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.
Bornean Crestless Fireback
A Bornean-endemic Phasianidae pheasant (~934 g) of hill and montane forests. Males have blue-black plumage and red orbital skin without a crest, distinguishing it from the closely related Malay species. Diet includes seeds, fruits, and ground invertebrates. Endangered owing to ongoing deforestation in Borneo.
