About These Birds
Stripe-faced Wood-quail
A medium-sized New World quail (~315 g) of family Odontophoridae, with bold facial striping. Inhabits humid montane forests on the eastern Andean slopes of Peru and Bolivia at 1,000–2,500 m elevation. Forages on the forest floor in pairs or small groups for seeds and invertebrates. Least Concern; restricted to Andean cloud forest but broadly distributed with stable populations in protected areas.
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.
