Collared Dove (Streptopelia decaocto)
Cory's Shearwater (Calonectris diomedea)
A small, long-winged and pale buff-grey pigeon, with characteristic black half-collar stretching from the hind-neck to the sides. Most likely to be confused with Turtle Dove, but upperparts of tail lacks strong contrasts, undersides of wings are whitish and lower belly buff (not white). Juveniles lacks the black neck-collar.
Sound:Song a characteristic, rhythmic cooing, consisting of three syllables with emphasis on the second. The third lower pitched than the rest. Can be rendered as "su-do-ku" (or "deca-oc-to", latin name derived from song). Excitement-call a nasal "wrrraa".

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):
