About These Birds
Ferruginous Partridge
A small partridge (~210 g) of family Phasianidae, with rich ferruginous (rust-red) plumage and spotted black-and-white markings. Inhabits lowland and foothill rainforests in Malaysia, Sumatra, and Borneo. Secretive, foraging on the forest floor for seeds and invertebrates. Near Threatened; associated with primary and tall secondary forest, declining with ongoing logging and land conversion.
Black Partridge
A small sexually dimorphic partridge (~280 g) of family Phasianidae, males entirely black and females rufous-brown. Endemic to lowland rainforests of the Thai-Malay Peninsula, Sumatra, and Borneo. Highly secretive, foraging on the forest floor for seeds and invertebrates in dense undergrowth. Vulnerable; declining with rapid lowland deforestation and conversion to palm oil plantations.
