Appearance:

Small, stout, unmistakable raptor with pale grey plumage. Strikingly broad wings and short tail. Large, round, owl-like head with black "mascara" and short neck. Underside of wing-tips, and upper median and lesser coverts black. Immature birds often with rusty underparts and white fringes to flight feathers and scapulars. Glides with wings raised high like a harrier. Frequent and skilfull hovering.

Sound:

Not very vocal. A soft "Pjuu-harrr". Starting as a mellow, ascending whistle and ending with a harsh screech. Also uttered without the harsh ending, or only a Barn Owl-like screech. Other sounds: rapid series of soft "kekekekekekekekeke" and short whistles.

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".
