A medium-sized New World quail (~295 g) of family Odontophoridae, with contrasting black breast and white facial markings. Inhabits humid lowland and foothill forests in Costa Rica and Panama. Forages secretively on the forest floor in pairs or small groups for seeds and invertebrates. Least Concern; found in intact forest of Central America's Pacific and Caribbean slopes.
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.
