MacGillivray's Warbler

Nondescript warbler, generally olive-colored overall, but different populations vary from grayer to brighter yellow. Overall very plain and unmarked, but note short darkish line through eye and thin pale eye arcs. Forages for insects in scrubby areas, woodland edge, and thickets. Namesake orange crown is very difficult to see, and usually only a faint wash at best. More common in western North America, from Alaska to Mexico, where populations are brighter yellow-green. Birds in eastern North America are scarcer and drabber, often with a more contrasting grayish head. Bright yellow undertail coverts help separate Orange-crowned from the similarly drab Tennessee Warbler.

Secretive, handsome endemic pheasant of Taiwan's mountains. Male slaty blue from nape to flanks, with contrasting white upper back, brown mantle, and dark gray wings; female mostly rich brown with pale markings above. Both sexes have red facial skin, more extensive in male. Forages quietly in pairs in the forest understory, occasionally along forest edge on trails or roads. Both sexes give subtle clucking calls and a high-pitched squeaky alarm call. Male has white in tail and back, unlike Mikado Pheasant; female distinguished by richer plumage tones, broader tail, pale bill, reddish legs, and unmarked underparts.

An unusual duck of alpine lakes and mountain streams. Very distinctive elongated shape with yellow bill, dark head, strong barring on the body and a pointy tail which is cocked when startled. In flight, it has a green panel in the wing bordered with white. It swims with a distinctive head-bobbing motion and feeds by dabbling and diving. It is a strong swimmer and can also do agile leaps onto rocks. Usually silent, but occasional gives a quack or series of “whip-whip-whip” notes.
