Manú 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. Their face and underparts are neutral gray with faint white streaks on their chin and throat. Both sexes have a pale sandy brown iris, a black maxilla, a darkish-mottled silvery gray mandible, and pale gray legs and feet.

The Mamu antbird has a disjunct distribution. By far the largest area encompasses southeastern Peru in southeastern Ucayali, northern Cuzco, and most of Madre de Dios departments; Pando and La Paz departments in northern Bolivia; and western Brazil's Acre state. Small isolated populations are also found further east in Amazonian Brazil. It almost exclusively inhabits stands of Guadua bamboo in partially shaded forest edges such as along watercourses and roads. In elevation it ranges between 250 and 1,350 m (800 and 4,400 ft).

The Manu antbird's diet has not been detailed but is known to be primarily insects. Pairs usually forage in the tops of bamboo stands and the canopy just above them, typically between about 4 and 15 m (15 and 50 ft) above the ground. They hop through the vegetation and usually take prey by gleaning while perched; they will occasionally hover-glean. They occasionally join mixed-species feeding flocks that pass through their territory.
