We have exciting news about how to participate in the Caribbean Waterbird Census (CWC) using eBird! Whether you’re a long-time contributor to the CWC, use CWC protocols in eBird, or are just getting started with waterbird surveys in the Caribbean, there’s now a better and easier way to ensure your data is added to this incredible long-term program!
The Cornell Lab of Ornithology has launched a powerful new feature, eBird Projects, that makes it easier than ever to take part in targeted data collection efforts like the CWC. If you’ve contributed to our amazing 16-year citizen science database using the CWC protocols in eBird in the past, the process has now changed slightly in eBird.
You no longer need to search the dropdown menu for CWC protocols in the “Other” options. Now, simply join the CWC project in eBird and select “Caribbean Waterbird Census” from your projects when starting a new checklist. This ensures your counts are properly tagged and included in the official CWC database. Read on for step-by-step instructions for both the eBird app and website. You can also learn more about eBird Projects here.
How to join the CWC Project
Great news—if you’ve ever submitted a checklist using a CWC protocol—you’ve likely been automatically added to the project! Check out the CWC project pages here to confirm you’ve joined, explore CWC stats, see the latest checklists, and meet our “Top CWC eBirders.” If for some reason you’ve not been joined, just go to the ‘about’ section on the project page, scroll down, and click “Join Project.”

Make sure your checklists count as CWC!
Once you’ve joined the CWC project, it’s easy to add your CWC lists to our database on the eBird app or on the website. Here’s how:
CWC in the eBird Mobile App
IMPORTANT: Projects are only supported in version 3.1.3 or later of the eBird app. If you’ve joined a Project but are not seeing it on eBird Mobile, go to Settings>Check for updates in the app—you may need to update in the Google Play Store (android) or App Store (iPhone). Project options will not appear immediately after the update, you will need to wait for a few minutes before you see this.
Once updated:
Launch the app.
Tap “Choose projects” above the “Start checklist”’ button.
Select the CWC project, and, if you like, ask the app to remember this choice for future submissions. If you do this CWC will appear automatically above the “Start checklist” button next time you use App.
Tap “Continue” and do your count (it’s that simple!)
Next time you do a count at a Caribbean wetland, select “Caribbean Waterbird Census” above the “Start checklist” button.
CWC on the eBird Website:
Go to the Submit page.
Use the “Choose a Project” dropdown to check the box next to “Caribbean Waterbird Census.”
Then follow the steps below to add your list details as normal.
For your CWC lists, be sure to:
Do a complete checklist of all birds you were able to identify by sight or sound (to the best of your ability). Check out why this is important and best practices for ebird here.
Select the appropriate protocol (Traveling or Stationary) before submitting.
Now that you’ve joined the project, you can easily identify which of your eBird checklists are part of the CWC! Just view your checklists in eBird—those included in any eBird project will display a small green circular icon in the upper right corner.
Click on the list to see details, including which project it is associated with.
What happened to the CWC Area Search Protocol?
The CWC Area Search protocol was previously available for counts where it was possible to move through the habitat on a predetermined route to count all the birds in the area. Now that eBird allows you to enter the survey area size manually as part of a Traveling Count, this separate protocol is no longer needed. If you previously used Area Search, we recommend switching to the CWC Traveling Count—especially for sites with trails, boardwalks, or navigable waterways. Just be sure to enter the Surveyed Area (in hectares or acres) in your checklists!

Why your participation matters
The Caribbean Waterbird Census is a long-term region-wide initiative to track birds using Caribbean wetlands, identify the threats they face, and raise awareness. Your data plays a critical role in shaping conservation actions and priorities across the Caribbean.
The CWC has compiled thousands of checklists—thanks to YOU! Visit our CWC eBird Project Page to explore the impressive stats and see the top contributors.
While the annual regional count takes place from January 14 to February 3—providing a valuable winter snapshot—CWC counts areimportant year-round, especially during fall and spring migration. Whether you’re monitoring resident or migratory species, every count matters.
If you’ve never done a CWC count before, now is the perfect time to start. Just remember to select the CWC Project in eBird every time you do a count at a Caribbean wetland.

