About These Birds
Black-fronted Wood-quail
A medium-sized New World quail (~290 g) of family Odontophoridae, with a distinctive black forehead. Inhabits montane and foothill forests in the Andes and Sierra Nevada de Santa Marta of Colombia and Venezuela at 500–2,000 m elevation. Forages on the forest floor in pairs for seeds and invertebrates. Least Concern; found in Andean forests with populations considered relatively stable.
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.
