2017 is the UN’s International Year of Sustainable Tourism for Development. So, what better topic to consider than that of Caribbean bird tourism for sustainable development and conservation?
Speakers at the BirdsCaribbean 21st International Conference in Topes de Collantes, Cuba (July 13 – 17) will be digging deeper into the eco-tourism field, and the potential of birding as a tourist attraction. Recent trends suggest that a more discerning and independent traveler in the Caribbean – as elsewhere in the world – has emerged, who is looking for a unique, authentic experience. Much greater sensitivity towards the culture and environment is a critical component of this – and of sustainable tourism in general.
So, although Caribbean tourism was built on the “sun, sea and sand” concept, it is evolving. In a highly competitive field some models need to be redesigned to cope with changing demands, says Assistant Professor of Marketing and Entrepreneurship at the University of Pittsburgh Skip Glenn. In Cuba, Glenn will discuss that critical “balance” that will build profit for entrepreneurs, while at the same time ensuring the preservation of natural resources and sustainable growth in communities.
Another recent trend is “sharing” via social media and online in general. Judy Karwacki of Small Planet Consulting in Vancouver, Canada will explore this growing tendency among travelers, many of whom are looking to “live like a local.” At the Cuba conference, Karwacki will provide practical marketing information and tips for birding tourism destinations.
One example of a bird tourism model is the Caribbean Birding Trail (CBT), developed by BirdsCaribbean, which aims to raise awareness (and enjoyment) of the remarkable diversity of birds in the region and to encourage their conservation. CBT’s aim is to work with partners on every island to offer training at the local level in bird-centered, sustainable tourism that includes experiencing local culture and heritage.
Holly Robertson and Lisa Sorenson will have plenty to update participants at the Cuba conference on the “latest” from the CBT, which has held interpretive guide trainings in Grenada, Jamaica, Dominican Republic and Bonaire to date. The U.S. Fish and Wildlife Service and the Marshall-Reynolds Foundation have funded supporting activities, including marketing products, an interpretive panel for Jamaica’s Cockpit Country, and improving trails and infrastructure in the Dominican Republic. The CBT is moving ahead!
There is much more to absorb and enjoy at the conference in Topes de Collantes. An informative and interactive Cuba Day will celebrate advances in the study and conservation of the island’s endemic, resident and migratory birds. A specific threat to bird populations on the island is the culture of caged birds; a workshop led by Gary Markowski of the Caribbean Conservation Trust will address this major concern and seek solutions.
The use of technology is something that no conservationist can ignore; the range of available tools expands almost daily. The use of drones for conservation is a fascinating topic, for example. Dr. David Bird, Professor Emeritus of Wildlife Biology at McGill University, will discuss the use of small unmanned aerial vehicle systems in monitoring populations of birds that are hard to access. Other technology-related topics will include how to use a GPS, mapping, and the value of eBird for conservation planning.
Would you like to write more fluently about birds, for a more general audience? The energetic Mark Yokoyama, co-founder of Les Fruits de Mer in St. Martin, will guide participants through a practical and motivating workshop on non-technical writing.
The conference schedule will also include stimulating talks and workshops on the Cornell Lab of Ornithology’s exciting BirdSleuth Caribbean program, which is making an impact in science education throughout the islands; a symposium on recent advances in seabird conservation in the Caribbean; and a roundtable discussion on long-term bird monitoring and banding in the region.
By the way – it’s not too late to register for the 21st International Conference in the beautiful Topes de Collantes Nature Reserve Park. For more details, please visit the Conference website.

Thousands of people throughout the region had fun experiences with birds and nature over the past month during the Caribbean Endemic Bird Festival. Dozens of festival events took place on different islands to celebrate the birds that live only here.
Activities were held for pre-school and primary students to adults and families. Bird talks were held on many islands to help people understand the unique birds that live only on specific islands or only in the region. Guided bird walks brought people of all ages out into nature to see these amazing birds firsthand. For many, it was their first chance to get an up-close view of birds through binoculars or a scope.
Other activities were as diverse as the region itself. In the Dominican Republic, The Peregrine Fund hosted Ridgway’s Hawk Day to celebrate the endangered Ridgway’s Hawk, that lives only on Hispaniola. In Trinidad, bird education was brought to the streets with bird education stand at a local market hosted by the Trinidad and Tobago Field Naturalist Club. In Puerto Rico, a special training workshop at the Centro Educativo del Corredor del Yaguazo gave teachers learning tools about birds to use in classes year-round. On St. Martin, festival attendees planted coconut trees with Environmental Protection in the Caribbean and painted bird feeders with Les Fruits de Mer.
