Striolated Manakin

The striolated manakin is 9 to 10.3 cm (3.5 to 4.1 in) long and weighs 6.4 to 12.5 g (0.23 to 0.44 oz). The species is sexually dimorphic. Adult males of the nominate subspecies M. s. striolatus have a bright red forehead, crown, and nape. Their face, upperparts, and tail are bright olive-green. Their wings are mostly a grayer olive-green than the upperparts and have white tips on the tertials and white inner webs on the other flight feathers. Their chin and throat are buff or whitish. The rest of their underparts are whitish with bold red stripes on the breast, belly, and flanks. Voice: The male striolated manakin's "advertising call" varies among the subspecies but is "always somewhat insect-like". In Ecuador its song is described as a repeated "soft, clear, whistled who-cheéuw". In Peru it is described as "a high, sneezy cli-CHEW!".
