The '''Belcher's Gull'(Larus belcheri''), also known as the or Band-tailed Gull, is a gull found along the Pacific coast of South America. It formerly included the very similar Olrog's Gull as a subspecies. It is a medium-sized gull with a blackish mantle, white head and underparts, a black band in the otherwise white tail, and a yellow bill with a red and black tip. Non-breeding adults have a blackish head and a white eye-ring.
The name of this bird commemorates the British explorer Sir Edward Belcher.
