David S. Lee was a pioneering naturalist and conservation biologist who helped get BirdsCaribbean started nearly 30 years ago, and 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 an annual grant for innovative projects that protect Caribbean birds and their habitats.
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 Groups 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.
The first call for proposals for proposals has been announced (deadline 15 December 2016) click here for information on how to apply) and the first award will be made in early 2017.
At the BirdsCaribbean meeting in Kingston, Jamaica in 2015, 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.

On the evening of April 27th, the Dreamcatcher’s captain, John Duke, and I sat at the 75-foot schooner’s large, wooden, galley table. With the sun setting over our research vessel, we studied charts and made final adjustments to plans that had been years in the making. We sailed out of Key West on the 26th, following the Florida Keys north, our schooner efficiently loaded with food, water, gear, and materials for the expedition. At sunrise we would set out and cross to Bimini, entering the infamous Bermuda Triangle. By the 29th we would clear Bahamian Customs in Freeport.
The five week long, 900-mile round-trip expedition would take us to the far reaches of the Bahama’s northern islands, including Grand Bahama Island, Great Abaco, the Atlantic Abaco Cays, and the Berry Islands. Anchored out, the nighttime sky was clear and endlessly full of constellations not easily seen from land. For me, sleep off the Florida coast tonight would be difficult, but essential. The dream was actually happening. At sunrise, with the invaluable partnerships and cooperation of so many, Conservian’s 2016 Bahamas Shorebird Conservation Expedition would, at last, become reality.
Conservian’s mission is to conserve coastal birds and their habitats throughout the western hemisphere. The Bahamas archipelago is comprised of more than 700 islands and cays, and thousands of miles of sandy shorelines, sand flats, mud flats, and mangroves, possessing prime habitat for migratory and breeding shorebirds, much of it yet unexplored. Even now in 2016, as human-created pressures increase globally, very little information exists on many species of shorebirds in the Bahamas, particularly solitary beach-nesting birds like the Wilson’s Plover.
Why should anyone be concerned about such species? Well, the Wilson’s Plover can be thought of as a “canary in a coal mine” or species that indicates the diversity level of a specific coastal habitat. To thrive, the Wilson’s Plover, much like the endangered Piping Plover, needs healthy coastal habitats that are protected from human-caused disturbance. Plovers are fairly resilient and do well if provided with a safe stretch of coastal habitat to hatch nests and raise young. Protection for plover species can also act as an “umbrella” to benefit other coastally-dependent species.

The seedling concept for Conservian’s shorebird habitat conservation work in the Bahamas had taken root in 2011 during face-to-face discussions with Bahamas National Trust and other partners at the BirdsCaribbean International Conference on Grand Bahama Island. Later that year the Dream Catcher partnership began with Captain Duke’s idea of a live-aboard expedition. In 2014 LightHawk funded Conservian’s Bahamas aerial surveys that provided essential habitat data necessary to begin on-the-ground work. Discussions and planning continued through 2015 at the BirdsCaribbean Conference in Jamaica, where Conservian was invited to present a vision for new shorebird conservation work in the Bahamas. Resulting partnerships led to a cooperative Neotropical Migratory Bird Conservation Act grant award which will help fund the project through 2017. The International Conservation Fund of Canada is also a key supporting partner of Conservian’s Bahamas conservation work.
With the start of our expedition Conservian and partners would begin the first program in the Bahamas to implement on-the-ground protective measures to limit human-caused disturbance to beach-nesting birds, and initiate control of invasive Casuarina pine at key shorebird and seabird sites. We would accomplish these goals by working together in the field with our local partners and community members to conserve the Bahamas coastal treasures.
Designed in 1996 by Captain Duke, the Dreamcatcher schooner, our home and floating field station, proved, as planned, the most efficient way to transport our crew, field equipment, and materials throughout the northern Bahamas archipelago. Solidly built of steel, she made a perfect expedition vessel. Her 20-foot beam provided great stability in open waters, yet her shallow, 5-foot draft allowed us close approach to our targeted landing areas. For ferrying field crew and equipment to shore we towed a traditional, custom-crafted, 30-foot, wooden longboat, the “Aida”, built by Captain Duke.
The expedition was planned for the month of May. After our three-day Atlantic crossing with only essential sailing crew, each week saw a new volunteer field team fly into Bahamian airports to join the project. The first team member, and one of our expedition photographers, arrived on Sunday May 1, followed by our first week’s crew on Monday at Freeport International Airport. Conservian’s team and ship’s crew adapted quickly to shared onboard duties of cooking, cleaning, and sailing.
Each morning, we’d awake early to the welcome aroma of the Captain’s freshly brewed coffee along with views of golden sunrises, open horizons, and almost impossibly vibrant turquoise water surrounds. Each night and each following morning, Captain Duke and I, along with first mate Andrew, would review planned navigation routes and logistics for the schooner and longboat, as well as deployment and retrieval plans for field crew and equipment.
Key elements of our mission on every island we visited centered on conducting surveys for beach-nesting bird target species and habitat assessments for human-caused disturbance. In planned areas, we posted signs to alert beach-goers to the presence of beach-nesting birds to reduce disturbance to birds, nests, and chicks. We made new friends wherever we went as the Bahamian locals were very interested in our expedition, desired to help, expressed appreciation, and discussed the future.
During survey work, we typically divided into smaller field teams of two or three, to cover the maximum area possible. Reaching shorebird sites, first by water and then by land, often proved to be our toughest daily task. Challenges began with finding suitably calm waters for team drop offs.
To reach potential habitat on islands with Atlantic beachfront, we often hiked on overgrown trails, through vegetated terrain, and across rocky shorelines. We made use of a variety of land-based transportation modes, from rental van and taxis to hitch-hiking on local golf-carts.
We walked many miles enduring May’s tropical heat, humidity, and biting insects while searching for beach-nesting birds or posting shorebird sites. Rewards, were abundant, however, with exciting new data collected, new shorebird sites posted, frequent nest and chick sightings, and unforgettable vistas of Caribbean sands and seas, as well as an occasional quick dip in the blue to cool off. Often when the Dreamcatcher was anchored off shore, our adventurous and productive days ended with a boat-side swim or snorkel in the clear, near-shore waters followed by a hearty meal from the galley, or on-deck barbecue, jointly prepared by the group.
We conducted ground surveys for beach-nesting birds on 29 islands and cays, collecting new data on habitats, and breeding abundance and distribution. Local volunteer stewards participated in ground surveys and assisted with posting and signing of imperiled shorebird areas. Noted conservationist Erika Gates and her dedicated volunteers joined us aboard the Dreamcatcher for a sign posting mini-expedition to protect Bridled Terns at Peterson Cay National Park, where Conservian also conducted Casuarina eradication. On Grand Bahama Island and Great Abaco, by invitation, we gave educational presentations, speaking about Conservian’s shorebird work and the expedition.
With assistance from Ellsworth Weir, manager of Lucaya National Park, we conducted a pilot project to control the invasive species Casuarina pine, which has spread throughout the Bahamas eroding beaches and destroying shorebird habitat. Conservian provided in-the-field Casuarina control training for staff from the Bahamas National Trust and Bahamas Public Parks and Beaches Authority. Our local Casuarina control team began eradication at Lucaya National Park’s Gold Rock Beach with herbicide donated to the project by Dow AgroScience.
Conservian’s Bahamas cooperative shorebird conservation work is a new and innovative program with long-term objectives for conserving and protecting the natural coastal resources of the Bahamas through directed assistance and local capacity building. With essential support from our partners BirdsCaribbean, Bahamas National Trust, local volunteer coordinators Erika Gates, Honorable Pericles Maillis, Dr. Elwood Bracey, Shamie Rolle, and many others, we were able to accomplish major project objectives during our first year of the project. Our present and future successes are attributable in great measure to our increasing family of supporting partners, whom we look forward to working with again soon.
In May 2017, Conservian/Coastal Bird Conservation will embark on our second Bahamas conservation expedition in the northern Bahamas.

