About These Birds
Gorgeted Wood-quail
A medium-sized New World quail (~300 g) of family Odontophoridae, with an ornate patterned gorget on the throat. Endemic to the eastern Andes of Colombia in a restricted area of Cundinamarca and Boyacá departments. Inhabits humid montane forests at 1,700–2,700 m elevation. Vulnerable; extremely small range, heavily deforested habitat, and poorly known population size.
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.
