Coleto

A little-known medium-sized, short-tailed swift found over forest, usually at higher elevations. Mainly black with obvious white throat and underwing patches. Wing shape is unusual, with a “cut-out” next to the body and pointed wing tips curved backward. Tail square, with spines that are difficult to see. Distinguished from other swifts in its range by the white marks under the wings. Voice unknown.

A tiny curve-billed myzomela. Male is red-faced with olive-green upperparts and buffy cream underparts. Found in montane forest above 200 meters of elevation, but more commonly above 500 meters of elevation. Male unlikely to be misidentified. Female diagnosed by mostly brown plumage and reddish head, unlike the much darker blackish Bismarck Black Myzomela.

A large, sturdy gull of East Asia. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Extremely variable plumage can make identification tricky. Occurs inland and along the coast, frequenting river mouths, harbors, beaches, lakes, and ponds. Often forms flocks with other gulls. Back color of adults generally a shade darker than that of American Herring Gull. Very similar to Mongolian Gull, and separation is tricky, but has a larger head and bill; adults also generally have pinker legs.