Steffen Oppel from the UK’s Royal Society for the Protection of Birds (RSPB) recently visited St. Lucia to assist the Department of Forestry with setting up bird counts in order to search for the elusive Semper’s Warbler. This is his story.
An artist’s rendition of the Semper’s Warbler – the last confirmed sighting was in 1961. (Joseph Smit [Public domain], via Wikimedia Commons)The Semper’s Warbler (Leucopeza semperi) is a small songbird endemic to St Lucia, but sadly the species has not been seen with certainty for more than 50 years and may be extinct. In 2003, at the BirdsCaribbean (then known as the Society for the Study and Conservation of Caribbean Birds) meeting in Tobago, forester Donald Anthony from St. Lucia reported on his efforts to find this warbler. He said that a few years ago, he saw what he could only describe as this bird somewhere on one of the Pitons. His efforts subsequent to that turned up nothing.

Martin Frost believes he saw a Semper’s Warbler in the early 1990s. This triggered several trips by Martin, Edward Massiah and forestry guides to find the bird in the mid-1990s. Although they were not able to detect the warbler, they never gave up hope that it still exists, noting that there are some very hard-to-access areas that are never visited by humans, and would take days to explore. Edward commented, “If you assume this bird is shy and possibly even ground-dwelling and very local then it is possible it has not yet been located.”
Fast forward to 2016. Unconfirmed reports of warbler sightings continue to trickle in, even as recently as 2014 and 2015, but there have been no major efforts to search for the bird despite a lot of interest in carrying out more searches. With such an appealing subject and always up for a challenge, I was sent to help give our St. Lucian friends the tools to search for one of the country’s rarest species.
Need for a proper search

Numerous invasive species introduced by humans, such as rats, cats, and mongooses, roam freely around St Lucia and unfortunately these skillful predators have caused the extirpation of some of the island’s endemic species. However, the Semper’s Warbler is a small, nondescript brownish warbler that hops around the floor of St. Lucia’s dense rainforest, and for this reason it may be easily overlooked. Given also that St Lucia still has extensive tracts of seemingly intact rainforest where the species may persist, it would be foolish to write off the Semper’s Warbler without conducting a systematic search.
The rainforest on St Lucia is so extensive and rugged that a proper search for this tiny, secretive bird would require a little more than just a weekend of intensive birding. Until now, it was not known how long the search would have to be, or what manpower would be required. Therefore in April 2016, my colleague Lyndon John and I facilitated a workshop on St. Lucia to determine the effort needed to search for the Semper’s Warbler.

Together with experienced and enthusiastic rangers from the Department of Forestry, we first pored over maps to identify suitable habitats where the species might still persist. We then slogged through rugged hills to assess the feasibility of sufficiently covering the remote areas where intact rainforest still remains. After two weeks, we concluded that a proper search would likely require 84 days to search ten priority areas covering the most natural rainforests on St Lucia. This means that the search team will need to be skilled and hardy, able to cope with venomous snakes, rugged terrain, and will need to use equipment such as mistnets, sound recorders and camera traps to comb the hills for this small and elusive bird.

During the workshop, we established 20 permanent sampling stations in order to count birds. Conducting regular annual surveys of all forest birds might increase the chance of detecting a Semper’s Warbler while also providing valuable information on other endemic species that are still more common, such as the St. Lucia Black Finch (Melanospiza richardsoni), the St. Lucia Oriole (Icterus laudabilis), or the White-breasted Thrasher (Ramphocinclus brachyurus).

While no Semper’s Warblers were detected during our field work, the team emerged inspired and hopeful that the species may still persist in some of the remote valleys and ridges off the beaten paths of St. Lucia’s lush interior. Forestry Officer, Pius Haynes remarked, “We at the Forestry Department in St. Lucia are highly confident the species may still persist in some remote pocket of our rainforest. The rediscovery of the iconic Semper’s warbler would be a remarkable thing as it would boost our conservation efforts and showcase the value of our native biodiversity. The Forestry Department in St. Lucia was very happy to collaborate with the RSPB in executing a training workshop aimed at developing a feasible strategy to undertake searches for the Semper’s warbler. We were also very happy to receive much needed technical assistance and equipment to better undertake bird surveys. We are confident that the training and equipment received will go a long way in assist us in our quest to rediscover the Semper’s warbler.”

Back in 2005, I first visited St. Eustatius on vacation. I was living in Amsterdam at the time and thought I’d give one of the lesser known Dutch Caribbean islands a try. Vacation turned into a ‘year off’ when I decided to return to the island in 2006, and that year off has since turned into a career in ecology, a house, a partner, and a child in 2016. The island has a way of grabbing hold of your heart—I had fallen in love with the way of life here, unhurried and unspoiled, and also the island’s inhabitants—namely its Red-billed Tropicbirds.
St. Eustatius, affectionately known as Statia, is a small landmass with a big history. Famous (but not well known) for being the first foreign nation to recognize the United States of America’s long sought-after independence in 1776, the island reached its economic peak around 1795. Each year, thousands of ships anchored on the roadstead of Oranjestad, and the shore of the Bay was lined with hundreds of warehouses packed with goods. In fact, more trade (both legal and illegal) transpired here after the end of the American Revolution than on any other Caribbean island.

