#BarbudaStrong—Guadeloupe Bird Survey Team Plays Good Neighbors following Hurricane Irma

All of us at BirdsCaribbean followed the passing of Hurricane Irma with terror, for the people of Barbuda, and also for its birds. Such is the strength of our community that BirdsCaribbean members from nearby Guadeloupe – Anthony Levesque, Frantz Delcroix, and Eric Delcroix – all members of the organization AMAZONA, offered their help in surveying their neighboring island, alongside a team of ornithologists from the United States, Saint Lucia, and Antigua. Here’s Frantz’s story of their 10-hour expedition to Barbuda.

From Guadeloupe to Barbuda: Our Eventful Journey

The start of our day was scheduled for Sunday, October 15, 2017, around 6:30am. Our transport was a small Piper PA28 airplane, with a capacity of 4 people (the pilot and three passengers). The plane was sturdy enough to transport us, our field equipment, a cooler, and our boots! Despite bad weather for several days—an active tropical wave passing by Guadeloupe and Antigua and Barbuda—our pilot assured us that we could travel. Just before leaving, however, our pilot learned that due to cloud cover, the airport in Antigua (where we had to land first) was closed to all VFR (visual flight rules) flights, and was accepting only flights that can fly under IFR (instrument flight rules). Fortunately, we chose the right pilot; his plane was equipped and certified for this kind of flight!

We took off at 6:50am, landing in Antigua around 8:00am. It was a longer flight than we had anticipated, because we were flying under IFR. After passing through immigration, we went to the control tower to validate the flight plan to Barbuda. As we suspected, we had trouble with the fact that we did not have written authorization to travel to the island. Luckily, with the help of the Department of Environment in Antigua, we had taken the precaution of obtaining the necessary contact information for the authority, Major Michael, in Antigua. After a short discussion, the agent agreed to call the Major, and so was able to validate our flight plan to Barbuda. With a sigh of relief, we took off from Antigua around 9:00am and arrived in Barbuda twenty minutes later.

On Barbuda: The Birds’ Message of Hope

Upon arrival we made our first survey: a few Barn Swallows and a Bank Swallow circled above us and an American Golden Plover wandered around the airport parking lot. We were then greeted by an agent from the airfield, who kindly took us to the port where the rest of the team has just arrived by boat. There we met Jeff Gerbracht (Cornell Lab of Ornithology, USA), Frank Rivera (US Fish and Wildlife Service, USA), Lenn Isidore (Flora and Fauna International, St. Lucia), and others and went to the house that served as home base during our trip, as we did some birding around the neighborhood. Jeff, Frank, and Lenn planned to be in Barbuda for a full week to do an intensive survey of the Barbuda Warbler population (stay tuned for their story!). Our assignment was to visit Codrington Lagoon and carry out a survey of the Magnificent Frigatebirds, to see how the population and sanctuary was recovering six weeks after Hurricane Irma hit. We departed at 11:15am for Codrington Lagoon with our boat captain Kelly – and our pilot (who wanted to discover the avifauna of Barbuda with us!)

We arrived at the colony at 11:30am and were delighted to see hundreds of frigatebirds in flight, the bare and brown bushes adorned with bright red gular pouches. Within a 4.5 hectare (11.12 acre) area, we estimated 1,710 Magnificent Frigatebirds and 17 Brown Boobies. In a count of seven bushes of 279 frigatebirds, 83 females (30%) and 196 males (70%) were counted. Amazingly, 90% of the females were on nests and some of the birds were observed courting and mating, even males carrying nest materials.

We returned to home base around 12:30pm for a lunch break and then went back to the field. Having no vehicle available, we decided to visit a nearby pond we had observed on the Barbuda map, to search for West Indian Whistling-Ducks and other waterbirds. Along the way, we made several surveys of the species present. In a scrubby area near town, we spotted our first Barbuda Warblers eating caterpillars! The warblers were active and responded readily to our “pishing.”

Around the pond, we recorded two Lesser Antillean Flycatchers, two Long-billed Dowitchers, a Stilt Sandpiper, some Semipalmated Sandpipers, a Solitary Sandpiper, and a Scaly-breasted Thrasher. Unfortunately, no West Indian Whistling-Ducks were seen.

We continued our surveys until around 2:45pm before returning to home base to pick up our belongings and walk to the airfield for our 3:45pm takeoff. Skirting some clouds along the way, we arrived home in Guadeloupe at 4:20pm with a list of 36 surveyed species in hand.

