cacao plantations interspersed with tall trees, wildflowers and wildlife. To maintain the organic certification, they must heed certain rules: no use of pesticides, no killing of wildlife, no cutting of forests. This, and the fact that this area was designated as Aniana Vargas National Park in 2009, was the main reason we chose this area as the newest site for Ridgway’s Hawk releases. Though every area has its unique challenges when it comes to releasing birds of prey, we knew we would be ahead by leaps and bounds releasing birds here. Thanks to support from the Betty Petersen Conservation Fund, we were able to release 25 young hawks in this area in 2019.

Exciting News to Report

Though we had planned to release another group of hawks this coming field season, we have decided to postpone this year’s releases due to the COVID-19 pandemic. However, thanks to our local crew, we have some amazing news to report. Our team has documented a pair of hawks building a nest in the area. This is the first pair formed from the previous year’s cohort of released birds, and a huge step in developing an additional hawk population in this region.

While there is so much uncertainty in the world at this time, it is an opportunity to focus on the things we are grateful for. I, for one, deeply appreciate the work of our amazing team and their unending dedication to protect this hawk. And I am grateful to the Betty Petersen Conservation Fund and BirdsCaribbean for continuing to support our work.

By Marta Curti, The Peregrine Fund. Marta began working as a field biologist with The Peregrine Fund (TPF) in 2000 when she worked as a hack site attendant on the Aplomado Falcon project in southern Texas. She has since worked as a biologist and environmental educator on several TPF projects from California Condors in Arizona to Harpy Eagles and Orange-breasted Falcons in Belize and Panama. She has been working with the Ridgway’s Hawk Project since 2011. This project is funded in part by BirdsCaribbean’s Betty Petersen Conservation Fund. Please donate to help this save the Ridgeway’s Hawk!

Protecting the Snowy Plovers of Coche Island Through Science and Community

Josmar Marquez, from AveZona, has lead bird monitoring projects on Coche Island in Venezuela since 2018. In addition to data collection, his work involves mentoring young conservationists and promoting nature-friendly behavior changes in the local community of the island. Here, Josmar describes his most recent Snowy Plover monitoring season and some exciting firsts for shorebird monitoring in Venezuela. (More photo and Español debajo)

In Venezuela, thanks to the support of the BirdsCaribbean David S. Lee Fund, AveZona and the ARA MACAO Scientific Foundation have carried out population surveys of Snowy Plovers (Charadrius nivosus tenuirostris) on Coche Island. A large number of the birds have been recorded in the “Salina de San Pedro de Coche.” This has lead to an appreciation and increased value of the island as this species is threatened in the Caribbean region.

Our project formally began in 2019, and since then we have conducted monitoring visits monthly to the San Pedro de Coche salt pans. Before we stepped foot in the field, the first step was to receive permission from the Ministry of Ecosocialism (MINEC) for the relevant permits to be able to move forward with the project. Thankfully, we were successful.

During our monitoring visits, we record the following information: number and location of Snowy Plovers, their age (adults or juvenile), sex, and any reproductive activity. In addition to monitoring, we also have indivudally marked some of the birds. Our team marked the first Snowy Plover in Venezuela in September 2019. It may seem like a small feat but it represents a lot of work! The birds are marked with black flags and white codes (right leg) and metal rings (left leg). Marking the plovers will help us better understand the behavior of each individual and to determine their site fidelity. In addition, we can learn if there is any migratory movement across the Caribbean for our local population of Snowy Plovers. To date, we have tagged seven individuals.

In February and March, 2019, we were fortunate to count Snowy Plover nests and chicks in the San Pedro salina. Joining us for this activity were students from the local community at Napoleón Narváez Bolivarian High School. It was rewarding to share information about these precious birds with young people and they were amazed to learn that the salina is so important to the Snowy Plover and other bird species (for example, Least Terns also nest there).

How many plovers are there?

Currently, we are partnering with with Adrián Naveda-Rodríguez from the Department of Wildlife, Fisheries and Aquaculture at Mississippi State University, United States. Together, we are working on the detectability and abundance of the Snowy Plover in eastern Venezuela. The preliminary analyses are using samples from the non-reproductive season, from counts made at 12 points in the San Pedro de Coche salina.

