About These Birds
Rock Partridge
A medium Phasianidae partridge (~633 g) of rocky alpine and subalpine terrain in the Alps, Balkans, and Apennines. Very similar to Chukar but with a broader black face border and whiter throat. Inhabits steep rocky slopes above 600 m. Feeds on seeds and plant material. Near Threatened from tourism pressure.
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.
