Cory's Shearwater (Calonectris diomedea)
Bluethroat (Luscinia svecica)
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.

CCMale unmistakable. Blue throat with rufous red or white center, white supercilium and rufous base of outer tail feathers. Female lacking, or having just a partially blue throat. Female and juveniles could be confused with Redstart because of the rufous tail, but note its dark, bold trailing edge and center. An elegant and fairly long-legged chat that often flicks its wings and cocks its tail.
Sound:Song: Structure slightly similar to Nightingale, but tone much thinner and less full-bodied. A good impersonator and various imitations are interwoven among metallic, ringing sounds to form a complex, intriguing song. Call: "pju-check". Double syllable starting as a descending whistle, and ending on a short "check".
