About These Birds
Sichuan Partridge
A medium-sized partridge (~400 g) of family Phasianidae, with a rich rufous breast and finely patterned brown upperparts. Endemic to montane forests in Sichuan Province, southwestern China at 600–2,500 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Vulnerable; restricted range, habitat degraded by logging and agricultural encroachment in mountain areas.
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.