Other groups that held events this year in Puerto Rico included Jobos Bay National Estuarine Research Reserve, Programa del Estuario de la Bahia de San Juan, Sociedad Ornitológica Puertorriqueña Inc., Centro Ambiental Santa Ana, Sociedad de Historia Natural de Puerto Rico, Proyecto: Reverdece Tu Comunidad – University of Puerto Rico Ponce Campus, and Universitarios Pro-Ambiente y Biodiversidad (UPABi) UPR-Ponce. In Dominica, the Forestry, Wildlife and Parks Division held events, as did Grupo Acción Ecológica in the Dominican Republic. Environmental Awareness Group hosted events in Antigua and Barbuda. Caribbean neighbors Fundación Científica Ara Macao in Venezuela and the Bermuda Audobon Society also hosted activities.
The Caribbean Endemic Bird Festival is one of the Caribbean’s only regional events about birds and nature. It is organized by BirdsCaribbean each spring, and dozens of non-profits, schools, parks and other organizations develop events in their communities.
Endemic birds—those that live only on one island or within a small range—are at special risk of extinction. The Caribbean is home to many endemic species, and many are already in danger.
In the pursuit of wildlife research, I’ve climbed cliffs, dodged black bears, ridden in tiny planes through turbulent mountain air, jumped into surging ocean waters, and hiked alone through remote wilderness. None of these activities have scared me as much as handling my first Roseate Tern chick, a delicate ball of fluff just hours from the egg, as I prepared to take a blood sample. Hands shaking, trying to ignore the shifting of my colleague, Daniel, as he moved to a better vantage point, I carefully stretched out the chick’s back leg, searching for the threadlike femoral vein. Anxious tern parents called and swooped above us in the early morning sky, and the chick peeped quietly in my hand. I angled the needle and, taking a deep breath, slid it gently in. My reward was a perfect bead of red blood. I transferred the blood into a vial of storage solution, handed Daniel the chick to return to the nest, and leaned back to savor the short moment of victory. One sample down, 29 to go.
This spring I started my first full field season researching Caribbean Roseate Terns. These gorgeous larids are an especially challenging seabird to study, as anyone who’s tried will be quick to tell you. Like many seabirds, Roseate Terns nest on small islands, which offer a relatively predator-free habitat to raise chicks. Unlike many seabirds, they move colony sites almost yearly, for reasons we haven’t yet been able to determine. In the Virgin Islands, which host ~50% of the Caribbean population, Roseate Terns have over 26 potential nesting cays that they choose from. That means that any research activities must first involve locating the birds, then figuring out a plan for that unique colony site. Caribbean Roseate Terns are also easily disturbed, and are prone to colony abandonment. Too much research activity in the colony could lower their reproductive success, which is the opposite goal of our efforts. For all these reasons, determining colony success through means such regular nest checks is not possible for this population, forcing us to get a little more creative.
Because Roseate Terns have such a large range, and aren’t too interested in country boundaries, effective conservation planning for this species requires collaborating across borders. I’ve teamed up with researchers from several organizations in the Caribbean for this project, chief among them Susan Zaluski from the British Virgin Islands’ Jost Van Dyke Preservation Society and Daniel Nellis from the US Virgin Islands Division of Fisheries and Wildlife. In addition to developing a standardized monitoring plan to use between the two territories, we’re working to answer some of the basic questions regarding Roseate Tern ecology in the region. Because nesting cays are so difficult to regularly access, we’re using motion-activated game cameras installed at nests to be our eyes in the colonies. This year, we have cameras in six active colonies. We’re hoping that the images from these cameras will help us better understand the role of predation in colonies, as well as incubation behavior and hatching success.
