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.”
New to CWC? No problem! Just visit the CWC Project Page and click“Learn how to join.” Review the info about the project, scroll to the end and then click “Join Project.” If you are not logged into eBird you will be prompted to “Login to Join Project.”
Anyone can join—we welcome new contributors!

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.
Seven spectacular species of egrets and herons in the Caribbean can have all-white plumage. You read that right—seven! With so many sleek, long-legged, long-necked, all-white waterbirds around, telling them apart can be tricky! But don’t worry—if you look closely, each species has distinctive features that set it apart. Our helpful tips and ID graphics will have you spotting those differences like a pro. Dive in to level up your egret and heron ID skills!
When identifying an all-white egret or heron, focus on a few key features:
Size – Compare it to nearby birds; some species are much larger than others.
Bill color – This varies among species, including yellow, black, and even bi-colored bills.
Leg and foot color – These can be helpful, but may be hard to see if the bird is standing in water.
Breeding plumage – Some species develop special plumes or color changes around the eyes (lores) in breeding season.
Plumage variations – Some birds are only white as juveniles, while others have both white and dark morphs.
1. Great Egret
We’re starting off easy! The Great Egret stands out due to its large size, yellow bill, dark legs, and long, S-curved neck. It favors large freshwater and saltwater swamps, grassy marshes with stagnant water, river banks, and turtle grass beds in shallows behind reefs.
The Great Egret is a common year-round resident in The Bahamas, Greater Antilles, Antigua and Guadeloupe; and an uncommon one in the Virgin Islands. It is a common non-breeding resident in the Cayman Islands, St. Barthelemy, and Barbados. While generally uncommon elsewhere in the Lesser Antilles, local numbers are augmented from September to April by migrants from North America.
Breeding season tip: Great Egrets breeding in the Caribbean develop bright green lores (the area of a bird’s face between its eye and bill), more orangey bills, and extravagant plumes (as shown in the photo above right).
2. Great Blue Heron: White Morph
The only other large bird amongst our seven contenders, the White morph of Great Blue Heron, is very rare. This very tall and large bird is considered by some to be a separate species—Great White Heron (Ardea occidentalis). It can be distinguished from the Great Egret by its larger size, heavier bill, and dull yellowish legs. The common blue morph of the Great Blue Heron (photo below right) looks completely different with blue-gray upper parts, short black plumes on the head, and black-and-chestnut shoulder pattern.
3. Western Cattle Egret
Another all-white waterbird with a yellow-orange bill, Cattle Egrets are much smaller and stockier than our previous two yellow-billed birds. You can find this species feeding in pastures or other open habitats away from water. It is a common year-round resident throughout the West Indies. In breeding plumage, Cattle Egrets no longer makes our list of ‘all-white’ birds, as they take on a tan wash on the crown, breast and upper back. Their legs, eyes, and bill also become reddish!
4 & 5. Snowy Egret & Little Egret
These two species are nearly identical—both have black bills, black legs, and yellow feet, and both prefer freshwater swamps and saltwater lagoons. They’re even roughly around the same size! So—how do you tell these two lookalikes apart?
The first clue is in the lores: look for the yellow lores of the Snowy Egret, in contrast to the greenish-gray lores of the Little Egret. But beware, in breeding plumage the Little Egret’s lores take on a yellowish tint! This however is when clue number two becomes apparent—in breeding birds, the Little Egret sports two long, thin head plumes, whereas the Snowy Egret has shaggy plumes.
Location tip: Snowy Egrets are common in much of the West Indies, while Little Egrets are rare and mostly found in the Lesser Antilles and Puerto Rico.
6. Reddish Egret: White Morph
The medium-sized Reddish Egret comes in two color morphs: one that is all-white, and a more common dark morph that is dark gray with a reddish neck. Both morphs have dark legs, shaggy head and neck feathers, and a distinctive bi-colored bill that is pink at the base and black at the tip. The lores become bright blue during the breeding season.
Behavior tip: Reddish Egrets are known for their unique feeding style: they stalk, run, dance, and leap in the air after their prey, often with their wings spread to create shade and reduce glare.
Juvenile white-morph Reddish Egrets are all also white but they have an all-black bill—this all-black bill and their dark legs set them apart from juvenile Littler Blue Herons which are also all white, but have paler, yellow-green legs and a bi-color bill that is blue-gray at the base and dark at the tip.
You may also mix up a juvenile white-morph Reddish Egret with an adult Snowy Egret because they share an all-black bill—but remember, Snowy Egrets have yellow feet and lores. Reddish Egrets are also larger, and have a heavier bill.
To tell the dark morph Reddish Egret from an adult Little Blue Heron: bill color, as well as the size difference and the leg color are your go-to field marks! For both color morphs, the larger size and shaggy plumage on the neck will distinguish Reddish Egrets from Little Blue herons.
7. Little Blue Heron: Juvenile
Juvenile Little Blue Herons are entirely white, making them easy to mistake for other species. Look for the bi-colored bill color, which is dark at the tip with a pale blue-gray base. This rules out Snowy Egrets (all-black bill) and Reddish Egrets (pink-based bill). As they molt into adult plumage, they become a mix of white and gray before turning completely darkgray with a reddish neck. Adult Little Blue Herons can be distinguished from dark-morph Reddish Egrets by their smaller size, purplish neck and bi-color bill (blue-gray a the base with dark tip), compared to the shaggy rusty-colored neck of the Reddish Egret and bi-colored bill that is pink at the base dark tip .
Little Blue Herons favor calm, shallow waters and and can be found throughout the West Indies year-round.

