Bare-cheeked Babbler

Endemic and distinctive, medium-sized hummingbird found in the foothills of the Sierra Madre del Sur in Oaxaca. Favors humid evergreen forests and shade-coffee plantations. Mainly feeds at low to middle levels, darting quickly among flowers and flashing open its mostly white tail. Both sexes have a bright rusty panel in the wings, which appears as a blur when hovering. Male is brilliant green overall with blue cap. Female is pale gray below and has less white in the tail.

Thickset, short-winged, pot-bellied gull. Adult has dark gray back and wings, intense pink legs, and an especially large white “crescent” (white tertial edges) near the wingtips when perched. Breeding adult white-headed; nonbreeding birds have variably heavy brown streaking on the head and upper breast. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Often looks rather frosty by the first winter; starts to develop a gray back and whitish eye in its second year. Primarily an Asian species, found in coastal regions from Japan and South Korea to Russia. Regularly occurs in western Alaska, but very rare elsewhere in North America.

Graceful songbird of well-shaded forests, particularly stream gullies; often in more open habitat in migration. Stunning breeding male purplish-black above and white below, with a short crest, neon-blue eyerings, and long black tail streamers. Female and non-breeding male have dark gray head and chest, paler eyering, shorter crest, and chestnut-brown wings and tail, without streamers. Compare with female and non-breeding male Amur and Blyth’s paradise-flycatchers, with which Black overlaps on its Southeast Asian wintering grounds. Note Black’s contiguous dark gray throat and chest (Amur has a more sharply-demarcated black throat and gray chest), dull darkish wings (Blyth’s has brighter rufous wings), and fairly clean demarcation between gray breast and white belly (Blyth’s has a more gradual fade). Song a run-on series of coarse whistles; call a rough, nasal “bee.”
