Appearance:

Usually recognizable by size alone. Distinctly smaller than any congener. Pale wing-panel formed by inner coverts is striking in all plumages, especially in flight. Male with contrasting black and white/buff plumage. Female with dark, but pale fringed back and streaked throat. Immature with streaked, bittern-like plumage, and wing-panel is brown-spotted. Skulky behaviour, and most active at dusk or after dark. Mostly seen in flight when crossing open water. Flight action rapid and clipping, and landing is preceded by short glide.

Sound:

Mostly silent except in breeding season. Song is a series of short, deep, frog-like "gorrk", repeated every 2 seconds. Tone is muffled and hollow, but far-carrying. Flight-call a sharp "ki-ke-ke" or a nasal "ke".

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.