Our Hearts are with the People of Barbuda

Although we were there to conduct a birding survey, our hearts ached when we saw all the damage on Barbuda. Such utter desolation! We felt anguish and sadness for the people of Barbuda, who lost everything in this category 5 hurricane and are now living in Antigua awaiting word on when they can return home and rebuild. Witnessing the power of nature—its ability to inflict such damage, but also how it can quickly rebound—was an extraordinary experience.

Before the hurricane, the 4,000–5,000-strong frigatebird colony had chicks in the nest. Surveys just after the hurricane found no surviving chicks and only around 300 birds. Now, one and a half months later, there are more than 1,700 frigatebirds starting a new breeding period with almost all of the females nesting! Even the mangroves that suffered from salt burn and had lost all their leaves were bouncing back, beginning to sprout new leaves.

So, we did not leave without hope. Nature is resilient! It can destroy almost everything, and yet incredibly allow a bird that weighs only ten grams to survive!

We thank all of our partners and friends from Antigua and Barbuda and BirdsCaribbean for trusting us and for providing funding and support for our survey, despite the challenges and the relatively short time we had to mobilize. We extend a special thanks to Natalya Lawrence of the Environmental Awareness Group (EAG) in Antigua and Lisa Sorenson of BirdsCaribbean

Frantz Delcroix is the President of AMAZONA, a bird conservation organization in Guadeloupe. She is an avid birder, photographer and conservationist. Thanks to all who donated to our Hurricane Relief Fund which provided funding for this survey. Thanks also to support from the Environmental Awareness Group and Dept of Environment in Antigua, and Fauna and Flora International.

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

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

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

Yellow-crowned:

Orange-winged:

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

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

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

Vocalizations: an unsung hero

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

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

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

How can you help parrots in the wild?

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

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

 

Scarlet Ibis: A National Symbol Under Siege

Flying low over the water and glowing brilliant red in the light of the setting sun, thousands of Scarlet Ibis quietly assemble at their roosting site. While the Tricolored Herons and bright white Snowy Egrets disappear into the cover of the mangroves, the Scarlet Ibis remain perched on top, dotting the dark green with intense bursts of red. To witness this spectacular ritual— a daily occurrence in the Caroni Swamp in Trinidad—is to experience one of the most extraordinary events in the natural world.

The Scarlet Ibis (Eudocimus ruber) is both culturally and economically important to the twin island nation of Trinidad and Tobago. When the country gained independence in 1962, it was fitting to declare the Scarlet Ibis as the national bird and it is featured prominently on the nation’s coat of arms and one dollar bill. Since at least the early 1970s, bird-watching ecotours in Caroni Swamp were generating over $1 million TTD annually. Today, the swamp and the ibis are internationally known as a “must-see” natural treasure, and the ecotourism industry continues to support the livelihoods of many Trinidadians.

Unfortunately, the Scarlet Ibis is also coveted for another reason: its meat. In an interview last month, the Chief Game Warden acknowledged that the bird is a black market delicacy illegally served at elite parties, driving the motivation for poaching. It has been speculated that eating the national bird is a status symbol. In 2013, a man with 18 ibis carcasses was sentenced to 18 months in prison (though he was allowed to serve them concurrently). And just this summer, three people were arrested in the possession of ibis carcasses and blasted on social media by Agriculture, Lands and Fisheries Minister Clarence Rambharat. His comments were widely shared and sparked dozens of newspaper articles, with the outraged public calling for action.

The national bird has a long history of persecution and is incredibly sensitive to disturbance. As early as the 1860s, colonial records warn that “a fierce war has been made on this bird…already it comes in fewer numbers and soon it will be very rare.” Other reports from the early 1930s and 1950s acknowledge that the Scarlet Ibis are “shot ruthlessly for food or so-called sport” and that they are very wary as a consequence. Richard ffrench, the neotropical ornithologist based in Trinidad, noted that in the beginning of the 20th century, hunting prevented the Scarlet Ibis from breeding on the island until 1953.

Currently, the fine for hunting or possessing the Scarlet Ibis is just $1,000 TTD (~$150 USD) or three months in prison. But due to the vast expanse of the Caroni Swamp and limited manpower, enforcement is difficult. In 2010, six individuals were fined $750 TT each for poaching offences that took place in 2007. Surprisingly, this marked the first time in the country’s history that someone was convicted of hunting the Scarlet Ibis.

