Appearance:

Chocolate-brown hood in adult plumage (seemingly black at a distance), but head only with dark markings in winter and juvenile plumages. Underparts of inner primaries dark grey. First few primaries white with black tip, both on upper side of wing and under. Last character conspicuous in all plumages, but slightly less obvious in juveniles due to larger dark area of wing-tip. Slender-billed Gull and Bonaparte's Gull show similar white first primaries, but differs in long and slender head profile and white underparts of hand respectively.

Sound:

Quite vocal, especially at breeding ground. Distinct, harsh calls. A rasping "kreearr", and shorter, sharp warning calls; "kek".

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"
