The Black-capped Becard is a fairly common resident of humid lowland forests of South America. Two subspecies of this becard are geographically isolated, with one occurring throughout most of Amazonia and the other in eastern Brazil. The male has a glossy black crown and back, and gray lores, sides of the neck, and underparts. It is similar to the White-winged Becard (Pachyramphus polychopterus), with which it overlaps broadly, but Black-capped has paler underparts and a light spot on the lores. Females have a chestnut crown, and yellowish underparts; the upperparts primarily are olive, with cinnamon scapulars and wingbars; this plumage is similar to that of the female White-winged Becard, but White-winged has a brownish back, and the crown is duller, less chestnut. Found in the forest canopy, Black-capped Becards often join mixed-species flocks where they actively feed on insects and fruit, sallying and hovering to glean food. Little is known of their breeding habits. Throughout most of its range the Black-capped Becard is unlikely to be threatened, although the isolated population of eastern Brazil may be at greater risk.