Hundreds of thousands of migratory shorebirds are already on the move, and we are getting ready to celebrate World Shorebirds Day 2023! Diverse habitats and food supply make the Caribbean an attractive destination for shorebirds and a veritable birders’ paradise, so why not take part in the Global Shorebird Count this year? BirdsCaribbean has everything you need to help you #ShowUpForShorebirds (and show out!) in the best possible way.
World Shorebirds Day is held every year on September 6. This day celebrates shorebirds, their magnificent migration journeys, and most importantly, raises awareness of the threats they face and actively promotes their monitoring and conservation. The key event associated with this day is the Global Shorebird Count (GSC), September 1-7.
Across the Caribbean (and the entire globe!), groups of birders will be out looking for and counting shorebirds and recording what they find on eBird Caribbean. Some birders will go out in ones and twos; others in small groups. Wherever you are, whoever you are with, or even if you are on your own—we welcome your participation and contribution to citizen science.
This year, we have a special mission for you: we are asking you to do more than one count if possible. Read on to find out why.
Why should you #ShowUpForShorebirds?
The answer is that our migratory shorebirds are more vulnerable than ever, threatened by human activities such as destruction of their habitats, pollution, disturbance, and climate change. Recent analyses show that shorebirds in North America are declining more than any other group of birds; in fact, more than half of 28 species studied were estimated to have lost more than 50% of their abundance in the last 30 years.

The Caribbean is an important region for migratory shorebirds. They rely on our mangroves, salt ponds, beaches, sand flats, and mud flats to rest and refuel as they continue on their long migrations, or they may spend the entire winter with us.
The Global Shorebird Count helps map the distribution of shorebirds during migration and record their numbers. This data is essential to help us identify and protect key stopover and/or wintering habitats that shorebirds use. Protecting these habitats benefits people too because healthy coastal areas provide vital ecosystem services such as clean water, food, sustainable livelihoods, protection from storm surge, and much more.
Thanks to the great work you all are doing in gathering data through the Caribbean Waterbird Census (CWC) and the Global Shorebird Count, the importance of this region for waterbirds and shorebirds is becoming better understood at a rapid rate. However, scientists are telling us that to further document numbers and long-term trends, more frequent monitoring data are needed, especially during migration. Thus, this year we invite you to visit your nearby shorebird sites and carry out 2 or 3 counts a month during migration season (August-October), ideally a week to 10 days apart. If you’re able to do this, bravo, and thank you! Your efforts will help us learn much more about shorebirds in the Caribbean—you’ll be doubling or tripling your impact for shorebirds.
We can’t do it alone
Individuals, groups and communities must come together to conserve shorebirds and the habitats we both depend upon. This is why we need you to join the GSC to help count shorebirds, invite others, and share how awesome shorebirds are. You may even discover new or rare birds on your islands! Feel free to use our cool graphics to promote World Shorebirds Day (see below), and invite your friends and family to count shorebirds too.
We’ll be here to help you every step of the way.

Where to find shorebirds?
Where should you look for shorebirds? The simple answer is: anywhere there is water. This means that, as their name suggests, you can find them at the beach and on other types of shorelines. However, some shorebirds will be further inland, including in salt ponds and salinas, freshwater pools, agricultural fields, and at brackish marshes and ponds. Shorebirds will also gather on mud flats, in mangrove areas, and on tidal flats.

You may not be quite sure of the best places to look in your area. If so, why not take a look for ‘hotspots’ at your local wetlands on eBird. Just click on ‘Explore’ on the eBird Caribbean site, and find ‘Explore Hotspots.’ You can open hotspots on a map and then click on a hotspot to see what types of birds have been seen there recently.

How to participate in the count
Have an eBird account
eBird Caribbean is a critical tool for tracking and understanding bird migration and population changes—never more so than for our shorebirds. If you do not have an account, it is easy to register—here’s a quick guide to enter eBird data online.Check out our helpful video here on how to use eBird and Merlin.There is even a free eBird Essentials course to get you fully oriented. Download the free mobile app for recording your data in the field. Recording your findings on eBird is not only satisfying and enjoyable, but you are directly contributing to the global knowledge base of birds—what, when, and wherever they are to be found.
If you need help with or have questions about eBird checklists or with setting up an eBird account, do contact Alex Sansom: waterbird.manager@birdscaribbean.org
Count shorebirds
Visit your local sites where shorebirds occur and do a count. Record all the species you see and/or hear (including other non-shorebird species; see below) and how many individuals of each species. We recommend spending a minimum of 6 to 10 minutes at each site (longer if there are a lot of birds) and scanning the entire area carefully with your binoculars to detect birds, which can easily blend into their surroundings (mud, water, vegetation, etc.). Be sure to record the start time and duration of your count if you’re using a notebook (the ebird mobile app will do this for you). Start a new checklist each time you change locations.

