Scott's Oriole
Icterus parisorum
Scott's oriole is about 23 cm (9.1 in) long with a wingspan of 32 cm (13 in); it weighs 32 to 41 g (1.1 to 1.4 oz). Adult males in breeding plumage have a black head, back, scapulars, throat, and breast. Their rump, uppertail coverts, and underparts below the breast are lemon yellow. Their wings are black with pale yellow lesser and median coverts that show as an epaulet. The wing's greater coverts have white tips that show as a wing bar. Their tail feathers are mostly black with yellow bases and white tips, both of which are larger towards the outer feathers. Voice: The song of Scott's oriole is a "series of varied, short notes...; pure whistles (notes with a single dominant frequency) interspersed with notes that are rapidly modulated in frequency, some ascending, some descending, and some with both ascending and descending portions". Both sexes sing but female song is usually not as complex as male song.
