Small and agile gull with all black wing-tips, black legs (adults) and yellow bill. Area close to wing-tips much paler than rest of wings, and often visible at surprisingly long range (more so than the black tips). Adult winter with grey neck and black half-collar. Juveniles with black zig-zag pattern to wings, resembling pattern seen in Little Gull, Ross's Gull and Sabine's Gull. Differs from those in; no dark bar on secondaries, underparts of wing white, back grey, black on primaries reaches wing-tip. Flight action different from larger gulls; fast, stiff wing-beats and elegant maneuvering even in strong winds.
Sound:Highly vocal at breeding ground. A mewing "kitti-wake", with the pitch rising on the second drawn out syllable, and then falling. Generally silent elsewhere, except when squabbling over food.
