Appearance:

Like a Great Tit-sized Willow Tit. Dark bib very large much bigger. The hood is also extended, and covers more of the head than in Willow Tit, making the white cheeks very narrow and wedge-shaped. Bulky build, with broad head and strong bill. Told from Siberian Tit by complete lack of buff tones to underparts and flanks. Less acrobatic than other tits, and bill powerful enough to tear seeds apart like a finch.

Sound:

Structurally resembling other tits call and song. Usually recognised by its distinct timbre. Its peculiar, rapidly modulated voice sometimes resembles a tit with added electronic effects. Call: a characteristic "tz tz chrrt", resembling the alarm call of House-sparrow.

Appearance:

A large shearwater with pale upperparts and heavy, yellowish bill. Large grey head. The grey neck forms a diagnostic, contrasting line from wing base to base of bill (most other shearwaters have white neck-sides). Armpits usually pure white. Underside of wings white, framed by black flight feathers. Flight action calm and distinct. Long glides alternates with 3-4 slow wingbeats. Wingtips always bent downwards, and wings slightly angled back. Often soars. Differs from Fulmar in dark tail, grey head, long, narrow wings and longer bill. The two subspecies C. diomedea and C. borealis, are somtimes treated as different species. Field identification of these usually impossible, and requires ideal conditions. Hand of borealis is darker due to no white fringes to primaries. In diomedea the white in the coverts extends in a white wedge into the hand, through the base of the primaries.

Sound:

Very vocal at breeding ground. Calls with a very nasal, comical, mewing "ke-kooeee", ending with falling pitch, like a releasing sigh or moan. Sometimes reltively pure, other times very hoarse and raucous.
