The mostly widely distributed species of wood-quail. Resident in humid forest lowlands from Costa Rica south to northern Colombia, east to the Guianas, and south to central Bolivia and south central Brazil.
Occurs below 900 m in Costa Rica (Stiles and Skutch 1989), although in Panama occurs up to 1500 m (Ridgely and Gwynne 1989). In Andean countries, the reported upper elevational limits are 1200 m in Colombia (Hilty and Brown 1986); to 1500 m in northern Venezuela, but to 1800 in Venezuela south of the Orinoco (Hilty 2003); and to 900 m in Ecuador (Ridgely and Greenfield 2001).
Distribution outside the Americas
Endemic to the Americas.
Primarily occurs in humid lowland forest; also may occupy old second-growth forests or patches of forest interspersed among coffee plantations (Hilty and Brown 1986, Hilty 2003).
Inhabits the greater part of its historical range, but there are local range contractions, primarily due to deforestation or other human activities. Formerly occurred in extreme western Chiriquí, Panama, for example, but has not been reported from there since 1901 (Wetmore 1965). Also formerly occurred on Barro Colorado Island, Panama, but the last record there as in 1953 (Wetmore 1965, Willis and Eisenmann 1979).
