Appearance:

Very similar to Marsh Tit, but cheeks whiter, head bigger, and upperparts greyer with white wing-panel. Black bib wider and bigger than in Marsh Tit. Lacks white spot at base of upper mandible. Willow Tits in Great Britain are warmer brown and are more difficult to separate from Marsh Tit.

Sound:

Call: Most characteristic call a frequently uttered, nasal "ti ti chaa chaa chaa". First notes high pitched and the following lower, coarse, nasal and drawn. Sometimes uttered without the introductory high pitched notes. Song: One or two soft, clear, melancholic notes repeated in a slow, even rhythm. At first rising slightly in pitch, then gradually falling. In some areas song is evenly pitched. Other sounds: high pitced "zi zi" similar to other tits.

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.
