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.

Appearance:

Slightly more compact than Yellowhammer, with shorter wings and heavier bill. In all plumages note; olive to grey rump, greyish lesser coverts and finely streaked flanks. Male unmistakable with black throat and eye-stripe. Female and immature lacks black throat, but have more contrasting eye- and moustache-stripe than Yellowhammer.

Sound:

Song variable, but can generally be described as a Yellowhammer phrase with no ending, or an Arctic Warbler with bunting timbre. Tempo also variable, but rhythm always even. Alarm call a thin "tseeep", similar to Rock Bunting, but more drawn out.