Minister Rambharat has petitioned the Environmental Management Authority (EMA) to initiate the process to change the designation of the Scarlet Ibis to an Environmentally Sensitive Species (ESS). Under this protected status, poachers could receive a maximum of a $100,000 TTD fine or up to two years imprisonment. An ESS status would also facilitate interagency and joint patrols in Caroni Swamp, increasing warden and police presence. In addition, the EMA is exploring changing the status of the Caroni Swamp to an Environmentally Sensitive Area (ESA). The swamp is already designated a Ramsar site (1993) and a Prohibited Area under the Forests Acts.

Even young Trinidadians are raising awareness about the poaching of the national bird. In August, 45 performers aged 9-17 years old from the Moko Jumbie Cultural Camp dressed as Scarlet Ibis and marched in the capital’s Queen’s Park Savannah. This Caribbean stilt-walking art form is common during carnival season, and the camp’s mission is to preserve this custom and create cultural legacies by engaging children. It was a fantastic idea to combine this unique cultural heritage with the natural heritage of the Scarlet Ibis! Click here to see the video.

What you can do to help:

  • Please spread the word that the EMA is requesting information (including observations), research, or data about the Scarlet Ibis to assist with changing its status to an ESS. Information can be submitted here.
  • The mandatory 30-day public comment period for the change in status to ESS will be announced shortly. Please check the EMA website or Facebook page for updates and send a letter in support of this change in protected status.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Caribbean’s Birds Featured in British Birds Journal

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

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.

Important Bird Areas: The Cayman Islands

Published on 10 May 2016

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.

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.

 

 

Bahama Swallows in the “Pine Islands”—Report from the Field

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 caribaea bahamensis). 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.

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

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

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

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

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

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

2. Science is a verb

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

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

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

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

4. Observation is the true driver of science 

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

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

Environmental Educators Become BirdSleuths in the Bahamas

In the Caribbean and around the world, teachers and other educators are looking for new ways to engage students with the natural environment, inspire an interest in science and math and help youth learn to work together as a team. Some environmental educators believe birds may be the perfect focal point for accomplishing these goals, and the BirdSleuth Caribbean program was developed. During an intensive three-day training session in the Bahamas, Caribbean educators learned the program and are now poised to spread the program throughout the region.

The Retreat is a small national park nestled amongst the hustle and bustle of Nassau, Bahamas. Inside The Retreat, two dozen educators and conservationists from different islands throughout the Caribbean gathered October 15 to 17, 2014 to learn the BirdSleuth Caribbean curriculum. After their training, they returned to their islands ready to share this program with teachers and students.

BirdSleuth Caribbean is a program designed to teach youth how to study, appreciate and conserve Caribbean birds. It is part of a larger BirdSleuth program developed by the Cornell Lab of Ornithology. The original, US-based BirdSleuth program was adapted specifically for the Caribbean and its birds. At this workshop, each attendee was trained in the program and return with a full kit of supplies to implement the program. Over the coming months and years, workshops will be held throughout the Caribbean to train local teachers this program so they can share these activities with their classes.

The BirdSleuth curriculum includes many fun, hands-on activities, like creating a bird journal, learning to use binoculars and doing bird counts that can be entered into the citizen science website eBird Caribbean and used in actual scientific research. One benefit of the program is the opportunity to get kids out into nature where they can be active and forge a connection with the animals around them. The citizen science component, learning to identify birds and enter them into eBird, also teaches kids that their observations can help scientists learn more about topics like bird migration.

Of course, many teachers and students may feel they don’t have enough experience with birds to teach this curriculum. One key component of the program is training the teachers and students to observe and identify birds. They learn to do this by observing physical characteristics, but also by looking at behavior, habitat and what birds are found in the area. The program also shows that we often know more about birds that we think. Almost everyone can already distinguish a duck from a seagull or an egret.

The BirdSleuth training workshop was hands down the best training experience I’ve had to date,” commented Falon Cartwright, Preserve Manager for the Bahamas National Trust Leon Levy Native Plant Preserve in Eleuthera, Bahamas. “The curriculum is well designed, thorough, and super engaging and the level of organization and expertise demonstrated by our facilitators made the three days an absolute pleasure. I am so excited to use the BirdSleuth curriculum to encourage young people in Eleuthera to learn about and value our local birds.”

Israel Guzman (Sociedad Ornitológica Puertorriqueña Inc., Puerto Rico) had this to say: “Birds Caribbean, the Cornell Lab of Ornithology and the Bahamas National Trust teamed up to bring us one of the best workshops ever. Learning by doing and sharing experiences made us all get the most from this workshop based on the BirdSleuth Curriculum. The whole experience will be replicated to provide students with the right tools to reconnect them to nature, and lead them to love and care about birds and conservation.”