But we are here to talk about birds, seabirds specifically. As the eighteenth century drew to a close, St. Eustatius gradually lost its importance as a trading center and most merchants and planters left the island. Through the nineteenth and twentieth centuries, Statia became and remained a quiet island. In contrast to the rapid and excessive environmental destruction that has ravaged many Caribbean islands in their quest for economic development, the coastlines of Statia have remained untouched by high-rise hotels or boardwalks. This means that, despite its small size, the island has become one of the main nesting sites for Red-billed Tropicbirds in the region (Saba and Little Tobago being the others).
In 2012 I participated in a tropicbird monitoring workshop on Statia, led by Dr. Adrian Delnevo and facilitated by the Dutch Caribbean Nature Alliance. That same year I also attended an international training workshop for seabird research and conservation on San Salvador, the Bahamas, organized by BirdsCaribbean, Clemson University and Defenders of Wildlife. It was then that I realized the increasing vulnerability of seabirds and the importance of better understanding their threats and population dynamics. I also learned field techniques for monitoring and studying seabirds in these workshops. So, in 2012, together with former intern Andrew Ellis, and employed by STENAPA, the local conservation NGO, we embarked on a mammoth quest to find the island’s main nesting sites. We initially only knew that tropicbirds nested along Zeelandia Beach, which faces the Atlantic Ocean, because we could see them inside crevices in the cliff face. But where else did they nest?
Some call me a wuss for wearing gloves but I am rather fond of my fingers.
According to earlier published literature, there were estimated to be only 30 pairs of Red-billed Tropicbirds on Statia (Lee and McGehee, 2000). This was followed by EPIC’s estimate of 100-200 pairs in 2003. Having traversed the entire island in search of nests during 2012-2013, however, we believe the population more likely totals around 300-500 pairs. To our surprise, the main nesting site was not Zeelandia Beach – in fact we realized this was one of the worst habitats for tropicbirds due to erosion of the sandstone cliff. After clambering over giant boulders along Statia’s north-west coast, we finally hit gold. At elevations of just 20-40 meters above sea level, we were able to (safely) access some 85 nests along a narrow strip of coastline spanning approximately 1km. While there are many more nests at higher elevations, our lack of levitation prowess prevented us from accessing those.
My youngest and most entertaining field tech (aka my daughter, Lalia), who apparently enjoys rock climbing and retrieving angry birds from nests.
And so, since 2012, from mid-October to mid-May, we have faithfully monitored this magnificent seabird. We measure, weigh and band adults and chicks and record nest success. Sticking your hand into the nest of a ferociously angry and defensive tropicbird’s nest may not sound like fun to some, but I like to think my family would be proud. I have become accustomed to the joys of regurgitated fish, pooped-on pants, and new scars after every visit. When my daughter comes home from school I show her my new collection of scrapes and bites. She has even joined me on fieldwork (see photo) and is now the go-to person at school for anything nature-related.
Since 2012 we have banded about 450 tropicbirds. We’ve also attached geolocators and GPS loggers to a few individuals, with varying rates of retrieval success. We have learned that they can travel great distances inside and outside the breeding season, and we now have a better understanding of the threats they face (mainly rats, which prey on eggs and young), but this is just the beginning. As I write this, we are submitting a proposal to further study Red-billed Tropicbirds on Statia and Saba. If approved, I will spend another four years doing my PhD on this enigmatic species. Being able to contribute to regional knowledge and the long-term conservation of this beautiful bird is a worthy endeavor and well worth the battle scars. I am grateful for the exciting opportunities that have allowed me to stay on Statia and study Red-billed Tropicbirds; hopefully my Caribbean seabird journey will continue – stay tuned!

This story begins with a couple of biologists, from Montana and Winnipeg, meeting by chance in Hawai’i, and ends in Grenada – though this is an ending that is really a beginning. In this blog I’m going to focus on a banding project that students and I started in November 2015. But first, to really appreciate the serendipity that brought us to this point, I have to tell you about how I, a conservation biologist from the University of Manitoba, came to this little paradise.
At The Wildlife Society conference on Hawai’i in 2011, I hoped to catch a glimpse of some of the endemic species that generally avoid the resort-laden perimeter of the island, so when I overheard another attendee asking where she could go to see birds, I introduced myself. We decided on the spot to rent a car together to check out the island, and spent a delightful day snorkelling and visiting local coffee plantations. I had had the good luck to meet Dr. Andrea Easter-Pilcher, a professor who was originally from Montana, and now teaches at St. George’s University (SGU) in Grenada. Andrea is also an active member of BirdsCaribbean and was on the organizing committee for the 19th Regional Conference held at SGU in July 2013. During our drive we hatched a plan to bring Canadian students down to Grenada, which in 2014 was realized as a field course (we will be returning for another field course in 2017).
Belmont Estate, one of our banding sites in Grenada, is a unique and authentic 17th century plantation that offers guests an opportunity to participate in and observe the workings of a fully functional historic plantation, growing spices, cocoa and more.
This collaboration has naturally developed further into a fledgling research program. In April 2016 we will be starting our first big field season, with 3 graduate students starting or continuing different projects. However, we initiated this program in November 2015, when we started a mist-netting and banding project focussing on passerines and near-passerines in three sites spread across Grenada’s rural habitats.
Myself, four graduate students (Paulson Des Brisay, Chelsea Enslow, Alexandra Heathcote and Christoph Ng) and Paula Grieef, bander-in-charge from Oak Hammock Marsh, Manitoba, participated in the initial banding period. We were welcomed with open arms by our amazing partners. Initially we stayed with Claudette David (of SPECTO, an environmental NGO) at High Hopes Villa in Bathway. We had the most wonderful time getting to know Claudette and many additional volunteers and staff from SPECTO. We mist-netted and banded in gardens, orchards and cocoa plantations both at High Hopes and at Belmont Estates, an award-winning organic plantation and agri-tourism destination nearby. Shadel Nyack Compton, owner of Belmont, and her staff were just as welcoming as Claudette. Finally, we moved to a more southern cocoa and mixed-species plantation at a small farm in St. David, where we had the pleasure of working with Shelley Roberts and Phillip Patrick of Little Cocoa cottage.

In November we banded 244 individuals of 14 species, including Lesser Antillean Tanagers, Antillean House Wrens, Lesser Antillean Bullfinches, and many other passerines of forest-agriculture ecosystems. Even though we only banded for a couple of weeks so far, we have found interesting results. Between 50 and 100% of the individuals of every species we captured were in active moult, a much higher rate than we expected in November. Many species showed morphological differences relative to other populations that have been reported in the literature. We are really excited to be back banding in April and May this year, so that we can increase sample sizes, compare body condition between rainy and dry seasons, and get a better handle on moult and breeding periods.
Christoph Ng laughs with Jody Daniel, instructor at SGU and former student of both Andrea Easter-Pilcher and Nicola Koper, and a SGU marine, wildlife and conservation program student, while releasing banded birds.
We also contributed to the training of a class of students, taught by Dr. Miya Warrington, at St. George’s University. Miya’s class in ecological methods joined us at Belmont Estates and learned about mist-netting and banding a variety of different species. We have many plans to collaborate further with SGU to work towards learning about and conserving many of Grenada’s bird species. Our research lab group has already included two Masters students who are graduates of SGU’s marine, wildlife, and conservation biology program (Ezra Campbell and Jody Daniel, who served as Chairs of the organizing committee of the 2013 BirdsCaribbean Conference), and we have plans to integrate more SGU students and grads into our research activities. This has been a great opportunity to increase the international composition of the University of Manitoba’s graduate programs, while also contributing to the education and training of Grenadians.

