Cetti's Warbler (Cettia cetti)
Cory's Shearwater (Calonectris diomedea)
Small, warm buff warbler with skulking behaviour, but conspicuous song. Similar in size to Reed Warbler, but with short, rounded wings and rounded tail. Build fairly compact, but bill thin and slender. Supercilium thin and dull. Cheeks and underparts greyish white, lacking the purer white belly of confusion species. Pale eye-ring. Under tail-coverts usually brown with pale fringes. Often flicks tail or holds it raised. Usually hides among undergrowth, and shows itself only when moving from one shrub to another.
Sound:Contact call a short, metallic, ascending "vitt". Often given in rapid series. Song diagnostic, and readily given throughout the year. Phrases last from 2 - 5 seconds, consisting of a few loud, clear and rapid glissandi, given in approximately same register. E.g. "cetti cetti cetti", usually with a few introductory notes, and some variation to the phrase. Overall a very explosive, and with a staccato rhythm.

CCA 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.
