About These Birds
Buffy-crowned Wood-partridge
A medium-sized New World quail (~370 g) of family Odontophoridae, with a buffy-white supercilium and rufous-brown plumage. Inhabits montane cloud forests and humid highland forests from Mexico through Central America to Panama. Forages on the ground for seeds, berries, and invertebrates. Least Concern; commonly heard but seldom seen due to dense forest cover and secretive behavior.
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.
