Common Caribbean Shorebird Identification

Bonaire Shorebird Identification

What are shorebirds?

Shorebirds are species that are typically found on the shore, in fresh, salt, or brackish wetlands, salt ponds, mud and tidal flats, lagoons, mangrove forests, or other coastal environments.  These birds are constantly probing or scanning the shoreline for marine invertebrates, their favorite food in many cases.  They often have specialized bills which are long, slender, and pointed, which assist with probing in mud or sand or between rocks.

Why shorebirds need the Caribbean.

Most shorebird species you will observe on Bonaire breed in northern North America, but some are resident breeders right here on the island.

Many travel long distances between breeding and wintering grounds.  For example, the Red Knot will travel 9,300 miles/15,000 km during migration. These migratory shorebirds rely on Bonaire, and other Caribbean islands, for rest and relaxation, allowing them the time and resources to refuel their energy reserves or simply spend the winter in warm conditions (over-wintering).

The Shorebird Identification Guide for Bonaire will help build confidence in identifying shorebirds you may see while birding.

Visual clues for shorebird identification

Shorebirds are notoriously difficult to identify!  Here are some tips and tricks to help you with shorebird identification.

Know what species to expect when on Bonaire.

Prepare yourself in advance so you know what species to expect when on Bonaire.  The Bonaire Shorebird Identification Guide provides visual clues to the most common shorebirds observed here, as well as size, expected habitat, and similar species.

For shorebird identification, note the bird’s shape and size first.

The first thing to note is the bird’s shape because, with shorebirds, the plumage can look nearly identical from species to species, especially in winter (non-breeding) plumage which becomes rather drab.  Check the bill’s shape first, as unique bills can immediately get you pointed in the right direction.  Is it long or short?  Is it straight or curved upward or downward?  How thick is the bill?  Be sure to also check the legs, the size of the head, or if the bird is compact in size or elongated.  If you can compare its size to another nearby shorebird, that can also assist with narrowing down the possibilities.

How does the bird forage?

Get to know how shorebirds forage as the feeding technique the bird utilizes may give you a clue to its ID.  For example, the Short-billed Dowitcher feeds by drilling vertically up and down, much like a sewing machine.  If you can observe the bird’s foraging technique, you can immediately narrow down the possible species.

The call might assist you with the shorebird’s identification.

Listen to it:  Can you hear it call?  Many shorebirds that visit the Caribbean have distinctive calls that can provide immediate identification.

Note the bird’s behavior.

Note the shorebird activities and its behavior:  In addition to its foraging style, note if it is social or solitary?  Is it with any other shorebird species and if so, which? How many birds of the same species do you see?

Note the bird’s habitat.

Many shorebirds have definite preferences for either saltwater or freshwater.  Others may prefer mudflats, salt ponds, or mangrove forests.  If you’re unsure of its identification, check to see which bird has a preference for the habitat you are viewing.

Is the bird likely to be seen when you are visiting Bonaire?

Note the timing:  Is it inside or outside of the normal window of opportunity to see this bird?  For example, is it a bird that is normally observed on Bonaire year-round, such as the Black-necked Stilt?  Or, like the Wilson’s Snipe, is it a migratory bird that is usually only found in the winter months?

Additional shorebird identification clues.

Once you think you have the answers based on the universal tips and tricks, you’ll find that other factors may complicate the shorebird identification process!

  • Light may be diffused, warm (early morning and late afternoon), cool (mid-day), behind clouds, or out in force.  Any of these conditions can play havoc with your shorebird identification.  The changing light may make the colors of plumage, bills, and feet and legs appear different!
  • The color of the legs is commonly used for shorebird identification.  However, for many wading shorebird species, the legs might be covered in mud, masking the true color.

Remember, if all else fails, and you are unable to identify your shorebird, try to take an image with your phone.  The Merlin Bird ID app will allow you to upload the image, and their database will provide you with its best guess as to the identification of your shorebird.

Take-away tip:  Use multiple clues to properly identify Bonaire’s shorebirds!
