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:

An almost featureless, large warbler with greyish brown upperparts and buff underparts. Lack of distinct characters is a character! Most distinct character is probably the faint, slate grey half-collar. Vent has no markings, eye is dark and bill is relatively short. Body quite plump, and facial expression gentle and mild. Usually stays hidden in foliage. Lacks nervous behaviour of other Sylvia, and does not normally flick its tail and wings.

Sound:

Song: a full bodied, flowing, melodious stream of notes, distinguished by its almost constant, warbled quality and lack of clear whistling notes (see Blackcap). Tempo is fairly even. Beware confusion possibility with occasional subsong of Blackcap that never reaches the whistling part! Call a nasal "che". Alarm call a hard "check", and a hoarse "tcherr".
