About These Birds
Gambel's Quail
A small New World quail (~175 g) of family Odontophoridae, males with a forward-drooping plume, chestnut crown, and black belly patch. Inhabits desert scrub, riparian woodland, and cactus-brush habitat in the southwestern United States and northwestern Mexico. Forages in coveys for seeds and plant shoots, dependent on succulent vegetation for water. Least Concern; thrives in arid desert environments.
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.
