Hairy-crested Antbird

The hairy-crested antbird is 14 to 15 cm (5.5 to 5.9 in) long and weighs 29 to 33 g (1.0 to 1.2 oz). Both sexes have a large pale bluish white ring of bare skin around the eye, and adults have a bushy crest. Adult males of the nominate subspecies R. m. melanosticta have an olive-tinged gray crest. Their nape, the sides of their neck, and their upperparts, wings, and tail are olive-brown. The wing feathers have rufous edges and the tail is blackish towards its tip. Their lores, face, and throat are black and the rest of their underparts dark olive-brown. Voice: One author described the hairy-crested antbird's song as a "slow series, starting with a few very high, sharp, fluted notes, then descending to a few drawn-out, grating notes". Others describe it as "a short series of wheezy, somewhat nasal whistled notes, e.g., 'wheeeyr, wheer-wheer-wheer-wheer' with descending effect". Its calls include a "harsh, vibrant 'chirr' abrupt 'chip' ".
