Habitat

Found in Bolivia, Brazil, and Peru, the species primarily inhabits the edges, gaps, and watercourses in evergreen and mature secondary forest. It favours stands of bamboo and typically occurs below 300 m (1,000 ft) in elevation, though it reaches 1,600 m (5,200 ft) in southeastern Peru.

Diet

The diet consists primarily of insects and spiders. Foraging behaviour is not detailed but is assumed to be similar to that of H. cantator, with the specific exception that this species feeds more often at clusters of dead leaves.
