Cory's Shearwater (Calonectris diomedea)
Redshank (Tringa totanus)
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.

CCAdults differ from most other waders by bright red legs. Large white rectangular patches on secondaries conspicuous in flight in all plumages. Spotted redshanks in winter- or juvenile plumage lacks white wing bars, are more elegant with a more slender bill, and shows a stronger dark eyestripe and white supercilium. Juvenile Redshanks are unevenly, and sparsely spotted below from the legs to the vent, as opposed to the barring of juvenile Spotted Redshanks. Leg colour in juveniles often dull yellowish. Flanks evenly spotted. Winter plumage with brownish upperparts.
Sound:Generally a noisy and loud bird, especially at breeding ground. Most heard is a characteristic "tew-hoo", or "tew-hoo-hoo" with first syllable accentuated. No gap between the syllables like Greenshank, and usually with a marked falling pitch. Song similar to Wood Sandpiper, but with three accented notes in each cycle, not two.
