Any of about seven species (genus Haematopus , family Haematopodidae) of stout-bodied shorebirds inhabiting temperate and tropical seacoasts and inland waters in Europe, Asia, Africa, the Western Hemisphere, and Australia.
Oystercatchers are 16–20 in. (40–50 cm) long, with thick pinkish legs; long pointed wings; and a long, flattened, wedge-shaped, orange-red bill. Their plumage varies from black-and-white, including a bold white wing patch, to entirely black. They attack mollusks as the tide ebbs, when the shells are exposed and still partially open.
