The elegant Roseate Tern, with its long, white tail streamers and rapid flight, is seen along the Falmouth coast throughout the summer. It nests on islands in Buzzards Bay within colonies of Common Terns, from which it derives protection from intruders. The Roseate Tern is a plunge-diver that feeds on bait fish. Due to recent population declines, the Roseate is now considered an endangered species at both the state and federal levels. Breeding adults have pale gray upperparts, white underparts, a black cap, orange legs and feet, and a black bill. The tail is mostly white, and is deeply forked.
