Oystercatchers are shorebirds known for their striking black and white plumage and long, bright orange bills. They are commonly found along coastlines and estuaries, where they feed primarily on mollusks, such as oysters and clams. Their strong bills allow them to pry open shells to access the soft flesh inside. These birds are social and often seen in groups, especially during the breeding season. Oystercatchers typically nest on sandy beaches or rocky shores, laying a few eggs in shallow scrapes. They are known for their loud, distinctive calls, which help maintain communication within their flocks.