Roseate Terns are declining across the Caribbean, and we don’t know why. Are population declines due to low nest success at colony sites, or to low adult survival on wintering grounds? The breeding season is only part of a Roseate Tern’s year, and come August they will leave the Virgin Islands. Band returns have indicated that the birds travel to wintering grounds in South America, but we know very little about their non-breeding movements. Roseate Terns are smaller and lighter than other terns, and this has made following their movements using technology like satellite tags difficult. To answer some of the larger questions regarding population health and movement, we’re turning to another source: DNA. Caribbean Roseate Terns aren’t alone in North America—there is also a well-studied population in New England. These two populations are believed to share wintering grounds, but aren’t thought to interbreed. Such isolation is unusual for such far-flying seabirds, particularly as it’s thought that the migratory pathway of the Northeastern population takes them through the Caribbean. We’re partnering with agencies in the US to determine relatedness between Caribbean and Northeastern Roseate Terns through genetic analysis. Genetic information will give us a better idea of the population health of Caribbean Roseate Terns, and will provide some intriguing clues on who they’re mixing with on their wintering grounds, which might better help us understand where they’re going.
Which brings us back to that first morning of sampling. It’s best to get blood from chicks less than 3 days old. Younger chicks are easier to catch, and their skin is thinner and easier to pierce with a needle. They also seem to heal more quickly, with bleeding stopping within seconds—sometimes too quickly for me to get a full sample. All these sampling considerations make geneticist researchers like myself sound particularly, well, bloodthirsty, and have led to us being characterized as “vampires.” It’s a nickname I’ll proudly answer to, knowing as I do all the amazing secrets hidden in that remarkable substance. Unlike mammal blood, avian blood is nucleated, meaning that every blood cell contains copies of DNA. That DNA can tell us the history of an entire species and beyond, if only we can find exactly the right questions to ask and the right tools for answering them.
Figuring out the best timing for our DNA sampling required four separate boat excursions to locate the most accessible tern colony and estimate when the majority of eggs would hatch. After deciding that LeDuck island would be the best candidate for sampling, we returned early one morning to swim our gear onto the islands in waterproof coolers, then hiked through waist-length thorny brush to reach the terns. I set up my sampling station on a flat boulder, and Daniel and my visiting husband worked the colony, locating the tiny chicks and bringing them to me bundled up in hats, hands, pockets, and bandanas. We moved between colony sections to allow anxious tern parents to return to their nests, working as quickly as possible to minimize stress to the colony.
In all the haste, I still made sure to take a moment to breathe, look around, and enjoy the view. All that research planning, all those questions, came down to two short hours in the field and those 30 precious vials of blood. A year of collaborative effort went into my sitting on that boulder, first chick in hand, and I wanted to make sure that I took the time to appreciate it. After the Birds Caribbean conference in Cuba (hope to see you there!) I’ll be heading back to Louisiana to lock myself in the lab and get started on analyzing all this data. I’m so excited to see where these results take us, and look forward to sharing my findings with you all in the future!
Paige Byerly is a PhD student at the University of Louisiana at Lafayette. Her research investigating genetic diversity among Roseate Terns in the Virgin Islands is supported by a grant from the BirdsCaribbean David S. Lee Fund and a research fellowship from the National Science Foundation. The Caribbean Roseate Tern, is a threatened metapopulation of Sterna dougallii dougallii, and thought to be declining across its range. Her research will help conservationists better understand the migratory ecology and population vulnerability of Roseate Terns.
The journal British Birds is keen to highlight Important Bird Areas (IBAs) in the UK Overseas Territories (UKOT) and Crown Dependencies in the Caribbean. Developed by BirdLife International, the IBA program strives to identify, document and protect all places on earth of greatest significance for the conservation of birds. Our members may already know how important IBAs are in the Caribbean – especially for the protection of restricted-range species and endemics. It is fantastic to see these unique areas receiving wider exposure.
Four UKOTs in the Caribbean region have already been featured in the journal: Bermuda, Montserrat, The Cayman Islands, and Anguilla. Each one provides a thorough account of bird life in the territory with over 10,000 words, numerous photos and maps, making them an excellent addition to the region’s ornithological literature. Well done to all the authors. We have included the abstracts of the four reports here; to read the full articles you can subscribe to British Birds or you can buy an individual issue at their website.
Important Bird Areas: Bermuda
Published on 08 March 2017 Andrew Dobson and Jeremy Madeiros
Bermuda is a UK Overseas Territory in the western North Atlantic and was uninhabited before being settled by the British over 400 years ago. It is one of the most isolated inhabited islands in the world. Despite its remoteness and its suburban landscape, it has a remarkable avian richness and history. The rediscovery of the breeding grounds of the Cahow, or Bermuda Petrel Pterodroma cahow, in 1951 made international news in an age without social media. The continuing success of the Cahow recovery programme provides hope for similar projects elsewhere. There is a globally significant population of White-tailed Tropicbirds Phaethon lepturus and there are proposals to confer endemic subspecies status on the locally breeding Common Tern Sterna hirundo. Current threats to Bermuda’s biodiversity include climate change, the increasing frequency and intensity of tropical storms, and invasive species.
