Appearance:

Rather large and heavily built Sylvia with dark hood and pale iris (in adults). Lacks red orbital ring of Sardinian Warbler. Very similar to Western Orphean Warbler (S. hortensis), but usually distinguished from that geographically by different breeding and wintering range, and also by appearance in typical birds (in addition to song). The following field marks differs from S. hortensis; dark centres to under tail coverts and whiter underparts with very little buff tones (slightly buff flanks in some). Other more variable traits are; dark hood more distinctly bordered in neck, colder grey upperparts and longer, more curved bill. Vagrant immature birds outside of normal distribution may be impossible to tell from S. hortensis. Apart from size, it differs from Lesser Whitethroat by; stronger bill, lack of incomplete white eye-ring, darker upper tail and above mentioned under tail coverts.

Sound:

Contact call a short "check", sometimes in series. When agitated a nasal, rattling "trrrr-trrrr-trrrr". Both calls very similar to S. hortensis. Song distinct, but with same quality of fluting sounds as in S. hortensis, recalling that of Blue Rock Thrush in timbre. Phrases often long and much more varied and impressive, with frequent mimicry. May be mistaken for Nightingale, but incorporates more dry trills, is slower, harder and lacks the diagnostic series of plaintive notes (may mimic it!).

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.
