Appearance:

Unmistakable bird in most situations. Azure blue above, and orangy brown below. Very short tail, and large head with long and heavy bill. Often overlooked despite it's bright colours, due to small size and obscuring habitat. Often one only catches a glimpse of the light blue back, when it flies away close to the water surface in a whirring, darting motion.

Sound:

Most heard is the thin and penetrating contact call: A short "tzee", or disyllabic "tzee-tzu", with a ringing metallic quality. In excitement it is often alternated with ringing trills "tzeerrrrrrrrrr".

Appearance:

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.
