Inhabits Andean cloud forests and forest edges from Venezuela south to Bolivia at elevations of 1,200–3,500 m. Feeds on fruits, seeds, and invertebrates. Least Concern; widespread in montane Andes and one of the more commonly encountered Penelope guans.
Chestnut-bellied Guan
A large cracid (~1.2 kg) of family Cracidae, with rich chestnut-colored belly and red throat wattle. Endemic to the cerrado and transitional forests of central Brazil. Inhabits gallery forests, cerrado woodland, and humid forest patches. Feeds on fruits and seeds. Vulnerable due to massive cerrado deforestation; restricted to increasingly fragmented habitats in the Brazilian interior.