One of the best parts of the trip was realizing how interested the local community members are in conservation of their birds. In St. David, lots of locals stopped to chat as they saw us banding near roads, and offered us encouragement for our work. Claudette and several of her staff, especially Valdon Paul and Shaundel Franklyn, participated in many of our banding activities, and showed great delight in seeing many different species up close. Shadel and her staff were also really engaged in our research, and were grateful that we chose to work at Belmont – indeed, this collaboration has been so wonderful that we’ve planned to collaborate further this year, participating with them and their visitors on activities for the 2026 Caribbean Endemic Bird Festival, as well as further banding. This response makes me even more excited about our research and our ongoing collaborations with Grenadian communities, and I continue to be grateful for the fates that brought Andrea and I together on that lucky day in Hawai’i. Stay tuned for more reports on our findings from the Spice Isle!

With a title like that, I’m hoping that many of you instinctively hucked your laptops across the room, sprinted out to the barn and started hitching your pride-and-joy appaloosa to the covered wagon your grandpappy gave to you as a belated wedding gift back in the summer of ‘69. Just don’t forget the “caulk the wagon and float” option if you’re coming from the mainland.
If you decide to make the journey, I suggest making landfall on the beautiful island of Hispaniola (gold deposits have all but dried up in Jamaica – but more on that later). Trade in your bikini and flip-flops for some long pants and hiking boots, because what you came for can only be reliably found high up in the mountains. Not that I like to give away too much insider advice, but if I were you, I’d keep heading up until you’ve reached the Hispaniolan pine forests – the highest altitude forest type you’ll find on the island. Find a grassy clearing, sit down, and wait, because at this point, the gold is going to come to you! With mighty wings (~11cm long each), fearsome talons (actually you’d have to strain to even notice the legs on this bird), and a relentless hunger for meat (prey doesn’t get much bigger than an 8mm march fly), watch out as the infamous Golden Swallow comes tearing over the nearest hillside radiating its majestic golden sheen across the lands…wait…wait…I can’t do this anymore. It’s a tiny bird that can’t peck to save its life, and unless the light of a passing-by solar flare manages to reflect off the swallow’s dorsal plumage at a perfect 47.86o angle, the bird is green!

In 2010, in collaboration with the Golondrinas de Las Américas (Swallows of the Americas) project at Cornell University, researcher Jim Goetz and Dominican biologists Esteban Garrido and Jesus Almonthe erected nearly one hundred artificial nest-boxes across a national park known as Parque Valle Nuevo (Parque Nacional Juan Bautista Pérez Rancier) located in the Dominican Republic’s Cordillera Central. Their hope was to attract a sizeable, returning population of breeding Hispaniolan Golden Swallows (Tachycineta euchrysea sclateri) to those nest-boxes so that a formal study of the species could be carried out. By 2012 the plan had worked, and word spread back to Cornell that the time was ripe to find someone to undertake the research. Upon hearing about the opportunity – and conveniently in the very beginning planning stages of my master’s thesis – I decided to give it a go. I was fresh off two years of back-to-back-to-back field seasons working with Tachycineta swallows up and down the Western Hemisphere, and I was ready to find out where else this genus of acrobatic aerial insectivores could take me.
The Hispaniolan Golden Swallow, it turned out, was considered endemic to the island, threatened, and in steady decline. Furthermore, there was so very little known about it. Some work had been done with a very small breeding population that was nesting in crevices within the walls of abandoned bauxite mines located in the Aceitillar region of the Sierra de Bahoruco, but that was really about it. As I came to realize both the extent of what we didn’t know as well as the current plight of the species, I decided that a focused study of the swallow’s breeding biology would simply not be enough. The project would have to be more holistic. The work I decided to do would have to be chosen for its relevance and thus its ability to produce information that helped develop both short and long-term conservation management plans for the species. The project could only truly be successful if its every facet was geared towards having a broader impact on the future of the Golden Swallow. So, I had three years (roughly speaking – this is academia we’re talking about) to make some magic happen, and with the laundry list of ideas and goals growing daily, I knew I was going to need some help. Much to my good fortune, I found smiling faces and willing bodies around absolutely every bend in the road. [All of those people, groups, and foundations deserve their own article – and I plan to write it – but in the meantime let me just say that I’m hoping we all set some kind of record for the 400 word acknowledgment section within our Hispaniolan Golden Swallow monograph that’s currently under review for publication by the JCO.]

And so we set out on an adventure of a lifetime with the underlying goal of studying a bird and using what we learned to help save that bird, while simultaneously nourishing an already burgeoning sense of local stewardship over Hispaniola’s feathered friends and the habitats they so deeply depend upon. We set the bar high from the beginning, and I can be honest in saying that I feel good about what we accomplished and where the project stands today.

However, as opposed to trying to tackle an impossible play-by-play of what transpired over those next three years (thankfully all of that information is in my master’s thesis and can be yours for just three easy payments of $29.99), I’m going to take a slightly different approach. I’m going to share with descriptions of images (and feelings) that go through my head when somebody kindly asks me, “So how’d that Golden Swallow Project go?” Little does that person know how much weight a question like that can have, or how it causes me to temporary black-out as my mind boards a high-speed emotional (and perhaps somewhat spiritual) roller-coaster from which there is little hope for return for at least the ensuing two minutes. So let’s go for a ride.
My wife, Marisol, and I are inside of a rental jeep that hasn’t had a tune-up since Elvis left the planet. It’s 10pm (pitch dark), and there is a rather large gathering of people around us. Some are cheering, others look nervous. We are momentarily stopped, looking out in front of us at a raging river flowing out of a stormy valley. The road, of course, stops at one side of the river and continues again on the other side. That “other side” is our only way home, back up into the mountains after having endured a long day of re-provisioning our food supplies down in town. It’s been an intense first field season so far. There have been high highs and some low lows. We really want to get back up to the cabin where we’ve been living, because field work awaits us again at 6am the next morning. Against my better judgment, we begin moving forward and into the river. Despite the water starting to come in through the driver’s side window, the four-wheel drive seems to be working well, and a grin starts creeping onto my face. That grin disappears quickly when all four tires stop making contact with the gravelly bottom of the river and the current begins carrying us downstream.

