About These Birds
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.
Chinese Grouse
A small grouse (~335 g) of family Phasianidae, similar to Hazel Grouse but with more chestnut tones. Endemic to montane forests of central China, including Gansu, Sichuan, and Qinghai. Inhabits dense broadleaved and coniferous montane forest at 1,500–4,000 m. Feeds on seeds, buds, and berries. Near Threatened due to restricted range, logging pressure, and limited population data.