Birds are a powerful tool to help kids and people of all ages connect with nature and develop a conservation mentality. Birds are fantastic ambassadors for nature because they are found everywhere, easy to see and identify and endlessly fascinating. Studying birds is a great tool for encouraging interest in both science and in the outdoors. Collaborative activities like many of the ones in the BirdSleuth program also help kids learn teamwork and cooperation skills.

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

Dan Stonko, an undergraduate at the University of Maryland, Baltimore County, takes us on the journey of his first experience with international fieldwork: into the wilds of the Bahamas to unravel the mystery of where Bahama Orioles nest.

I can’t remember the last time I was so thrilled to be awake at 4:30 in the morning. There I was – meeting our team and boarding a plane to Nassau as part of a research team studying the Bahama Oriole (Icterus northropi)– considered to be one of the most endangered songbirds in the Caribbean. One thing kept running through my mind: if at the very start of college someone had asked me what sort of opportunities I thought I’d get as an undergraduate, I couldn’t have dreamed this would be one of them. What awaited me in the Bahamas were two incredible weeks filled with intense fieldwork, scientific discovery, a fair share of car troubles, and as much exploring as we could possibly squeeze into our spare time.

The Backstory

Here’s a quick summary of what our team was doing and how I ended up in the middle of it all. In 2015, Dr. Kevin Omland, my professor at the University of Maryland, Baltimore County (UMBC), began the Bahama Oriole Project in collaboration with Bahamas National Trust. At that time, the latest research on the species had come out in 2011 and indicated a declining population of less than 300 individuals. However, conservation efforts were hindered in large part due to the lack of sufficient information about this species. The Bahama Oriole Project was launched with the goal of reversing the bird’s decline through research, conservation and education. I was fortunate enough to join the team, and funded in part by a grant from The Explorers Club Youth Activity Fund, take part in this field research trip alongside Dr. Omland and three other UMBC undergrads. This was the Project’s first official research trip and my first experience with international fieldwork.

The Research

On that oh-so-early early morning in May 2016, we flew from Baltimore to Nassau, then chartered a six-seater plane that took us to the only place in the world where the Bahama Oriole is found today: Andros. It’s the largest and least developed island in the Bahamas with a population of nearly 8,000 people. Andros is a sort of island complex made up of three major landmasses (North Andros, Mangrove Cay, and South Andros) and smaller cays that are separated by channels and creeks. For now, our research is primarily confined to our study site in the northern portion of North Andros. Once we landed, we headed to where we’d be staying (Nicholls Town). After unpacking, the exploration finally began.

When I take a step back for a second, the thought of taking four undergrads that don’t know each other to another country for two weeks of field research might seem a little crazy. But to what I’m sure was Dr. Omland’s delight – our team ran like a well-oiled machine from day one. While we did spend some of our time all working together, each undergrad had a particular focus throughout the trip. Jennifer Christhilf was our team’s Magellan; she traversed our study area recording GPS points and habitat measurements to construct habitat maps of the island. Alex Scarselletta and Michael Rowley concentrated on the population surveys. Roni Rolle, a local college student from the Bahamas Agriculture & Marine Science Institute (BAMSI), also joined our team. His expertise on all-things-local was a tremendous contribution to our work. Before our UMBC team even reached Andros, he worked in the field to collect preliminary data by locating orioles and nests. A few days before we arrived, he found something particularly compelling while working in a pine forest– an apparent active oriole nest in a pine tree (Pinus caribaea).

Out of context this finding may seem insignificant, but here’s the thing: all previous research indicated that the orioles nest primarily in nonnative coconut palms (Cocos nucifera) in or near residential and agricultural (anthropogenic) land– but never in pine forests. Not only that, the research suggested that the oriole is dependent on the anthropogenic habitat for nesting. These findings formed the basis of what we thought we knew about the Bahama Oriole and had several important implications. Notably, these assumptions played a defining role in population estimates; and also in determining what conservation efforts would be most effective to protect the species. Any real discovery of pine forest nesting would then have the potential to shake up the basic understanding of Bahama Oriole breeding ecology and affect research and conservation efforts.

