About These Birds
Mountain Quail
A medium-sized New World quail (~240 g) of family Odontophoridae, with a long straight head plume and chestnut flanks barred in white. Inhabits chaparral, brushy mountain slopes, and pine-oak forest in the Pacific mountain ranges of western North America. Forages for seeds, bulbs, and berries. Least Concern; the largest North American quail species, exhibiting altitudinal migration.
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.
