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:

Plumage green, grey and yellow. Note bright, yellow base of primaries and sides of tail in all ages and plumages. Deep and heavy conical bill. Tail forked and quite short. Plump build. Female more grey than male, with back diffusely streaked in brown and underparts greyish. Juveniles similar to females, with even more drab colours and heavier streaking (also on underparts). Strongly undulated flight. Often appears somewhat clumsy when trying to perch on feeders etc.

Sound:

Song composed of various sequences of linked sounds, repeated in a vibrating manner; "trrrrrrrrr", "chechechecheche". Sometimes resembles Brambling when making the wheezy "rrrrrrrrr" sound, but differs in being harsher and by "pulling" the pitch downwards (or sometimes upwards) at the end. Contact call a fairly resonant "chep-chep", resembling Redpoll, but less nasal and with a fuller tone. Also a sharp, drawn, ascending "kooeee", (perhaps not obviously recognized as a finch).