in the hand. My rule is to keep her no longer than two minutes, during which time I’ll need to take at least four different biometric measurements, describe her plumage, and place an aluminum band on her leg. That doesn’t leave much time to just admire. But a few seconds turns out to be just enough.
I look at one of our 200 artificial nest-boxes (we expanded considerably our first year) and realize how simple it is. Yet, at the same time, it’s the solution to everything. First, the box provides a nesting cavity for swallows in a habitat where otherwise very few natural cavities exist, which results in more nesting attempts by more pairs of swallows. Second, with the boxes attached to free-standing poles, a predator guard in the form of a metallic cone can be fashioned below the box to thwart attacks from invasive rats and mongoose (not to mention those damn feral cats!). This results in higher rates of brood survival in the face of unnatural – and overwhelming – rates of predation and subsequent nest failure. Third, the boxes are built to be temporarily opened from the side by researchers studying the breeding life history of the swallows. This provides us access to a nearly limitless wealth of data. Fourth, the boxes are tangible, visible, and accessible. These are perhaps the most important features. The box itself becomes a curiosity, a talking point, and ultimately an icon for our collective efforts to protect and care for nature. Although maybe not the long-term answer, the nest-box is invaluable for now.
My field crew today consists of two Dominicans, one Haitian, two Argentinians, one Cuban, and one Venezuelan. It wasn’t necessarily easy, but we got them all here. Cross-culture-pollination is the bread and butter of great science and conservation work. Amazing how quickly good solutions come in an environment like this.

Josh LaPergola – the legend that studies Hispaniolan Woodpeckers in Jarabacoa – has come to visit me up in Valle Nuevo. He’s brought his entire field crew along with him in an attempt to help me piece together the riddle of why there are so few woodpeckers (and thus cavities that my swallows can use to nest in) in the high-altitude pine forests where I am working. We spent the last two days hard at work, so this evening I’m treating the group to a dip in the upper pool of Aguas Blancas, one of the best waterfalls on the island. Anyhow, Josh does a mean cannonball off the nearby rock face (perfect execution by the way), surfaces a few seconds later, and casually admits that he forgot to take his glasses off before he jumped in. Though the story only goes downhill from there, our admiration for Josh grew stronger that day as we saw in him an inhuman level of determination as he nearly went hypothermic (yes, that water is unforgivingly cold) by repeatedly diving down into the zero-visibility abyss trying desperately to save the fate of his summer. [A big shout-out to Josh, who just unfortunately suffered a serious accident during his 2016 field season, but is currently managing to push through a difficult recovery with nothing but a smile on his face. All our best buddy, we’re thinking of you!].
My field assistants and I sit down in front of an evening fire with the local park guards in Valle Nuevo. They

are bursting with energy, interrupting each other to tell me stories about the Golden Swallows they saw while making their rounds that day. One man says that he’ll give his life for those birds. I laugh, but make sure to grow a little more serious when I tell him that that’s not totally necessary…just in case. At the end of the night, I walk back to the cabin realizing that really well-done outreach takes your passion and makes it contagious.
I’m sitting at my office in Ithaca, NY in August, post field-season, and receiving a flurry of emails that Parque Valle Nuevo is burning. A forest fire spreads rampantly across the national park, directly through the areas where all of our nest-boxes are located. Everything is lost.
Not much later, I’m sent a flurry of photos that indicate otherwise. Because the nest-boxes are all mounted on metal posts in meadows away from the forest edge, the fires in those areas have burned low to the ground, passing quickly underneath them. The nest-boxes, in many areas, are the only things left standing. Though a few were lost, word soon comes back to me that they have been replaced. The project carries itself without me – a major success for everyone and a solid indication that many more good things are to come!
As my vision begins to clear, I know all-too-well what I’ll hear next…
“Whoa, sounds like an adventure! So, tell me, what are your plans for a PhD?”
[My vision goes dark again…]

In 2014, I conducted my last full field season in the Dominican Republic (in other words, I had burnt up all of my NSF funding and the winds of change were blowing my wife and me from Ithaca down to Raleigh). That being said, I was (and still am) extremely passionate about Golden Swallows, and more and more so about aerial insectivores throughout the Caribbean (swifts and swallows of course; those flycatchers and nightjars will have to find other sponsors). I did, however, have the pleasure of sneaking in one more (big) Golden Swallow adventure before my master’s defense came around. I was asked by Gary Graves, the Curator of Birds at the Smithsonian National Museum of Natural History, to finish the long-running census work he had been carrying out in Jamaica in search of the critically endangered Jamaican Golden Swallow (T. e. euchrysea) – the only other known race of Golden Swallow and one that hadn’t been reliably seen since the 1980’s. Gary had scoured the island except for two places the Cockpit Country in the northwest and the Blue Mountains in the southeast.
I had never been to Jamaica before, and judging by its miniscule size relative to Hispaniola on a map, I figured I could probably walk across that island in a day. Easy. Well, Proctor men have been wrong before, which means it was bound to happen again. It turns out that remote census work in Jamaica was more physically demanding (by far) than anything else I’d ever done in my life. Luckily, with unwavering field assistants at my side (Seth only collapsed vomiting from the stress twice, mind you, and John only plunged off a cliff once), we hacked our way across as many miles of that terrain as we possibly could in two months’ time. Remember earlier on when I mentioned “gold” being scarce in Jamaica. Unfortunately, that’s the truth. By the end of our work, and in light of compounding evidence in favor, we made a formal declaration that the Jamaican Golden Swallow was indeed extinct (look to Volume 29 of the JCO!). Despite not finding our search target, we were able to document many other interesting behaviors exhibited by the swift and swallow species that still inhabit the island. Furthermore, the extinction of the Jamaican Golden Swallow race brings considerable perspective to the importance of the conservation efforts surrounding the remaining race in Hispaniola.

I think that there is a slow, but powerful momentum growing behind the idea of conservation in Hispaniola, and I’m hopeful that the work that so many of us have put into the Golden Swallow Project will continue to help that movement grow. So I encourage all of you to put the mountains of Hispaniola on your bucket list – they won’t disappoint. Maybe there will be a little bit of gold waiting there for you when you arrive.
Your Caribbean Gold Digger,
Justin Proctor
PS. An afterthought – I want to encourage birders and ornithologists (especially those that have somehow made their way through the entirety of this blog post) to pay a little extra attention to aerial insectivores during your future outings, and to document what you see by entering your observations in eBirdCaribbean. We are going to need all the information we can muster in order to grow our information banks strong enough to better diagnose – and do something about – the causes behind the growing, widespread trend of aerial insectivore decline in North America. For many of these species, a little bit of information goes a long way. Thank you!

The sandpiper flocks fly up in waves, blurred wings beating and gliding as one, they circle around after being flushed and land again in unison on the dike road ahead of us while another flock lands just behind us. “Ok, start counting!” I say to my colleague, Fernando Simal. Easier said than done! The little brown birds dart about constantly on land and at the water’s edge, deftly snapping brine flies off the ground. We do our best to count the number of birds of each species using tally counters and record the numbers on our data sheet. This particular flock was composed mostly of Least Sandpipers and Semipalmated Sandpipers with a few Sanderlings thrown in.

