About These Birds
Black-throated Bobwhite
A small New World quail (~130 g) of family Odontophoridae, with a distinctive black throat in males. Inhabits open pine savannas, grasslands, and agricultural edges from southern Mexico through the Yucatán Peninsula to Nicaragua. Forages on the ground for seeds and invertebrates in small coveys. Least Concern; adapted to fire-maintained savanna habitats of the Caribbean lowlands.
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.