Important Bird Areas: Montserrat
Published on 16 February 2015 Steffen Oppel, Gerard Gray, James Daley, Stephen Mendes, Calvin Fenton, Gemma Galbraith, Shawn Daniel and James Millett
Montserrat is a small jewel of an island in the eastern Caribbean. After a major volcanic eruption in 1995, two-thirds of the island became uninhabitable, and today Montserrat is off the beaten track for most tourists. The island is easily accessible, however, and a range of habitats support a variety of interesting native biodiversity. Three hill ranges exist on the island, the southernmost being an active volcano and mostly devoid of vegetation. The Centre Hills, an area of semi-natural forest, is home to endemic species such as the Montserrat Oriole Icterus oberi, the Montserrat Galliwasp Diploglossus montisserrati (a skink), and the ‘Mountain Chicken’ Leptodactylus fallax (a frog). Besides the Centre Hills forest, there are dry scrublands in the northern hill range, coastal cliffs, and some unspoilt beaches with scenic reefs suitable for snorkelling and diving. The island’s habitats suffer from the effects of multiple non-native species such as feral pigs, goats, cattle, rats and cats. Efforts to control these are under way, and the Centre Hills forest is protected. Protecting the forest on Montserrat is the most critical target both for native biodiversity and for water supply on the island.
The Cayman Islands, in the western Caribbean, are a UK Overseas Territory. Three main islands support a wide range of birds, with 17 endemic races of breeding landbird. The Grand Cayman Thrush Turdus ravidus, currently treated as the only endemic bird species, was last seen in 1938. However, taxonomic research may mean that ‘Taylor’s Bullfinch’ Melanopyrrha (nigra) taylori, which occurs only on Grand Cayman, is treated as full species. There are many challenges of managing a conservation strategy on small islands such as these. The currently rapid human population growth (with a variety of associated development pressures), and the prospect of increased number and severity of tropical storms, are two of the most important threats to the biodiversity of these islands. Strategies to address these issues by the National Trust and National Conservation Council are discussed.
Important Bird Areas: Anguilla
Published on 04 August 2015 Steve Holliday, Karim Hodge, Farah Mukhida, Clarissa Lloyd, James Millett and Louise Soanes
Anguilla is a UK Overseas Territory, the northernmost of the island groups in the Lesser Antilles, in the eastern Caribbean. It has been long known for its seabirds; 16 species currently breed, with Red-billed Tropicbird Phaethon aethereus, Brown Booby Sula leucogaster and Sooty Tern Onychoprion fuscatus occurring in globally important numbers. There are 16 Important Bird and Biodiversity Areas (IBAs), including five of the islands holding the main seabird colonies. The mainland IBAs are identified for populations of breeding seabirds, including Least Terns Sternula antillarum, and/or five restricted-range terrestrial species confined to the Lesser Antilles Endemic Bird Area (EBA). The Dog Island IBA is one of the most important seabird colonies in the Caribbean. Considerable economic growth in recent decades, especially from increased tourism, presents challenges to ensure that new development is sustainable, helping to maintain the rich biodiversity and natural resources upon which the growth is founded.
Birds are inspiring creatures. Their amazing migrations and behaviors capture our imagination, and their global presence lets us appreciate them wherever we are in the world. The power that birds have to bring people together across cultures, languages, and international borders is truly exceptional. Global Big Day is the realization of the magic of birds—a single day where the birding world unites in a shared pursuit, seeking to answer the simple question: how many birds can be seen in one day?
On 13 May 2017, almost 20,000 birders from 150 countries around the world joined together as a global team, contributing more than 50,000 checklists containing 6,564 species—more than 60% of the world’s birds. This is a new record for the number of bird species reported in a single day!
With one of the highest endemic species ratios, the avifauna of the West Indies is important to have represented on Global Big Day. In the eBird Caribbean region*, 280 species were seen – Check out the list of species reported. Ninety-two participants submitted 334 checklists. These totals are lower than last year’s Global Big Day, but perhaps some people still have not entered their data. Note that it is not too late – your checklists will still be counted!
