Manicoré Warbling-Antbird

The Manicore warbling antbird is about 11 cm (4.3 in) long and weighs about 12.5 g (0.44 oz). Adult males have a black crown with a white central streak and a white supercilium on an otherwise black and white speckled face. Their mantle and back are blackish with whitish and olive-brown edges to the feathers. They have a white patch between their olive-brown scapulars. Their lower back is dark yellowish brown that becomes rustier towards the rump. Their flight feathers are brown with rufous edges and their wing coverts olive-brown to black with white tips. Their tail is dark yellowish brown with buffy white tips and rufous edges to the feathers. Their throat is whitish with faint darker mottling. Their breast and upper belly are darker than the throat, their belly's center is whitish, their sides and flanks are orangey to rusty with some blackish markings, and their undertail coverts are unmarked orangey to rusty. Females have the same pattern but different colors than males, generally replacing black with olive-brown.

The Manicore warbling antbird is found in a limited area of central Amazonian Brazil where southeastern Amazonas, northern Rondônia, and northwestern Mato Grosso meet. It occurs along the right bank of the Rio Madeira, between the rios Aripuanã and Ji-Paraná, and along the left bank of the Rio Roosevelt. The species inhabits terra firme forest. It favors the understorey of the forest edges and within the forest along watercourses and at gaps caused by fallen trees.

The Manicore warbling antbird's diet and foraging behavior are not known in detail, but it does feed on insects. Pairs forage together and sometimes join mixed-species feeding flocks that pass through their territory. Its diet and other behavior are assumed to be similar to those of H. cantator.