On our first day of fieldwork, Roni took us all to the nest site and to our surprise, there it was: an active nest in the pine forest, and actually in a Caribbean pine. This turned out to be a nest of two adult Bahama Orioles that successfully fledged young several weeks later. One of our questions now became whether this nest was an outlier or whether we were on the cusp of an important discovery.

Finding Nests in Understory Palms

Roni and I ended up working together for most of the trip. We primarily focused on finding orioles and locating nests, especially in the pine forest. All the while- the pine nest was in the back of our minds. What if there were more nests in pine trees? Even more likely, we speculated: what if they’re also nesting in the native palms within the pine forest understory?

During their randomized point counts, Michael, Alex and Dr. Omland heard Bahama Oriole vocalizations at several other locations in and near pine forests. Using these locations as leads, Roni and I scouted them out to see what we would find. One morning in the later portion of the trip we followed one of these leads, which took us down to the southern part of our study site (near the nest Roni found before we arrived). The area is an expansive pine forest with little human development nearby. We parked our car just as the sun was rising and set out hiking. To our surprise, we quickly found a pair of orioles. After over an hour of vigilant following, the pair eventually flew too far away to track. We headed back to the car, glad to have found the pair but sorry that we had lost track of them. As we packed our things up, Roni and I immediately froze at the same instant. We had both just heard it – the distinctive song of the oriole. The bird was perched in a nearby understory palm, but it quickly flew further into the forest.

Now, it is worth taking a moment to describe the typical understory of pine forests on Andros. First of all, the ground is sharp, jagged limestone that makes simply walking an ankle-twisting hazard. Worst of all though, the understory is often dominated by poisonwood (Metopium toxiferum), a type of tree in the same family as poison ivy. Poisonwood can cause some wicked blisters if you contact any part of the plant.

Once we saw the bird fly deeper into the forest, I think we both had the same internal questions: how badly do we really want to follow this bird/potentially find a nest, and would be it be worth the potential poisonwood rashes?? Throwing caution to the wind, we sprinted after the bird and into the forest in close pursuit. All in the name of science! We did our best to keep it in our sights and listened carefully for any vocalizations.

In retrospect, I can say that the poisonwood rashes I ended up getting several days later were definitely worth it, because after nearly 20 minutes– we found the nest! On the underside of a frond, the oriole had built its nest in an understory thatch palm (Leucothrinax morrissii). After tracking the bird to the nest, another individual soon appeared. We stuck around for a while to gather measurements, observe more behavior, and– of course– take a nice selfie with the nest tree. I was particularly surprised by the pair’s nonchalance with our presence. Before we knew it, the female was hard at work building her nest once again. She hopped from frond to frond on a nearby palm and skillfully ripped off fibers. Then she flew back to the nest tree and artfully wove the pieces together. How cool was this?! Not only did we find the nest in an unexpected place, but we also got front row seats to watch the nest being built!

In the following days, our team found several more pairs with territories in the pine forest, and we even found a second nest in an understory thatch palm about one mile from the first understory palm nest. As the trip drew to a close, our team of undergraduate researchers was quite proud of our work. We all made significant advances on our respective research projects, plus spent some free time exploring, swimming in blue holes, and snorkeling in the ocean.

What’s Next?

Our ability to protect any given species is contingent on having a relevant and accurate understanding of the species. These findings revealed, for the first time and contrary to previous assumptions, that pine forests on Andros are in fact a viable breeding habitat for Bahama Orioles. This new information elevates the significance of the pine forest habitat in terms of oriole breeding ecology. These findings also suggest a need to revisit prior population estimates, since their accuracy depended on the supposition that orioles don’t breed in the pine forests. The team is looking for funding to build on our initial findings and conduct comprehensive point counts across the entire Andros complex.

The discoveries and knowledge gained on this trip (through documentation of pine forest nesting, population sampling, habitat mapping) together allow the Bahama Oriole Project Team to refocus future research by refining the questions we ask. For example, we now know that the orioles nest in the pine forest; this provides unprecedented and critical justification to investigate the potential predators that are present in and/or unique to this habitat. Feral cats, for example, are infamous for their ability to prey on birds. We know they are present in residential areas throughout Andros, but what about deep within the pine forests? If so, could they (or other predators) threaten Bahama Oriole fledglings? On a second trip to Andros this past January, I used motion-activated trail cameras to see what exactly was lingering in the pine forests…but that’s an exciting story for another time.

Working to Save and Protect what’s Ours— That’s our CAWS

Scott Johnson, Science Officer with the Bahamas National Trust, shares the work that he and his fellow conservationists are doing to help raise awareness about the issue of wildlife smuggling.

