The Cinnamon-vented Piha, a southeast Brazilian endemic, largely replaces the marginally smaller Screaming Piha (Lipaugus vociferans) in this region. Where the two species do meet, generally the Cinnamon-vented Piha occurs in foothill forests, whereas the Screaming Piha inhabits the remaining parcels of true lowland forest. In plumage, the present species’ plumage is overall more cinnamon-brown, rather than gray, and as its English name suggests, this colour is at its brightest on the undertail coverts. The Cinnamon-vented Piha occurs from the understory to the midstory and in the subcanopy of humid Atlantic Forest, as well as more rarely in drier forests. Based on the detailed observations of Edwin Willis and Yoshika Oniki at two nests of this species, our knowledge of its breeding biology is surprisingly unparalleled amongst the genus Lipaugus. These authors speculated that the one-parent nesting system, which appears to be adopted by all members of the genus for which nests have been found to date, is an adaptation to nesting in the midstory and their feeding habits.
