Inhabits humid forest on both slopes of the Andes in western Ecuador and Colombia below 1,500 m elevation. Forages on the forest floor for seeds, invertebrates, and fallen fruits. Least Concern; found in Chocó and western Andean forests, relatively tolerant of some disturbance.
Nahan's Partridge
A small partridge (~280 g) of family Odontophoridae, dark reddish-brown with black barring. Endemic to lowland primary rainforest in Uganda and the Democratic Republic of Congo. Highly terrestrial, foraging on the forest floor for seeds, berries, and invertebrates. Vulnerable; requires intact primary forest and is threatened by widespread logging and agricultural conversion in Central Africa.