As a Caribbean native, I can wholeheartedly understand people’s obsession with our region. The lush green vegetation, white sandy beaches, turquoise waters, delicious food, and warm tropical climate are all hallmarks of the Caribbean experience. Every year many people, aka “snowbirds” flock to this region by the millions for a welcome respite from the frozen north.

In addition to “sun, sea and sand,” visitors also enjoy the Caribbean’s abundant wildlife, including the chance to spot spectacular native birds like parrots, trogons and todies, swim with sharks and rays, snorkel on a tropical reef, interact with rock iguanas, and even watch sea turtles laying their eggs in a nest they dig right on the beach. Unfortunately, some people want to do more than just observe the wildlife—they want to take a souvenir home, purchasing wildlife products for fashion, pets, and novel foods. This is causing a serious threat to the long-term survival of many native species.

Nesting trees are usually damaged by poachers so that they cannot be used by parrots in the future—a hole is slashed or the tree is chopped down, and the eggs or chicks are stolen. This is tragic because good nesting trees are in short supply. (Photo by Dax Roman)

The Caribbean is a virtual treasure trove of biological diversity. In fact, it is one of the most important biological hotspots in the world, home to thousands of endemic plants and animals. For example, 172 species of birds are Caribbean endemics, found no place else on earth. Many of these species are found on only one or two islands in the entire region. The novelty of these species unfortunately makes them key targets for smugglers.

Wildlife smuggling is one of the largest illegal activities in the world, a multi-billion dollar industry worldwide. Every year, tens of thousands of animals and animal products are smuggled to places like Asia, the US and other countries to satisfy people’s insatiable appetites for the new and exotic. In Trinidad and Tobago, birds like the Chestnut-bellied Seed Finch and Blue-and-Yellow Macaw are key species targeted by smugglers. In 2011, 74 eggs from both Black-billed Parrots and Yellow-billed Parrots were smuggled out of Jamaica into Austria in rum cake boxes by tourists visiting Jamaica. On the island of Hispaniola, Hispaniolan Parrots have been captured and sold in the wildlife trade and are illegally kept as pets, while a single St. Vincent Parrot is said to be worth $100,000 on the black market.

What’s being done to help curb this threat in the Caribbean?

Law enforcement is an extremely important tool in the battle against wildlife smuggling. Sadly, protection of native wildlife from illegal capture and smuggling has not been a major priority for many Caribbean countries. In addition, many enforcers do not have a well-rounded knowledge about their native species. This is where wildlife sensitization comes in.

For the past two years, the Conservation Leadership in the Caribbean (CLiC) Program of the US Fish and Wildlife Service has been training emerging young conservation professionals from around the Caribbean to tackle wildlife conservation problems in the region. Several of the participants formed a group called Team Traffic, and took on the challenging issue of wildlife smuggling in their home countries, the Bahamas and Trinidad and Tobago. Over the past year they have been assisting in the training of enforcers in each country, giving them the knowledge they need to properly identify animals in their country and put more emphasis on the protection of native wildlife.

Team Traffic has also created a Facebook page called CAWS-Caribbean Against Wildlife Smuggling, to help with outreach and education. International transportation companies such as JetBlue are helping to raise awareness through a public education campaign that advises travellers not to carry any wildlife products from countries visited.

In July 2016, The Bahamas hosted the Regional Wildlife Enforcement Workshop which brought together heads of enforcement agencies from across the Caribbean and International organizations such as CITES and the US Fish and Wildlife Service. The successful meeting led to the recommendation of the establishment of a Caribbean Wildlife Enforcement Network aimed at improving wildlife enforcement cooperation in the region.

CLiC’s Team Traffic group will continue to work with partners both locally and internationally to educate enforcers on the threats of wildlife smuggling in the region. With all of us working together, we will be a strong force against the ever-present threat of smuggling. Please support our CAWS!

What you can do to help

  • Don’t purchase items such as coral, products made from turtle shells, feathers, or any exotic animal product, as you may be helping to fuel the illegal wildlife trade market.
  • Never buy wild-caught birds.
  • Report the capture and sale of wild birds to the authorities.
  • Plant native trees and shrubs in your yard and support forest reforestation efforts.
  • Enjoy the beauty of the animals in their natural habitat to ensure them for future generations. If everyone puts in a concerted effort to learn about wildlife and wildlife smuggling, our region will be one step closer towards eradicating this illegal activity once and for all.