Enthusiasm is a key ingredient when observing, teaching, and talking about birds. For Ajhermae White, organizing a shorebird education initiative funded by BirdsCaribbean on her native Montserrat was a learning experience for her as well as her audiences, and a deeply satisfying one all around. Here is Ahjermae’s account of her journey as a shorebird educator – with young children, frigatebirds, and Government officials thrown into the mix.
The ‘Education on Shorebirds in Montserrat’ project is an initiative carried out by the island’s Department of Environment and sponsored by BirdsCaribbean. The aim is to spread awareness of shorebirds and their habitats. Once island residents learn more about these birds and understand their significance, the likelihood of threats to shorebirds, such as habitat destruction and human disturbance, will be reduced. As the project leader, I was really excited about the possible outcomes of this initiative.
The journey of being a shorebird educator has been a fulfilling experience. It has been a real privilege for me as the project leader to be given the opportunity to educate the local populace, in schools and among the general population about this fascinating topic. This has afforded me personal growth in addition to the enormous pleasure of sharing my passion for birds and their habitats.
Cleaning Up the Beaches Where Shorebirds Hang Out

The first major activity of this project was hosting a beach clean-up, in August 2020. Together with my colleagues from the Department of Environment, we brought the local community together to clean a shorebird habitat ahead of the migratory season.
We chose Marguerita Bay, which is located on the eastern side of the island, for this clean-up. Debris is constantly deposited on this beach as a consequence with the tides of the Atlantic Ocean. Nonetheless, this beach has been a popular site for shorebirds on Montserrat during the migratory season.
It was a good turnout of volunteers of all ages, from various community groups. I found it quite surprising to see the various types of items that were collected from the beach. These included items such as fishnets, clothing items, shoes, and even a 20 pound propane bottle! This clean-up was a success. An amazing 1,300 pounds of trash was removed from the beach. As such, the beach was much cleaner for the 2020 fall migrants.

Working in Schools and Communities

During the month of October 2020, we were out in the schools and communities, conducting outreach sessions. We gave presentations and organized field trips. We conducted outreach sessions with The Rotaract Club; grade classes in three primary schools; two groups with members of the public; and last but not least, an After School Club of four to six-year-olds.
For most of the school engagements, we made presentations in the afternoons. The following morning, we took the students out on the field trip, as soon as the school day started.
The students listened intently and participated actively in all the presentations, which was impressive. We talked to them about “What is a shorebird?” and went on to discuss their habitats, feeding habits, and threats to their survival. We then described some common shorebirds on Montserrat.

We made sure that these presentations included many pictures and videos of shorebirds and their habitats. Some classes had interesting questions. I specifically recall that during one presentation a student asked whether the Killdeer was the adult version of the Semipalmated Plover. When the student asked this, I felt a sense of gratification. This not only demonstrated that they were paying attention but that they were engrossed sufficiently to spot the similarities and differences and between the different species.
After every presentation, we gave the students a short quiz with spot prizes. After the quiz, every student was given a token (badge, sticker, pamphlet, or bird band). Needless to say, they were very excited to be “little ambassadors” for migratory shorebirds with their stickers and other tokens.
Meanwhile, Out in the Field…Frigatebirds Were a “Hit”
Our first stop for every field trip was the recently-cleaned Marguerita Bay, where students were thrilled to see shorebirds like the Sanderling, Pectoral Sandpiper, and the Semipalmated Sandpiper. However, as the month of October progressed, there were fewer sightings, as the shorebirds were moving on.
During every field trip at Marguerita Bay, we could count on the Magnificent Frigatebirds to put on a show by flying very low and putting on acrobatic performances when swooping down to drink water from the pond. It was as if they enjoyed the attention from the young bird-watchers, who could observe the sexual dimorphism in this species.
Even if there weren’t many shorebirds to see at the beach at the time of the visit, the Frigatebirds captivated the students. The After School Club birders (4-6 year olds) were mesmerized by the Magnificent Frigatebirds. I recall that I wasn’t certain whether these little ones would understand terms like “female”, “male” and “juvenile,” so to simplify for these kindergartners, I told them which frigatebirds were “girls”, “boys” and “babies”. They kept shouting out “That one’s a baby bird!” They were so funny.
Some of the information about the shorebirds was in Spanish, so I made sure that any student who spoke Spanish as a first language was able to see the Spanish names as well for the various species. Those students also received a Spanish Shorebird poster.
All Went Well With the Student Birders!

The second stop during the field trips was to Carr’s Bay. This area is near a busy road so we always took extra precautions when visiting this area. Students spotted species like the Sanderling, LesserYellowlegs, GreaterYellowlegs, SolitarySandpiper, and others wading in the water. There were also a few other wetland bird species that the students were able to identify, such as the Common Gallinule and the Snowy Egret.
When we returned to the classroom we distributed refreshments and provided additional tokens. I gave students a shorebird word search that I created online, to help them remember the names of the shorebirds of Montserrat.

