About These Birds
Crested Bobwhite
A small New World quail (~130 g) of family Odontophoridae, males with a shaggy brown-white crest. Inhabits open savanna, grassland, scrubland, and agricultural areas in Central America and northern South America. Forages in coveys for seeds and invertebrates on the ground. Least Concern; one of the most widespread bobwhite species, tolerant of human-modified landscapes.
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.
