About These Birds
Venezuelan Wood-quail
A medium-sized New World quail (~340 g) of family Odontophoridae, with brownish-rufous plumage. Endemic to the coastal mountain range of northern Venezuela. Inhabits humid montane and cloud forests at moderate elevations. Forages on the forest floor for seeds and invertebrates. Near Threatened due to restricted range and ongoing deforestation in the Venezuelan coastal cordillera.
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.
