About These Birds
Spot-winged Wood-quail
A medium-sized New World quail (~425 g) of family Odontophoridae, with spotted brown plumage and an orange eye ring. Inhabits Atlantic Forest, cerrado woodland, and interior humid forests of eastern South America in Brazil, Paraguay, and Argentina. Forages on the forest floor for seeds and invertebrates. Least Concern; dependent on forest cover but broadly distributed in southeastern Brazil.
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.