Although I always felt a little anxious before leading a field trip, I felt relieved afterwards, because they were successful and went ahead without mishaps. This was quite a responsibility for me, especially with the smallest bird enthusiasts. The students were able to see shorebirds and many other birds. Fortunately, there were no accidents during the field trips and even if it was a rainy day, the rain stopped long enough for the field trips to take place.
Engaging with the students was really gratifying. After the first few educational events, I started feeling more confident about putting myself out there to educate more students and the public. The enthusiasm that the students displayed showed me how much potential there is to impart knowledge to the younger generation, so that they can become more intensely aware of the avian biodiversity on Montserrat.

Radio, a Powerful Medium for Reaching People
We used radio a great deal during this project. We recorded a few radio spots to inform the public about shorebirds, their habitats and migration, playing shorebird calls to grab the listeners’ attention. The spots also informed listeners about some of the threats that these birds face, such as habitat loss and pollution. A few of our outreach activities were scheduled around World Migratory Bird Day (WMBD) so this celebration got coverage on the local news and the public was informed about the activities planned.
The Department of Environment was featured on the Ministry of Agriculture’s radio program called “MALHE VIBES” in October. On this live program, James ‘Scriber’ Daley (Forest Ranger) and I spoke about shorebirds and their habitats, informed listeners about our activities throughout the month, and used the opportunity to invite people to a public shorebird educational event. (See the end of this post for links to all Ajhermae’s radio appearances during this project!).
Great Support for Public Events – and a Government Minister, Too
We hosted public events to educate people in the community about shorebirds and give them opportunities to see shorebirds in their habitat. We advertised these events on the radio and on Facebook. I was really grateful to my co-worker, Thiffanie Williams, who created digital flyers to advertise the public events of this project.

For the public events Scriber and I conducted presentations, starting at 6:30 am. This presentation covered the same topics as the school presentations – but this time, people of all ages attended these sessions. We also gave a mini-quiz to participants, with the opportunity to win a BirdsCaribbean tote bag. After stocking up on refreshments and equipping them with binoculars, the participants boarded a bus at 7:00 am. Just like the school field trips, we took the participants to Marguerita Bay and then to Carr’s Bay. At Marguerita Bay we didn’t see as many shorebirds as we had hoped to see but some seabirds were present.

The radio sessions had clearly paid off, as residents of all ages attended the public birding events. I was particularly grateful that the Minister of Agriculture, Lands Housing and the Environment (MALHE), Hon. Crenston Buffonge and the Parliamentary Secretary, the Hon. Veronica Dorsette-Hector, each attended one of our public outreach sessions. It made me really pleased that these members of Parliament took part in these educational events and publicly showed their support for the project. This gave me hope for the future of wetlands on Montserrat.

Carr’s Bay never disappointed us! On the first public birding trip, we saw fifteen different bird species at this site, including various species of shorebirds, like the Spotted Sandpiper and the Least Sandpiper! The first public birding trip was quite fulfilling for me because I saw two bird species that I had never seen before: the Merlin, and one that had eluded me many times – the Belted Kingfisher. The Minister jokingly commented that perhaps he and the other participants brought the good luck that allowed me to see these species.
It was quite satisfying to see when someone got an ‘aha moment’ after learning something new or finding out the name of a bird that they’ve often seen. A young girl, Kearah Ryan, who joined the second public birding trip, wrote a lovely blog about her experience. During that trip, Scriber and I were interviewed live on the radio by phone, informing the listeners about shorebirds, their habitats, migration, and the importance of protecting these birds. To my further delight, this clip was featured on ZJB Radio on the local news the following Monday. This served to boost my confidence as a shorebird educator.

An Impactful Project, a Great Personal Experience

Overall, this project has been a resounding success! The Covid-19 pandemic had minimal impact on this educational project, as we have been fortunate in that Montserrat recorded no active cases between July 2020 and February 2021. With the use of the radio spots, the radio program, and the news, we effectively reached and educated many people locally about shorebirds and raised awareness about the threats that this group of birds face. So far we have directly engaged 145 persons, including two elected politicians. The feedback has been positive!
It is fair to say that I experienced personal growth while undertaking this project. It allowed me to sharpen my organizational skills, as quite a lot of planning and coordination was required to organize the clean-up and field trips. Additionally, with the wide coverage through the media and in-person presentations, my communication skills were also enhanced. As a direct consequence of this and the feedback I received, I am more confident to take on other projects in the future. I am therefore thankful to BirdsCaribbean for firstly, igniting my interest in birds, which allowed me to gain knowledge about avian species. Secondly, through their generous funding of this project I had the opportunity to educate Montserrat about this fascinating group of birds.

