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:

Summer plumage: Warm, rufous brown below like Knot, but much smaller. Bill curved and much longer, and appearance more long-legged. Winter and juvenile plumage grey above and pale below. Differs from Dunlin in slightly longer legs and bill, more pronounced supercilium, no black patches on belly (some rufous summer feathers may show when moulting) and more upright stance. Juveniles with buff-pinkish tone to breast, and scaly upperparts. Always distinct in all plumages when flying, due to bright white and crescent-shaped rump-patch.

Sound:

Flight call a soft, ringing and rolling "krrrrrt, with variations. Lacks the hoarse, nasal quality of similar call by Dunlin.