Fernando and I are at our one of our “high density” points (counting stations) on the Cargill Salt Production Facility in southern Bonaire. We are driving the dike roads stopping every 400m to carry out a 6-minute count, recording all the birds in a 200m radius around our point. A second team, Jeff Gerbracht (Cornell Lab of Ornithology) and Binkie van Es (St. Maarten Nature Foundation) are covering another part of the facility. The conditions can only be described as harsh—non-stop winds of 25-30 knots, blazing sun and salt foam blowing at us constantly. But the shorebirds love it, and so do we—there are not very many places where you can see such large concentrations and diversity of shorebirds so close.
We have so far encountered over 20 species of shorebirds and waterbirds using the Cargill ponds, including American Flamingo, Great Blue Heron, Tricolored Heron, Reddish Egret, Black-bellied Plover, Snowy Plover, Greater yellowlegs, Lesser Yellowlegs, Ruddy Turnstone, Stilt Sandpiper, Least Sandpiper, Semipalmated Sandpiper, Western Sandpiper, Short-billed Dowitcher, Red Knot and more. Depending on where the point is in the Cargill Facility, we might encounter zero birds in areas of deeper water, or mixed flocks numbering in the hundreds or even thousands in areas with shallow water or exposed flats.

The prime attraction to this habitat is food—some of the ponds team with brine shrimp or brine fly larvae and the dike roads separating crystallizer ponds are often covered with hordes of brine flies. These small organisms, adapted to thrive in extremely salty conditions, serve as an essential food resource for these wintering and migratory shorebirds.
This is the second year of intensive surveys conducted at Cargill in an effort to learn more about the species and numbers of birds using this site. Shorebirds have received much attention in recent years due to evidence of alarming hemispheric-wide declines in numbers. Loss of wetland habitats is one of the main threats, but other factors also play a role, such as hunting, human disturbance, impacts from climate change such as sea level rise, and predation from invasive species.
In the case of the Red Knot, a threatened shorebird, numbers plunged from 90,000 to 15,000 from overharvesting of Horseshoe Crabs in the Delaware Bay in the early 2000s. The Bay is a critical migration staging area in spring where as much as 90% of the Red Knot population congregates to feast on horseshoe crab eggs. These birds rely on the eggs as a vital food source at their final stopover to build up enough fat and energy to make it back to their breeding grounds in the Arctic. They arrive in Delaware Bay in mid-May weighing about 120 grams, and depart 2 weeks later weighing 180 grams or more, with one particularly large individual weighing in at 244 grams at departure!

How and why did these surveys get started? Two years ago, I had the chance to visit and tour the Cargill Salt Production Facility for the first time, thanks to Daniel Deanda (Production Manager), who attended our Wetlands Education Training Workshop in May 2014, hosted by STINAPA Bonaire. I was amazed at the number of migratory shorebirds and waterbirds on the property, including the stunningly beautiful American Flamingos which dot the stark landscape like pink flowers. I recognized that this small island and even smaller site was probably hugely important to migrant and wintering shorebirds, perhaps even qualifying as a Western Hemisphere Shorebird Reserve Network (WHSRN) site, a program set up by Manomet 30 years ago to protect the most important breeding, stopover, and wintering habitats for shorebirds throughout the Americas.
Thanks to funding support from Environment Canada, the blessing of Cargill managers, and partnerships with local organizations STINAPA Bonaire, WILDCONSCIENCE, and the Dutch Conservation Nature Alliance, our surveys are providing estimates of population numbers of target species at the site. Although we are still refining our population estimates, there is no doubt that this site provides a winter home for thousands of shorebirds, enough to nominate it for a WHSRN site. It could also be a critical stopover area during spring and fall migration for shorebirds that are spending the winter further south. Additional counts planned for spring and fall of 2016 will help answer that question.
The Red Knot breeds in the Tundra of the central Canadian Arctic from northern Hudson Bay to the southern Queen Elizabeth Islands. It winters as far south as Tierra del Fuego at the tip of South America, undergoing a migration of 9,300 miles each fall and spring, making it one of the world’s longest-distance migrants. (Photo by Fernando Simal)
One of the most exciting finds from our 2016 February surveys were fairly large flocks of Red Knots. We noticed a leg band (green flag) on one of the birds and were able to read the flag—CTK. After entering the banding data into BandedBirds.org and corresponding further with the ornithologist that had banded the bird, Dr. Larry Niles, I learned that this bird was first captured and banded in 2004, making it a very old bird, at least 12 years of age. It was recaptured again in 2008 and May of 2015 in Delaware Bay. Larry commented: “On May 30 which is the end of this stopover period, the bird weighed only 154 g which is 26 grams short of the 180 g threshold necessary for a successful flight to the Arctic. Nevertheless this bird survived and still breeds.”
We think it is really cool that the salt ponds of Bonaire are providing a home for this Red Knot for the winter of 2015-2016, and perhaps other years as well! WHSRN site designation will help to raise awareness about the importance of “this little island” and the Cargill Salt Facility as a haven for migratory shorebirds.

“Do you see the Pelican?” Damian Whyte, environmental officer of the Urban Development Corporation, Jamaica, seems to be asking students of Swallowfield Primary School as he demonstrates how to use the telescope as a part of the Caribbean Waterbird Census 2016 in Palisadoes Port Royal Protected Area. The equipment was donated to NEPA and Jamaica Environment Trust by BirdsCaribbean (photo courtesy of Ava Tomlinson).
The first internationally coordinated waterbird count was organized in January 1967 by Wetlands International. Now entering its 50th year, the International Waterbird Census has become a vital source of information for the conservation and management of wetlands and waterbirds around the world. Seven years ago, the Caribbean Islands, under the auspices of BirdsCaribbean, formally began to contribute to the International Waterbird Census; and thus the Caribbean Waterbird Census, or CWC, was born. Every year since 2010, wetlands across the region have been visited by enthusiastic, adventure-seeking volunteers eager to observe and count waterbird populations. The CWC takes place over three weeks in January and February, and 2016 was another fantastic year.
The Caribbean is home to over 500 species of birds, 170 of which are endemic, and the region provides an important site for Neotropical migrants. Wetlands are critical for numerous waterbird species, providing a variety of habitats from swamps and lagoons to mudflats and lakes. Waterbirds depend on wetlands as a source of food or as nesting habitat. For example, one of the biggest wetlands in the Caribbean, Trinidad’s Nariva Swamp provides a vital nesting site for the magnificent Scarlet Ibis. Many species depend on wetlands for refueling and resting, especially during their long winter/summer migrations.