This year marked the 12th anniversary of the Caribbean Waterbird Census (CWC). Shanna Challenger and Britney Hay from the Environmental Awareness Group (EAG) update us on the highlights of this years CWC activities on Antigua. Find out what the group saw during their citizen science surveys and who made the winning mask in their fun and creative ‘Bird Mask-erade’ !
We’ve all heard the age-old saying “birds of a feather flock together” – but when counting birds, we realize that birds not of a feather will still flock together, making counting an even more challenging experience, requiring a sharp eye, and close attention to detail.

It’s a beautiful Sunday evening, and the sun is beginning to make its descent. You arrive at the mangrove, armed with your mask, binoculars, reusable water bottle, and most importantly, insect repellent. White feathery heads dot the lush mangrove, and you get into position, ready to count the mysterious colony of egrets or “garlings”. As you look through your spotting scope and begin your count, you take a closer look and realise that the seemingly monotonous flock of egrets also includes other species, such as Yellow-Crowned Night Herons, Brown Pelicans, and Little Blue Herons. As you excitedly record the numbers of birds seen, you look around for the final three minutes, and a majestic Osprey flies overhead just in time to be included in your count.
What’s described above is a typical experience of being a birder and participating in the annual Caribbean Waterbird Census (CWC). This year marked the 12th anniversary of this region-wide wetland bird and waterbird monitoring program, spearheaded by BirdsCaribbean. The CWC, which took place between January 14th and February 3rd across the region, aimed to raise awareness of wetland birds and their habitats by engaging different agencies and individuals in monitoring and conservation. Across the Caribbean, avid birders took to their favourite wetland bird sites to record the number and species of wetland birds in the spirit of conservation.

Members of the EAG’s birding club, the Wadadli Warblers, and friends were sure to get involved in the CWC action this year. The 21 participants were split among three different wetland sites: the Fitches Creek Mangrove, McKinnon’s Salt Pond, and Nevis Street Mangrove. Except for the Nevis Street Mangrove, each of these sites are considered Important Bird and Biodiversity Areas (IBAs) because of the notable species and numbers of native and migratory birds that they regularly support.
At each site, CWC Level 2 counts were conducted by the respective teams, affectionately named the “Nevis Street Noddies”, the “McKinnons Mallards” and the “Fitches Creek Falcons”. During the census this year, a whopping 42 species of birds were seen between the three sites. Preliminary findings showed the evidence of nesting White-Cheeked Pintails, as ducklings were observed at McKinnons; and the surprising presence of Laughing Gulls, which are not usually seen until later in the year. Collecting this data is invaluable for monitoring the health of waterbird populations and their habitats in our Antiguan wetlands. It is beneficial to both birds and people, since we rely on the same habitats for our health and well-being.

Unfortunately, each of these sites were under pressure, threatening the bird species that lived there. Pollution through illegal dumping, noise, invasive species, and infrastructural developments were all examples of this.
This year’s census was the most robust CWC data collection effort to date and we applaud our teams for their contributions as citizen scientists. For the grand finale of the CWC activities, the EAG encouraged the Wadadli Warblers to participate in a Bird Mask-erade, where members were tasked with designing a face mask inspired by their favorite wetland bird. In addition to celebrating the CWC, the friendly competition sought to link our culture with our love of the environment, while providing a keepsake of our current times during the pandemic. The winner of the competition, Auriel Hunte, won a Birds of the West Indies field guide (new Second Edition!), written by renowned author Herb Raffaele, and a $50 food voucher for her feathery Snowy Egret-inspired mask.