Birders in Trinidad and Tobago sighted the most number of species—164 in the region. The Bahamas and Puerto Rico were in second and third place with 129 and 95 species observed, respectively, and there was participation through many of the islands—21 countries/islands submitted checklists (see how your country compared to the rest of the region and world here). Thanks to all of you that helped spread the word and participated!
Global Big Day is a celebration of birds. By bringing people together, Global Big Day showcases the great birds from each region—helping bring awareness to birding and conservation regionally and globally. Cornell Lab of Ornithology reports that this year (as in previous Global Big Days), the friendly competition in South America continued to evolve as an inspiring story, with four countries topping 1,000 for the single-day tally: Brazil, Ecuador, Peru, and Colombia. In past years Brazil and Peru had always vied for the #1 slot for species totals, and in 2017 there is a new champion: Colombia. Next year, let’s set a goal for the West Indies to see the most endemics in a region, it can be done!
Thanks again to everyone who participated and made this Global Big Day successful. We hope you had a great time and will continue to participate in eBird Caribbean and future Global Big Days. Of course, eBird Caribbean doesn’t only exist on one day of the year. Global Big Day is just one of 365 opportunities/year to be a part of a global network of birdwatchers, researchers, and conservationists working together with a shared passion for birds. Any bird that you see, anywhere, at any time, can become a part of this global resource—helping your fellow birdwatchers as well as the birds that we all care about. So take a look at eBird Mobile, or how to find birds near you. Go out, explore, have fun, and let all of us know what you saw. Your sightings can help change the world. We’ll see you out there.
*The countries comprising the eBird Caribbean portal consist of the West Indies plus Trinidad and Tobago, Aruba, Bonaire, Curaçao, and Bermuda.

The BirdsCaribbean International Conferences, which take place every two years, are always enriching experiences for scientists, ornithologists, conservationists, students, teachers and bird enthusiasts from across the Caribbean. This year’s conference, which will take place in the beautiful Topes de Collantes region of southern Cuba from 13-17 July, 2017, promises to be no exception.
This year’s theme is “Celebrating Caribbean Diversity.” The organizers aim to make the 2017 meeting even more exciting than the 2015 meeting in Jamaica, which was attended by over 260 delegates. The planned conference program offers a taste of what’s in store. Distinguished keynote speakers will discuss a range of topics of significance to the region’s ecology and biodiversity, including conservation challenges, technological advances, civil society outreach and the latest research and educational programs.
Headlining the all-star line-up of international keynote speakers is award-winning ornithologist Professor Lourdes Mugica Valdés of the University of Havana. Dr. Mugica will discuss her three decades of work on Cuba’s aquatic birds and their wetland habitats conducted with the University’s Bird Ecology Group.
Dr. Hiram González will present the work of Cuba’s Institute of Ecology and Systematics group on bird migration. Cuba is an incredibly important stopover and wintering site for migratory birds and the Cuban government has set up an impressive network of protected areas to conserve biodiversity, including Cuba’s 26 endemic bird species. As more and more tourists and birders flock to Cuba, however, there is more to be done with international partners to ensure that as many important habitats as possible are not destroyed for development.
Dr. Robert Ricklefs, Ornithologist and Ecologist and Curators’ Professor of Biology at the University of Missouri, St. Louis, will give a talk focusing on the conference theme of diversity, highlighting how the Caribbean is a global hotspot for birds. He will provide an overview of the evolutionary history of Caribbean birds, island biogeography, and host-parasite evolution (i.e., birds and malaria), using his own research in the Caribbean as well as others, to illustrate how populations expand(which may lead to the formation of new species), and decline over time. He will show how understanding genetic differences between avian populations also informs us about evolutionary uniqueness of island birds and can help us to develop conservation programs.
Cornell University’s Professor of Ecology and Evolutionary Biology, Dr. David W. Winkler, will talk about his comparative research on swallows in the genus Tachycineta with partners throughout the Western Hemisphere. He will also share the work he is doing with engineers to develop new technologies for tracking bids and discovering more about their lives, including very lightweight, long-lasting radio tags with ever-expanding capabilities.
Conservation issues are always high on the agenda, and Dr. Nicasio Viña Dávila, Technical Coordinator of the Caribbean Biological Corridor of the United Nations Environment Programme, will present his perspective on those burning issues directly impacting conservation in the Caribbean.
Dominican Republic-based consultant Ms. Leida Buglass, who is Secretary for the International Union for the Conservation of Nature (IUCN) Caribbean Regional Committee, will talk about how important it is to engage with partners in civil society to advance bird and habitat conservation, including case studies and lessons learned from many years of community work.
