Green Manakin

The green manakin is 11 to 13 cm (4.3 to 5.1 in) long and weighs 10.6 to 18.3 g (0.37 to 0.65 oz). The sexes are alike. Adults of the nominate subspecies have a bright grass green head, upperparts, and central tail feathers. Their wings and outer tail feathers are dusky or brownish with green outer edges. Their throat, breast, flanks and undertail coverts are olive and their chin and central belly are pale yellowish. Voice: The green manakin is generally rather quiet. What is thought to be its song is described as "a high-pitched, thin whistle" and "a very high, rising tueee?". It also makes "a two-parted rattle, with the initial, shorter component a rough, lower buzz followed by a notably higher...longer, thinner rattle".