We modeled the relationship between detection probability and air temperature, time of the day, and distance to salt. We included covariates for the number of feral dogs, horses and salt miners when modeling abundance. Detection probability was negatively affected by the distance to salt piles (0.49, 95% CI=0.49-0.5). Abundance was not associated with the presence or abundance of domestic animals nor salt mining activities. We estimated there were 96 (95% CI: 46-201) and 116 (95% CI=61-220) Snowy Plovers in February and December, respectively. We hope to present this information in more detail at the next NAOC and subsequently we plan to publish our results in a scientific journal.

Our group participated in the 22nd International BirdsCaribbean Conference in Guadeloupe in July 2019 and in the Western Hemisphere Shorebird Group Meeting in October 2019 in Panama. We were so excited to present the latest results from our research and the ways in which we involve the community in our projects.

A community effort

Our partnership with the community has continued beyond school field trips. Recently, we created a unique bird-inspired mural in the school of “La Uva” community which, of course, included depictions of the Snowy Plover and the Least Tern. It is truly a beautiful work!

One of the reasons for working in this region is to promote the integration of communities that have historically been marginalized from science and conservation. In search of improving this situation, we are carrying out activities within this project that integrate and dignify the local community, and also give recognition to the worldview of the inhabitants of the biological diversity of their island.

Since the beginning of this project, we understood that in order to protect the salina and other places on the island, it is necessary to work hand in hand with the locals. We are very grateful for the school district of Coche Island, which has allowed us to work with educational institutions. Also, we are especially fond of the Napoleon Narváez Lyceum High School 9th Grade class, and teachers from various educational institutions for their receptivity and commitment. There are many locals that have opened their doors and hearts to this project and our team: Antonio Ros, Daniel Serva, Oscar Riera, Jose Gonzalez, Jesus Escalona, JC Fernández Ordoñez.

Many obstacles can arise when executing a project of this magnitude in Venezuela, but thanks to the constant support of BirdsCaribbean (including the David S. Lee Fund for Conservation) we are achieving our objectives. It’s very important to carry out this project that will help us to better understand the population of the Snowy Plover in the islands of the Venezuelan Caribbean. For me, it is a beautiful, very peculiar bird with very interesting habits. Luckily, in Venezuela it still can be observed very frequently in some places. Being able to say that there is a reproductive colony on Coche Island, and that it remains to this day, is a light of hope in the face of the global ecological crisis.

Please enjoy these short videos showing our work with the community from our Ave Zona Facebook page!

Josmar marquez, de AveZona, ha liderado proyectos de monitoreo de aves en Isla Coche, Venezuela, desde el 2018. Además de la colecta de datos, Su trabajo consiste en asesorar a jóvenes conservacionistas y la promoción de cambios conductuales ambientalmente amigables en la comunidad local de la isla. Aquí, Josmar describe su más reciente temporada de monitoreo del Chorlito Nevado.

En Venezuela gracias al apoyo de la beca David Lee, de BirdsCaribean, AveZona y la Fundación Científica ARA MACAO realizan el proyecto de evaluación poblacional del Chorlito Nevado (Charadrius nivosus tenuirostris) en la isla de Coche. En “Salina de San Pedro de Coche” se ha registrado un alto número de aves, lo que ha llevado a un aumento en la apreciación del valor de la isla para la especie, que se encuentra amenazada en la región del Caribe.

El proyecto comenzó formalmente en 2019, y se están realizado salidas mensuales a la salina de San Pedro de Coche. Antes de dirigirnos al área, el primer paso fue recibir el permiso del Ministerio de Ecosocialismo (MINEC) para el estudio de campo. Afortunadamente, tuvimos éxito.

Durante las visitas de monitoreo, anotamos la siguiente información: cantidad de individuos y localidad, edad (adultos o juveniles), sexo, y actividad reproductiva del Chorlito Nevado. Además del monitoreo, también hemos marcado algunos individuos. Nuestro equipo marcó el primer Chorlito Nevado de Venezuela en septiembre de 2019. ¡Toda una hazaña! Se usaron banderas negras con códigos blancos (pata derecha) y anillos metálicos (pata izquierda). Marcar los individuos nos ayudará a entender mejor su comportamiento y determinar su fidelidad al sitio. Además, podríamos llegar a saber si existe algún movimiento migratorio entre esta población y el resto del Caribe. Hasta la fecha se han logrado marcar 7 ejemplares de Chorlito Nevado.