And there’s more. Informative sessions and training workshops include promoting sustainable bird tourism and updates on the Caribbean Birding Trail, bird education, the use of media to promote conservation issues, the state of Caribbean forest endemic birds, ecology of migrants, and many more.
There will also be a special Cuba Day, where local ornithologists will share the work they are doing to study and conserve the island’s rich bird life and habitats. There is much to learn and enjoy!

Maya Wilson is a graduate student at Virginia Tech researching the ecology and life history of the Bahama Swallow, an endangered species endemic to the Bahamas. She is one of the dedicated young scholars who was awarded the BirdsCaribbean David S. Lee Fund Grant and her work is critical to understanding the Bahama Swallow and informing conservation strategies. Here, she discusses her research and describes her exciting field experiences with this unique species.
As we exit the truck, I hear a series of aggressive clicks and feel a rush of air as a wing brushes only a couple inches from my head.
When the Bahama Swallows began breeding, we started watching this particular area intensely, suspecting that the large, still-standing dead pine tree (i.e. pine snag) only a few paces from the old logging road would be a choice spot for a pair of swallows to make their nest. Sure enough, a couple weeks ago we found three white eggs. We are now scheduled to come back to see if those three eggs have hatched, and the parents are obviously well aware of that.
The bird that dove at my head joins its mate on a small exposed branch in a nearby tree and they chatter to each other, seeming to make a plan, before taking off again to resume their “attack.” It is hard to resist the urge to duck as I watch the male turn toward me and dive again, this time straight at my face. However, just like every other time, he changes direction at the last possible second — a signature move of a swallow. In reality, these small (~15 g) birds can’t hurt us.
The three of us walk to the back of the truck and begin to assemble the “peeper” camera so that we can take a closer look. Using several specialized pieces of hardware, we attach the camera to a large extension pole. I hoist the apparatus onto my shoulder to keep it steady, carefully climb over the pile of loose limestone along the road, and circle around to the other side of the snag. The nest is inside a hole (i.e. cavity) about 31 feet (9.4 meters) up, making this one of the highest nests we have studied, and therefore one of the hardest to observe.
I turn the camera on, and Mel confirms that it is wirelessly sending images to the monitor she is holding. I begin hoisting the pole upward, locking each section into place. Finally, the camera is near the correct height, and Shannan, who is standing back so that she has a good vantage point, guides me until it slips into the nesting cavity.
“Two chicks!” Mel shouts, and then, “wait, the last egg is hatching!” There is a bustle of activity as we all try to look at the small screen to see what is happening in the nest. Sure enough, the last egg has a crack down the middle, and a nestling is trying to fight its way out to join its two siblings in the nest.
We record a short video and then I bring the camera down. We all head back to the truck, disassemble the camera, and pile back in while the adult swallows take turns making sure that their newly hatched nestlings are okay. We have to try our hardest to disturb the nest as little as possible, so we decide to leave this family alone for a few days.
The memory of watching a Bahama Swallow nestling hatch during the summer of 2016 will stick with me for the rest of my life. I am back on Great Abaco Island again in 2017, and for the third field season in a row our team will be made up of three women in their twenties. Dressed in worn-out field clothes and carrying our peeper camera and other equipment through the forest, we certainly get our fair share of confused stares. But we spend several months of the year in the northern Bahamas for a reason. Great Abaco, Grand Bahama, Andros and New Providence are the only islands within the more than 700 islands that make up the Bahama Archipelago that contain large areas of the native Caribbean pine (Pinus caribaeabahamensis). This is why these three islands have rightfully earned the nickname, “pine islands.”
These pine forests are home to many birds, including five of the six Bahamian endemic species. One of these endemic species is the endangered Bahama Swallow (Tachycineta cyaneoviridis), which has only ever been found to breed on the pine islands. This bird, along with many other Caribbean endemics, is severely understudied.
My graduate research focuses on three main areas, with the overarching goal of providing information that is relevant to the species’ conservation to my main collaborator, the Bahamas National Trust, as well as other local organizations.
