What the Black-whiskered Vireo sounds like
ID tip
The black-whiskered vireo is 15 to 16.5 cm (5.9 to 6.5 in) long. The nominate subspecies V. a. altiloquus weighs an average of 18 g (0.63 oz). The sexes have the same plumage. Adults of the nominate subspecies have a bluish gray forehead and crown with a buff-olive tinge, a buffy whitish supercilium from the bill past the eye, a wide dusky stripe through the eye, and the eponymous black "whisker" on the sides of the throat. Their nape and upperparts are olive-green. Voice: Migratory black-whiskered vireos sing during the breeding season and are silent on the wintering grounds. Nonmigratory populations sing year-round but more frequently during the breeding season. In the West Indies the black-whiskered vireo sings monotonously throughout the day, "hort, melodious 2- to 3-syllable phrases, each different, separated by pauses".
