Firecrest (Regulus ignicapilla)
Cory's Shearwater (Calonectris diomedea)
Distinct head markings, with black eye-stripe contrasting with broad, white supercilium. Top of head yellow (female), or orange (male), framed by black crown stripes. Characteristic orange shoulder patch, lacking in all confusion species. Immature is distinguished by present supercilium, other head markings absent.
Sound:Call: a thin "tsi tsi tsi" similar to Goldcrest, but not so sharp. Song: Similar in timbre to Goldcrest, but much more monotonous. A slow crescendo of short "tze" sounds in a phrase rising slightly in pitch, without the repeated arpeggiated movements of goldcrest.

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.
At breeding ground (C. d. borealis):