Durante los meses de Febrero y Marzo de 2019 logramos contar nidos y pichones de Failecito en la Salina de San Pedro. A esta actividad asistieron jóvenes del Liceo Bolivariano Napoleón Narváez. Fue muy gratificante compartir información sobre estas preciosas aves con los jóvenes y se sorprendieron al saber que la salina es tan importante para el Chorlito Nevado y otras especies de aves (por ejemplo, el Charrán Menor también anida allí).

¿Cuántos Chorlito Nevados Hay?

Actualmente, nos estamos asociando con Adrián Naveda-Rodríguez del Departamento de Vida Silvestre, Pesca y Acuicultura de la Universidad Estatal de Mississippi, Estados Unidos. Juntos, estamos trabajando en la detectabilidad y abundancia del chorlito nevado en el este de Venezuela. Los análisis preliminares están utilizando muestras de la temporada no reproductiva, de conteos realizados en 12 puntos en la salina de San Pedro de Coche.

Modelamos la relación entre la probabilidad de detección y la temperatura del aire, tiempo del día y la distancia a las pilas de sal. Incluimos covariables para la cantidad de perros salvajes, caballos y mineros de sal al modelar la abundancia. La probabilidad de detección se vio afectada negativamente por la distancia a las pilas de sal (0.49, IC 95% = 0.49-0.5). La abundancia no se asoció con la presencia o abundancia de animales domésticos ni actividades de extracción de sal. Estimamos que había 96 (95% IC: 46-201) y 116 (IC 95% = 61-220) Chorlito Nevados en febrero y diciembre, respectivamente. Esperamos poder presentar esta información en la próxima reunión del NAOC y publicarla posteriormente en alguna revista científica.

En agosto de 2019, nuestro grupo participó en la conferencia internacional de BirdsCaribbean en la isla de la Guadeloupe, y en noviembre de 2019 en la Reunión del Grupo de Aves Playeras del Hemisferio Occidental, en Panamá. Allí presentamos los avances de nuestra investigación, y las maneras en que involucramos a las comunidades en este proyecto.

Un Esfuerzo Comunitario

Nuestra asociación con la comunidad ha continuado más allá de las excursiones de la escuela. Recientemente, creamos un mural único inspirado en las aves en la escuela de la comunidad “La Uva” que, por supuesto, incluía representaciones del Chorlito Nevado y el Charrán Menor. ¡Es realmente un trabajo hermoso!

Una de las razones para trabajar en esta región es promover la integración de comunidades que históricamente han sido apartadas de la ciencia y la conservación. En busca de mejorar esta situación, estamos llevando a cabo actividades dentro de este proyecto que integran y dignifican a la comunidad local, y también reconocen la cosmovisión de los habitantes sobre la diversidad biológica de su isla.

Desde el comienzo de este proyecto, entendimos que para proteger la salina y otros lugares de la isla, es necesario trabajar de la mano con los lugareños. Estamos muy agradecidos con la dirección del municipio escolar Obteniendo todos los detalles perfectos en el mural.de Isla de Coche, que nos ha permitido trabajar con las instituciones educativas; así como con el Liceo Napoleón Narváez y los jóvenes de 9no grado, y docentes de varias instituciones educativas por su receptividad y compromiso. Hay muchos miembros de la comunidad que han abierto sus puertas y corazón a este proyecto y a nuestro equipo: Antonio Ros, Daniel Serva, Oscar Riera, Jose Gonzalez, Jesus Escalona, JC Fernández Ordoñez.

Pueden surgir muchos obstáculos al ejecutar un proyecto de esta magnitud en Venezuela, pero gracias al apoyo constante de BirdsCaribbean estamos logrando nuestros objetivos. Es muy importante llevar a cabo este proyecto que nos ayudará a comprender mejor la población del chorlito nevado en las islas del Caribe venezolano. Para mí, es un pájaro hermoso, muy peculiar con hábitos muy interesantes. Afortunadamente, en Venezuela todavía se puede observar con mucha frecuencia en algunos lugares. Poder decir que hay una colonia reproductiva en la Isla de Coche y que permanece hasta el día de hoy es una luz de esperanza frente a la crisis ecológica mundial.
