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.
Ahanta Spurfowl
A medium Phasianidae spurfowl (~548 g) of lowland and secondary forest edges in West Africa from Ivory Coast to Nigeria. Dark brown streaked white; red orbital skin. Forages on the ground in pairs or small groups for seeds, berries, and invertebrates. Tolerates forest fragments; Least Concern.
