A specialist hunter of fiddler crabs, the Wilson's Plover is a heavy-billed shorebird of sandy beaches in the southern United States and in coastal South America. It blends in well with its shell-strewn beach habitat, and its plaintive call is often the first clue to its presence. These sandy brown birds look like a small Killdeer or a larger, bigger-billed Semipalmated Plover, with a single, broad breast band. Wilson’s Plovers are vulnerable to beach disturbance and development, and are on the Yellow Watch List for species with restricted ranges.
