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.

Inhabits alpine and subalpine rocky slopes and meadows across the Himalayas and adjacent ranges at 3,000–5,000 m elevation. Forages for grass seeds, shoots, and insects. Least Concern; one of the highest-altitude dwelling partridges; well adapted to extreme cold and snow.