(1) How many Bahama Swallows are left, how are they spread across the pine islands, and do birds on the different islands breed with each another? There have only been a few official estimates of Bahama Swallow population levels over the past 30 years, and they indicate a rather dramatic decline. The IUCN Red List estimates a current population of 1500-4000 individuals. Using multiple survey techniques, I hope to provide a more precise estimate that will shed some light on overall species abundance and whether Bahama Swallows favor certain habitats or islands in general. Using genetic information, we can determine whether the species has become separated into smaller, isolated populations, which would have significant implications for the survival of the Bahama Swallow and subsequent conservation management plans.
(2) When and where do Bahama Swallows breed, and how successful are each of their nesting attempts? Bahama Swallows are obligate secondary cavity-nesters, meaning that they will only build nests inside a cavity; however, they do not have the ability to create that cavity themselves. Rather, they rely on natural processes or other excavating species to create cavities for them. In 1995, Allen (1996) conducted a study that revealed important information about Bahama Swallow breeding biology and behavior. The swallows breed between April and July, laying an average of three eggs in abandoned woodpecker cavities in pine snags and various other cavities. By locating swallow nests in all cavity types, and then monitoring those that we can safely access, we hope to provide additional information on the determinants and limitations to the breeding biology of the species.
(3) Is breeding habitat limited? How do Bahama Swallows interact with other cavity-nesting species in the same habitat? Almost all of the forest on the pine islands is secondary growth, the result of extensive logging that took place from 1905-1969. It still is not clear what effects the logging and subsequent disturbances (e.g., fire and hurricanes) have had on the structure of the pine forest or the surrounding habitats, and on the species that inhabit them. The Hairy Woodpecker (Leuconotopicus villosus) is present on all of the pine islands, and is closely associated with the pine forest, although it can be found in other habitats. In The Bahamas, the larger West Indian Woodpecker (Melanerpes superciliaris) is mostly limited to Great Abaco, where it is mostly associated with dry broadleaf “coppice” and human habitation. The swallows and other secondary cavity-nesters rely on these woodpeckers to create cavities for them. However, the availability of cavities and the competition for those cavities may vary between habitats (e.g., pine forest vs. towns). We can look at these interactions by assessing the availability of nesting resources and documenting nests of all cavity-nesting species.
My research has come a long way since it began in 2014, though there is still much to accomplish. My team and I continue to unravel the ecology and biology behind the pine islands and their Bahama Swallows, and are currently getting our 2017 field season underway. I look forward to keeping the BirdsCaribbean community updated as the project progresses and am excited to meet more of you at the Cuba Conference this July.
Dan Stonko joined Dr. Kevin Omland’s research group studying the Bahama Oriole as an undergraduate at the University of Maryland, Baltimore County. With the research team, he traveled to Andros in the Bahamas to search for the nesting Bahama Oriole and gained invaluable field experience while making memories of a lifetime (check out his recent blog article). Here, Dan summarizes his perspective of science, education and mentoring as learned through his undergraduate experiences.
As an undergraduate, I have been incredibly lucky with the opportunities I’ve received. Taking on undergraduate students into your lab can be risky in itself for multiple reasons – we are usually inexperienced, require time and effort to train, and usually can’t contribute nearly as much as a higher-level student/employee. For these very reasons, I have come to be evermore grateful for getting the kinds of opportunities as amazing and impactful as I’ve shared in my previous blog post. Whenever anyone asks me about our lab’s work, I start off by discussing the science and research. Before long, I tend to catch myself getting into the unexpected and memorable lessons I’ve learned. So here are just a few of those lessons:
1. The most impactful learning can happen outside of the classroom
Okay, this might sound cliché. But when I started college, I felt certain that most of my time in college would be spent either in class or studying. I then reasoned that most of my learning would therefore happen in class or while studying.
I graduate in two months and can definitely confirm that this is how I spend most of my time. Yes, as a biochemistry major I have gained much of the central scientific knowledge through classes. However, the science I study has come to life through my research. I’ve applied my knowledge to real-world situations, designed experimental procedures, built relationships with mentors, collaborated with peers, and worked in the field. These lessons and experiences will be with me forever, and they’re the kinds of things you can’t get by simply sitting in class or reading a textbook.
2. Science is a verb
Whether doing field research in a pine forest, looking through a microscope or telescope, or mixing chemicals in a beaker – I have come to see science, in its purest form, as the pursuit of knowledge. Not a noun, but a verb. It is the act of careful observation, meticulous investigation, and ceaseless questioning of the things around us. If the pieces fit together just right, our curiosity can be rewarded with an expanded understanding of our world.
