Oriole cul-noir Icterus wagleri

Attractive oriole of the interior and highlands; some migrate in winter to Pacific coast lowlands. Favors scrubby woodlands and semiopen areas with tall hedges of flowering trees; also flowering coconut plantations on the Pacific coast. Usually in pairs; found as often apart from other orioles as mixed with them. Sexes alike: yellow breast has a distinctive, burnished orange tone. Upperparts appear wholly black when rump is covered by wings. Black vent area diagnostic on adult. Immature variable: note lack of wingbars, orange tones to yellow plumage, and rather long, straight bill.
