Appearance:

Bulky raptor with long tail and short, rounded wings. Small males may be difficult to separate from large Sparrowhawk females. Upperparts grey-brown, and underparts pale and barred or speckled. Male and female quite similar, but female larger. Juveniles browner than adults, with heavily speckled underparts. Supercilium prominent in both sexes. Bulkier belly and broader at base of tail than Sparrowhawk. Deep chest. Longer wings and longer secondaries gives more of a S-shape to trailing edge of wings. Slightly rounded tail-corners visible when soaring. Flight alternates series of wingbeats with short glides without loosing height.

Sound:

Series of short "ke-ke-ke-ke-ke". More resonant, both sharper and deeper pitched than similar call of Sparrowhawk, and much slower. Also a wailing "peeeaaaaw"

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.