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

THE RICH DIVERSITY OF TRINIDAD AND TOBAGO’S SHOREBIRDS
Shorebird diversity in Trinidad and Tobago is particularly rich. Of the 48 shorebird species recorded to date, some of which are European vagrants, 23 species were observed during the 2018 to 2020 surveys. Our surveys, and those by Morrison and Ross and others, found that the Semipalmated Sandpiper is by far the most common species, representing around 90% of shorebirds tallied in the country. Other common species are Western Sandpiper (see photo), Semipalmated Plover, Lesser Yellowlegs, Stilt Sandpiper, Whimbrel, and Willet. Historical accounts suggest a similar mixture of species
SADLY, SHOREBIRDS IN DECLINING NUMBERS
The February 1982 aerial survey of Trinidad by Morrison and Ross documented more than 13,600 Nearctic shorebirds. But there is worrying news. The maximum number of birds seen on the 2018 to 2020 surveys was 4,174 (September 2018). This disturbing decline, which is described in more detail below, matches up with the USFWS and CWS findings. Although an accurate estimate of the percent decline is difficult, current shorebird populations are likely only between 20 to 30% of 1982 levels.
WHERE WERE WE LOOKING FOR SHOREBIRDS?
Some of the most important habitats for shorebirds are on the west coast of Trinidad. In fact, the west coast mudflats are designated as an Important Bird Area (IBA) by Birdlife International. The area between the southern end of Caroni Swamp and south past the Couva River mouth to around Pointe-à-Pierre seems to be particularly good for shorebirds. Where the mudflats look greenish in color, there is a thick slurry of biofilm (i.e., diatoms, bacteria, organic detritus, and benthic invertebrates), a very important food source for Semipalmated and Western sandpipers. Morrison and Ross found that about 99% of all shorebirds observed on their aerial surveys were on the west coast mudflats, which aligns with the approximately 95% of shorebirds documented from 2018 to 2020. Very few shorebirds have been observed on the northern, eastern, or southern coasts.

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

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

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

Apparently, this loss of the mudflats that provide so much food and foraging for small shorebirds (Semipalmated and Western Sandpipers) appears to be a cause of the considerable declines of these charming, once abundant little birds between the 1982 and the 2018-2020 surveys.
Following the construction of the Orange Valley fishing pier, there has been a dramatic decline in the surrounding mudflats, with a rapid expansion of mangroves in the area.

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

It’s that time of year again – spring migration! Migratory birds have started making their way to the temperate areas of the globe for breeding, Some of these birds have spent the entire winter in the Caribbean and others are passing through as part of a longer journey. In both cases, the Caribbean provides essential habitat that supports these fearless travelers. Safe, clean places to rest and refuel are critical to their survival.

Some of the longest trips made this spring will be completed by the arctic-breeding shorebirds. If you catch a glimpse of a Red Knot in the next few weeks, you are seeing it on just a small part of its 9,300 mile (15,00 km) journey! Shorebirds are both incredible athletes and world travelers: they can travel hundreds of miles a day without rest and pass over continents in weeks.
Capturing data of birds during migration is vital to understanding their status, distribution, and how they are using sites in the Caribbean throughout their life cycle. While you are out birding don’t forget to log your observations in eBird Caribbean. If you are visiting a wetland, please do a Caribbean Waterbird Census (CWC) count! The regional count occurs in January and February, but CWC data is collected year-round! When entering your data on eBird, on Step 2 “Date and Effort” page, be sure to choose either the “CWC Point Count” “CWC Traveling Count” or “CWC Area Search” observation type. (you can also choose one of these options if you are using the EBird Mobile app – adjust your settings – choose eBird Caribbean as your portal and the options will show up!)
Is that a Least Sandpiper or a Western?
Earlier this year, we redesigned an existing poster of common shorebirds in the Caribbean which features many of the sandpipers, plovers and larger shorebirds that you may see while birding. This poster is a great resource because: 1) it shows the relative size of the shorebirds to each other and 2) all the birds are in their winter plumage. In their non-breeding plumage shorebirds – especially peeps – can be challenging to identify. We hope that this resource is a helpful guide for those learning their shorebird identification.
The poster is also available in Spanish and French. Below the English common name and scientific name, the common name of the bird appears in Spanish for Cuba, the Dominican Republic, and Puerto Rico. For example, the Red Knot has three Spanish common names: Zarapico Raro (Cuba), Playero Gordo (Dominican Republic), and Playero Pechirrojo (Puerto Rico). If only two Spanish common names appear, this indicates that two of these three countries have the same common name for the bird.
Do you have access to a large format printer and want to have a hard copy of this beautiful resource? The poster is the perfect addition to wildlife offices, public education spaces, or to have on hand for events like presentations and bird festivals! Larger versions of the posters can be downloaded here: French, English and Spanish.
We very much appreciate the National Audubon Society and the Bahamas National Trust allowing us to redesign their original poster and for Manomet’s input during the process. We thank the Canadian Wildlife Service for supporting poster printing costs in 2019. Participants at the Conserving Caribbean Shorebirds and Their Habitats Workshop were treated to small versions of the poster thanks to a generous donation from the Puerto Rico Department of Natural and Environmental Resources.
We have exciting news about how to participate in the Caribbean Waterbird Census (CWC) using eBird! Whether you’re a long-time contributor to the CWC, use CWC protocols in eBird, or are just getting started with waterbird surveys in the Caribbean, there’s now a better and easier way to ensure your data is added to this incredible long-term program!
