Wire-tailed Manakin

The wire-tailed manakin is sexually dimorphic. The species is 11 to 12 cm (4.3 to 4.7 in) long exclusive of the eponymous tail filaments. Male's filaments add about 4 cm (1.6 in) to its length and female's about 2.5 cm (1.0 in). The species weighs an average of about 14 g (0.49 oz). Adult males of the nominate subspecies have a yellow forecrown, face, and throat; the rest of their crown, nape, and sides of the neck are bright red. The rest of their upperparts, wings, and tail are black. Their entire underparts are yellow. They have a white or whitish iris.
