About These Birds
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.
Crested Partridge
A small partridge (~250 g) of family Phasianidae, males with vivid crimson crest and iridescent green plumage. Found in lowland tropical rainforests of Southeast Asia including Thailand, Malaysia, Sumatra, and Borneo. Forages on the forest floor for fallen seeds, fruits, and invertebrates. Vulnerable; dependent on primary lowland forest, heavily impacted by deforestation and palm oil expansion.