For some, going out into the blistering heat, getting your shoes covered in mud, and being bitten by sandflies and mosquitoes does not sound like the most appealing activity. Yet for hundreds of birders across the region, the Caribbean Waterbird Census is the perfect excuse to take out their spotting scope, camera and binoculars, grab a pen and paper, and visit their nearest wetland in search of waterbirds.
We are pleased to announce that 13 countries across the Caribbean participated in this year’s CWC, and in the cases of Anguilla, Bonaire and Jamaica more than one count was conducted by different organizations and citizen scientists. A total of 321 checklists were submitted, and despite the ongoing drought across the region, a total of 191 species and 30,406 birds were observed in 152 locations! The US Virgin Islands submitted a record 78 checklists.
The most numerous species observed were the American Flamingo (6,265), Glossy Ibis (1,372), Short-billed Dowitcher (1,320), Cattle Egret (1,121), and the Blue-winger Teal (1,107). The most frequently reported species (i.e. on the most surveys) were the Yellow Warbler (142), Bananaquit (104), Gray Kingbird (98), Great Egret (85), Lesser Yellowlegs (83), and the Spotted Sandpiper (72).
Cuba used the CWC as an opportunity to conduct a workshop on wetland biodiversity for a local community in Los Palacios, Pinar del Río (photo courtesy of Alieny Gonzalez).
The CWC is critical in understanding the distribution, status and abundance of waterbirds on a local, regional and global level, thus helping BirdsCaribbean and local governments make informed decisions on their conservation and management. The CWC also helps determine which sites are important for supporting huge populations of waterbirds, as well as the key wintering and migration stopover sites for threatened and declining species such as the Red Knot, Whimbrel, Reddish Egret, American Oystercatcher, and Semipalmated Sandpiper.
Over 240 sites are currently monitored by volunteer counters in BirdsCaribbean’s network. However, with over 7,000 islands and islets in the Caribbean, many important sites have not yet been included. The CWC and other censuses are a great way to involve local communities in citizen science and get young people more connected with the region’s unique and often threatened birds.

The salt ponds of Bonaire are providing a home for this and other migratory birds during the winter of 2015-2016. Western Hemisphere Shorebird Reserve Network site designation will help raise awareness about the importance of Bonaire and the Cargill Salt Facility as a haven for migratory shorebirds.
We are just beginning to understand how important the Caribbean is to the Piping Plover. (Photo by Matt Jeffery)How important is the Caribbean to global populations of Piping Plover? You can help us find out! Listed as threatened and endangered in the United States and Canada where it breeds, the Piping Plover (Charadrius melodus) spends a large portion of the year on wintering areas—including many in the Caribbean—and it is critical that we identify and conserve these habitats.
Right now, the 2016 Piping Plover Census is happening and you can join in. You don’t need to be a professional to help—citizen scientists with a spotting scope or binoculars and some familiarity with shorebirds are welcome to participate. You can also conduct Piping Plover counts while you are participating in this year’s Caribbean Waterbird Census. Get all the details, instructions and census tools at eBird Caribbean.
A juvenile Red Knot in Barbados (by John Webster). This species has one of the longest migrations of any bird, traveling more than 9,000 mi (14,000 km) from the Arctic to the southern tip of South America each year. Some individuals use Caribbean wetlands as stopover sites on migration.
One bird, two bird, three bird, four! Since 2010, hundreds of dedicated volunteers have been spreading out across the Caribbean’s vast wetlands, large and small, and counting birds for the Caribbean Waterbird Census (CWC). The goal is to learn more about the status of migratory and resident waterbirds and strengthen their conservation.
Waterbirds in the Caribbean, and the wetlands they depend on, are challenging to monitor. The Caribbean region is spread across 7,000 islands, islets, and cays and many wetlands are difficult to access. But our intrepid counters have braved gooey mud, marauding mosquitos, and sweltering heat to help us gather data of great importance to conservation.
Waterbirds are species that depend on aquatic habitats, like mangroves, salt ponds, tidal flats, lagoons, beaches, and freshwater marshes, to complete portions of their life cycle. Unfortunately, many species are in severe decline, particularly shorebirds. Semipalmated Sandpiper that once numbered over two million on Caribbean and South American wintering grounds have dropped by 80%. Another long-distance migrant shorebird, the Red Knot, is now listed as Threatened under the Endangered Species Act, having declined by 80% as well. The Zapata Rail, endemic to sawgrass habitat in the Zapata Swamp in southern Cuba, has not been seen with certainty in nearly 20 years.
Wetlands are important for birds and for our well being too. Not only do they provide a home for wildlife, they also provide people with clean water, protection from floods and erosion, and opportunities for recreation and wildlife viewing.
Reddish Egret (dark morph) in Cuba by Antonio Rodriguez. This medium sized heron has 2 color morphs, light and dark. It inhabits coastal wetlands in the Bahamas and Greater Antilles islands. It is known for its energetic feeding behavior, running, jumping, flying and open wing dancing in pursuit of small fish in shallow water.
For years wetlands have been destroyed for development, damaged by pollution, or threatened by tourism, agriculture, cattle, industry, or sea level rise. Because wetlands are vital to birds and people, it’s important to know where they are, what birds are living in them, and what times of year they are being used.
BirdsCaribbean is answering these questions through the CWC, a program that aims to increase support for waterbird and wetland conservation by training a cadre of people to observe and record birds in wetlands across the Caribbean. Natural resource agency staff and citizen scientist volunteers help answer important questions while gaining an understanding and appreciation of migratory birds and the wetlands that they live in.
Since the beginning of the program in 2010, over 200 people from 21 countries have surveyed more than 700 areas! Each year, more and more people take part in the CWC. We have learned a lot of cool stuff over the last six years!
For example, several places stand out for their high numbers of birds. Sur de Los Palacios, Cuba is important to Wilson’s Plover throughout the fall, winter, and spring. This medium-sized bird is on the 2014 State of the Birds Watchlist, which lists species most in danger of extinction without significant conservation action. Knowing where they spend much of their time can lead to increased conservation for these sites in Cuba. Monte Cristi in northwestern Dominican Republic has been discovered as an incredibly important site for many shorebird species throughout the migration and winter season. Counts in the fall are especially high for Greater Yellowlegs (870 individuals), Lesser Yellowlegs (3,250 individuals) and Semipalmated Sandpiper (3,150 individuals), all being the highest overall counts for the species throughout the Caribbean!
White-cheeked Pintails in flight by Ernesto Reyes. Wetlands in the Caribbean are very important to migratory ducks like Blue-winged Teal and Lesser Scaup, and resident ducks, such as the White-cheeked Pintails, shown here.
Shorebirds like these only weigh a couple ounces; the Semipalmated Sandpiper weighs in at just a smidge more than a quarter, and flies thousands of miles from it’s breeding grounds in the Arctic to it’s wintering grounds in South America. Knowing where this bird stops along the way is important so conservationists can protect the places it needs to rest and feed for their long journey.
Another indicator of importance is the diversity—or how many different kinds of birds—are observed. Two locations in Guadeloupe (Pointe des Chateaux and Petite-Terre) and one in Cuba (Sur de Los Palacios) had over ten different shorebirds counted and seven other sites, located in Guadeloupe, Grenada, DR, Bahamas, Cuba, and Grenada recorded 9, 8 or 7 shorebird species. Some sites in the Caribbean like Sur de Los Palacios in Cuba and Monte Cristi in the Dominican Republic stand out for high numbers of all waterbirds, not just shorebirds. Of the 241 sites monitored in 2014 a total of 293 species were recorded!
What do all these numbers really mean? Knowing which birds are using what areas helps conservationists identify the most important sites to protect. Raising awareness, and showing the value of wetlands to local communities can lead to better care and protection of the wildlife using them. They become places to promote environmental education and bird and nature tourism. Enhancing key sites by installing boardwalks, viewing towers, and signs makes them attractive to visitors, which in turn increases their value for local people, livelihoods, and the economy.
During winter, some birds migrate, but many travel only short distances. Wilson’s Plover (female) at Mt Hartman wetland in Grenada by Greg Homel. This handsome shorebird is found in coastal areas, including sandy beaches, mudflats and mangroves. It is resident and breeds on many Caribbean islands. During winter, some birds migrate, but many travel only short distances.
While participation in the CWC has increased every year and we have already learned a great deal from the counts, there is still much work to be done! With over 7,000 islands and islets in the Caribbean, many important sites have not yet been surveyed. In addition, it’s important to continue surveying the same sites over the long term in order to document changes in waterbird numbers in relation to changing environmental conditions, for example, under climate change. Finally, we must continue to raise awareness about the importance and value of these sites to birds and people and promote protection and good management. Doing so will ensure that these critical wetlands are not lost forever; and birds and people will have a place to thrive.

