About These Birds
Sand Partridge
A small Phasianidae partridge (~190 g) of sandy desert wadis and rocky slopes in the Middle East and northeastern Africa. Fawn-buff plumage with chestnut flank bars blends with desert substrate. Extremely heat-tolerant; active at dawn and dusk. Feeds on desert seeds and invertebrates. Least Concern.
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.
