Manu Antbird

The Manu antbird is 14 to 15.5 cm (5.5 to 6.1 in) long and weighs 16 to 20 g (0.56 to 0.71 oz). Adult males are mostly very dark gray, with paler gray on their face, flanks, and undertail coverts. They have a mostly hidden white patch between their scapulars, white tips on their wing coverts, and white tips on their tail feathers. Females have an olive-brown crown and back with a hidden white interscapular patch. Their wing coverts are dusky brown to black with white tips. Their tail is dark gray-brown with white crescents near the feather tips. Voice: The male Manu antbird's song is "a slow series of deep, rich note pairs: pook-CHA pook-CHA pook-CHA pook-CHA". Females respond with a series of deep "kl'du" notes; both members of a pair may also sing this in duet. The species' call is "a descending chortling series of musical, hooting whistles "t'hee'hoo'lululululu".