The Cay Sal Bank remains remote and difficult to access. (Photo by Will Mackin)
From April 20 to July 15, 2010, the Deepwater Horizon tragedy spewed millions of barrels of oil and coated hundreds of thousands of square miles of the Gulf of Mexico with toxins. Naturalists and scientists who work in the Bahamas began preparing for the possibility that oil would round the tip of Florida and enter Bahamian waters. The Cay Sal Bank, one of the most remote and wild places in the Caribbean Region, was in harm’s way. This 5,000 square kilometer atoll is north of Cuba, Southeast of Florida, and Southwest of Andros, The Bahamas. It is a day-cruise from everywhere, lacks safe harbors, is exposed to rolling seas from all sides. We had very little data about the status of the birds, fisheries, coral reefs, seagrass beds, and small islands. It was known to hold thousands of breeding seabirds, but the most recent scientific visits were in 2000, and no one had ever actually surveyed the colonies. If the oil did coat the Bank, we would not even know what we had lost.

The Bahamas National Trust, The Nature Conservancy, The Royal Bahamian Defence Force, and numerous volunteers quickly organized three trips in May, June, and July of 2010 to document the wildlife on the bank and to determine whether oil was reaching the islands. As a volunteer on the first and third trips, I was astounded by the wilderness that we found. There were hundreds of uninhabited islands with little sign of humans except the occasional grave marker, ruined buildings from abandoned outposts, and plastic and aluminum flotsam from the Anthropocene. These islands are still dominated by birds, sea turtles, and anoles. A quick survey at Elbow Cay showed it was the largest Audubon’s Shearwater colony in the world, and a career’s worth of islands remained to explore and describe for posterity.
Thankfully, unusually strong easterly winds kept the oil in the Gulf of Mexico that year until the well was finally shut off. While tens of thousands of seabirds died from the effects of the spill, likely including individuals that commuted to the spill site from Cay Sal Bank, the oil never reached the Bank in amounts that we detected. We had dodged a bullet, but we don’t want to be caught without data again.

In 2012, we mounted an expedition just to study the birds of Cay Sal Bank. With support and funding from Biodiversity Research Institute (BRI), Defenders of Wildlife, the South Carolina Cooperative Fish and Wildlife Research Unit, BirdsCaribbean, and the National Fish and Wildlife Foundation, we explored the bank again from May 25-31, 2012. Bruce Purdy, expert birder and owner of Blackbeard’s Cruises, captained Sea Explorer, a 65’ sailboat. We recruited an all-star team of nineteen naturalists and seabird experts to spend a full week studying seabirds. Six ecotourists helped fund the trip by purchasing berths on the ship. Our team included well-known Caribbean Ornithologists Ann Haynes-Sutton, Lisa Sorenson, David Wingate, Sonny Bass, and David Lee. In addition, we had the developer of eBird software and knowledgeable birder, Jeff Gerbracht, Boston University Professor and Ornithologist Mike Sorenson and the fantastic mammologist Mary Kay Clark. Deb McKew, a marketing specialist from BRI helped promote and document the trip. Bahamian naturalists Predensa Moore and David Clare of the Bahamas National Trust rounded out our team of volunteer scientists. The ecotourists included Samantha Plencer, Caitlin Howard, Helge Wingate, Kathy Carpenter, David Pais, and Kathryn Sieving, a professor and fantastic ornithologist at the University of Florida in Gainesville who heard about the trip from our advertisement, called up, and signed up on the spot. Lisa Ferguson and myself, Will Mackin, organized the trip and lead the analysis of the data.
What we found was astounding. Every sandy beach on the bank was covered with crawls from nesting sea turtles. Tens of thousands of seabirds nested on Elbow Cay but thousands of others use the small cays we have yet to land on. The four biggest islands on the Bank have introduced rats and fewer seabirds, but we documented about 80 nesting pairs of Roseate Terns at Cotton Cay on the Southeast Corner of the Bank. And the waters of the bank team with life. Perhaps the most spectacular sight was a feeding frenzy including several thousand Brown Noddies and hundreds of Roseate Terns that stretched from the South End of the Elbow Cay to the eastern horizon. They were feeding on larval fish in shallow water with multiple species of jacks pushing bait to the surface.

On the second night of the trip, Lisa Ferguson, David Clare, Samantha Plencer, and I encountered a snake on the surface of Anguilla Cay, an 8-km long, thin island that hosts hundreds of Audubon’s Shearwaters and Bridled Terns. I had never seen a similar snake, so we brought it back to the boat. It turned out to be a Cuban Racer (Cubophis cantherigerus cantherigerus), the first specimen ever caught outside of Cuba. You can read the scientific highlights of the trip in our paper, including a full survey of the birds at Elbow Cay and explorations of wildlife at the other 4 large islands. A paper describing the results of these trips has just been published in the December issue of Waterbirds, the academic journal of the Waterbirds Society. Some people have argued that there is no such thing as wilderness anymore. Those people have never been to the Cay Sal Bank. It is true that no place on earth is untouched by man, but truly wild places do exist where humans are only visitors and wildlife runs the show. When we find one, something inside compels us to work to make sure it stays that way.
