Cattle Egret (Bubulcus ibis)
Cory's Shearwater (Calonectris diomedea)
Small, stocky, white heron with short bill and neck. Heavy jowl. Plumage all white, except in breeding birds which show varying amount of buff on back, crown and chest. Bill usually yellow, but turns orange-red in breeding birds, and is dark in immatures. Legs pale greyish green, but darker in young birds. May be confused with both Little Egret and Squacco Heron in flight. Differs from Little Egret in leg color and shorter, thicker neck and bill. Told from Squacco Heron by unstreaked body/head, and smaller bill. Generally leaves a less elegant impression than other small herons.
Sound:Usually silent away from breeding ground. In the colonies a chorus of various coarse sounds can be heard. Most distinct is a disyllabic "rick-rack". Other sounds includes short, guttural utterings, or drawn, harsh shrieks.

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.
