About These Birds
Northern Bobwhite
A small New World quail (~195 g) of family Odontophoridae, males with a white supercilium and throat on brown-patterned plumage. Found in open woodlands, grasslands, and agricultural edges across eastern North America and Mexico. Forages in coveys for seeds and insects. Near Threatened; once abundant but suffering severe range-wide declines from agricultural intensification, habitat loss, and pesticide use.
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.
