Chilean Flamingo

Widespread wagtail, favoring wet meadows, marshland, grassy and muddy lakeshores. Occurs in fields and often near livestock during migration. Like other wagtails, walks on ground and pumps its long, white-sided tail up and down. Plumage highly variable, but breeding male wholly bright yellow below, with greenish back. Male head pattern varies regionally: in U.K. has greenish head with yellow eyebrow; in northern Europe head slaty gray overall; in central and southwest Europe head blue-gray with white eyebrow; striking white-headed birds in Mongolia and northwestern China. Individuals of several subspecies may winter together. Female and nonbreeding plumages drabber and paler, with ghosting of male patterns. Songs and calls vary between subspecies, but most give some form of buzzy “dzeerdzeer” or downslurrd “tzree.”

A pretty and distinctive bird that always lacks the long tail streamers possessed by some paradise-flycatchers. Note the rufous back and tail and the gray underparts. Males and females differ slightly: males have a black cap and a blue eye-ring, whereas females have a dark-gray cap without a distinctive eye-ring. Fairly common on Reunion in all types of humid forest. Rare on Mauritius in remnant rainforest patches. Calls include a tearing “sree-sreeet” and an agitated twittering. The song is a long musical series of “twee” notes.

Rather large, blue-and-gray jay of highland pine and pine-oak forest endemic to highlands of central Mexico; occurs in transvolcanic belt from Volcánes de Colima in the west to Volcán Orizaba in the east. Typically travels in wide-ranging flocks of 5–25 birds, mainly at middle to upper levels in trees. Appreciably larger and broader-winged than Woodhouse's Scrub-Jays, with plainer plumage (lacks dark mask, whitish eyebrow, and partial dark collar of Woodhouse's Scrub-Jay). Noisy calls carry well.