Count shorebirds on as many different locations as you can during the Global Shorebird Count period (1-7 Sept). Then, if possible, repeat your counts at these same sites 2 or 3 times a month during fall migration (August through October). Repeated counts will greatly add to our knowledge of shorebird movements and migration patterns!
Note that shorebirds are a type of waterbird. So, any counts you do at wetlands, mangroves, mud flats, coastal areas or beaches at any time of year count as Caribbean Waterbird Census (CWC) counts. When you do your counts please choose one of the CWC protocols in the eBird app or when you submit or edit your data online. When you are using the mobile app make sure that you are using the eBird Caribbean Portal. To check or change the portal you are using, go into your settings on the app and look for “Portal” and select “eBird Caribbean.”
Each time you complete a checklist, be sure to share it with ebird username worldshorebirdsday. This will ensure that your checklists are included in data analyses for the Global Shorebird Count.

Rinse and repeat
As mentioned above, we ask that, if possible, do 2 or 3 counts at your local site or sites per month during fall migration(7 to 10 days apart is ideal). Scientists are telling us that we need more data on shorebird migration through the Caribbean, including which species pass through, how many individuals, the timing of each species’ migration, how long they stopover, where they go next, etc. The best way to get this local and regional data is through repeated counts!
Shorebird ID and FREE resources for the field
We know that Shorebirds can be tricky to identify, and some are especially difficult to tell apart. BirdsCaribbean is here to help you with some useful tools! We have a Shorebird Poster and “Quick ID Guide” to get you started as well as handy Shorebird ID cards that you can download and print featuring common shorebirds of the Caribbean.

We also have a list of some best practice tips to help make your count go as smoothly as possible. You can download and share this infographic with your fellow birders. When you go out on your survey, a spotting scope or a camera with a good zoom lens, as well as binoculars, will make for very helpful tools. They will help you get a closer look to pick out the identifying features of the birds, without disturbing them. Photos can be looked at and shared later if you have any birds that were difficult for you to identify in the field. Birding colleagues and experts can explain further if they have visual evidence of the bird! (Did we say some are quite tricky to tell apart?)
Promotional graphic templates – feel free to modify for your counts

You can also use these links to Canva to use our promotional graphics as a template (each link contains graphics in all three languages):
While counting shorebirds you may see birds with colourful bands on their legs. Do your best to record the band colors and any numbers or letters paying special attention to the location of the band or bands on the bird’s legs. Binoculars or zoom photography may allow you to clearly see the band colors and the numbers engraved onto the band – if you get a photo you will be able to send it along with your sighting. Look out for bands especially on Piping Plovers, Red Knots, Semipalmated Sandpipers, Semipalmated Plovers, Ruddy Turnstones, and Sanderlings. You can report your sightings and send any photos you have to BandedBirds.org and the USGS Bird Banding Lab, which oversee all banding in the United States.
Keep a sharp eye out for Piping Plovers, including banded birds!
There are several different projects banding Piping Plovers and if you see a banded Piping Plover you can report it to the correct person using the information below. This also provides a guide to reading the bands and the information that will be useful to send when you report a banded bird. The tips in this guide are useful for any banded birds you see, not just Piping Plovers! You can find out more about reporting banded Piping Plovers from the U.S. Fish and Wildlife Service here. This 1-page guide is available to download as a pdf here. We also have 2-page version with more information for you to use and share here. And a square infographic that you could share on social media here.

We love looking at photos of shorebirds, your local wetlands, and smiling faces. We will be excited to share your photos and findings on our Global Shorebird Day wrap-up blog! See our 2022 blog here.
If you’ve got little explorers, be sure to download the following activity* sheets and take them with you to the beach:
Beach Scavenger Hunt. This activity is suitable for children ages 4 to 7 years old. They are asked to find plants and animals at the beach.
Beach Bird Bingo. This activity is suitable for children ages 8 to 12 years old. They are asked to find items on the list four in a row, horizontally, vertically or diagonally. They do not need to touch or collect any of the items on the list.
Talk about this with your children before beginning any of the activities. They should not touch or collect items on the lists. When observing birds they should speak softly. They do not need to get close to the birds but if they need to, ask them to do so slowly and quietly. You can check off the items (with a pencil or pen), as they are located. When everyone has had a chance to look for the items listed, come back together to chat about what they were able to find or see. For example, why is the bird’s beak long and straight?
*These activities were not designed to teach a child how to name and identify shorebirds but rather to give them space to explore and feel connected to their natural environment. Parents and guardians, you will not need to worry about your own knowledge of birds or plants. All you need to do is accompany and participate with your child in these activities.
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!