3. Modern discoveries in science are made possible by our predecessors
Isaac Newton once wrote that, “If I have seen further it is by standing on the shoulders of giants.” Before I got involved with research, that adage sometimes crossed my mind; often it would do so while reading or hearing about some unimaginably complex discovery that undoubtedly depended on contributions from many people. This thought always gave me a fundamental admiration for the explorers and scientists who came before us. As a researcher, I’ve gained a new and deeper understanding of Newton’s words.
Going into our first trip, most of what was known about the Bahama Oriole came from earlier research by Dr. Melissa Price. Her work provided the most recent population estimates and gave thorough information on the reproductive ecology of the species. Whether I was in the field collecting data or in lab drafting the manuscript to share our findings – I knew that her work (and that of countless others) influenced our work. It’s a humbling reminder for a scientist to keep in mind: with every day that we work and every discovery that we make, our progress is possible because we stand on the shoulders of the giants who mentor us and came before us to provide our foundation.
4. Observation is the true driver of science
Some areas of popularized science today seem to reinforce (what I believe to be) a subtle yet significant misconception, which presumes that questions are at the bedrock of any scientific endeavor. However, I have found observations are the truest foundation. Countless scientific advances throughout history didn’t arise by seeking answers to specific questions. Even when questions have led to advances, initial observations were always there to lead to those questions in the first place. In other words, we first make observations about our world, which then allow us ask questions such as: What? Why? When? How? It all may seem like semantics, but I believe that grasping this subtle distinction instills a sense of deserved respect for observation as the most critical scientific tool for discovery.
Some of our research on this first trip was oriented towards specific questions or goals, such as the distance sampling surveys that we used to estimate population size. The majority of our efforts, however, occurred without particular goals and depended simply on observation (e.g. catching and banding orioles, recording observations on bird behavior, and finding nests). At first, this idea of working without a particular goal in mind may seem counterintuitive. Nevertheless, the work proved invaluable as it led to us finding orioles nesting in the pine forests. This trip serves as reminder that simply listening, watching, and being present to make observations can lead to unexpected discovery.

How many birds can a world of birders find in one day? Hopefully, you will join us to find out on May 13th — Global Big Day. This is the single biggest day for eBird and we’re inviting everyone to spend some time counting and enjoying Caribbean birds to help support global conservation efforts (and to have some fun in the process). Last year was a huge success that broke records around the world and across the Caribbean. The question is: Can we do it again?
More than one hundred Caribbean birders participated in last year’s Global Big Day, setting a new Global Big Day record for the Caribbean itself- 428 species! Thank you for making this possible. Your contributions to the past two Global Big Days have set back-to-back world records for the most bird species seen in a single day. Last year’s Global Big Day featured more than 60% of the world’s bird species in a single day (6,299!), with sightings coming in from more than 17,500 eBirders spread across 154 countries.
Want to be a part of the fun this year? If you need an excuse to go enjoy birds on a lovely weekend day in May, we’ve got you covered. The West Indies, with it’s 175 endemic bird species, along with it’s near endemics and endemic subspecies, will be key in gathering a snapshot of bird distribution around the globe.
If you’re looking to get started preparing for this year’s Global Big Day, here are four quick ways to have the most fun:
“Scout” your birding spots for May 13. Finding where the birds are ahead of time makes the big day birding more fun, and also gives you more chances to be out enjoying birds. Perfect. Learn how to use eBird to find birds.
Use eBird Mobile. This free data-entry app makes it so you don’t have to enter your sightings at the end of the day, and tools like Quick Entry mean you have less time with your face in a notebook. Get eBird Mobile here.
Get a friend involved. Perhaps this is a good birding buddy, or someone who has never been birding before. Make it a friendly competition, or join forces as a Global Big Day team, and put your marker on the global participation map. Share on social media using #eBird_GBD. Check out the Facebook event.
Participating in Global Big Day is a great way to celebrate the Caribbean Endemic Bird Festival, ongoing now! Make this a part of your celebration and organize a birding outing with family, friends or your community.
No matter what you do—have a great time, enjoy the birds around you, and let us know what you find! We’re excited to see what we can achieve together on Global Big Day.
And don’t forget to enter your Caribbean bird counts into eBird Caribbean – our own portal. All the data goes to the same place but we have some of our own protocols (Step 2 of data submission), for example, counts conducted at wetlands, ponds, mud flats and beaches can be entered as Caribbean Waterbird Census counts.
