Song & Call Comparison
Ferruginous Partridge
Sharp, staccato 'krik-krik-krik' calls from lowland rainforest; often given in duet. Alarm is a loud, rapid chattering rattle; contact notes between pairs soft and clucking.
Salvadori's Pheasant
Infrequently recorded 'kak-kak' alarm calls; Sumatran montane endemic. Vocally poorly known. Contact between birds presumably low guttural clucks. Flushed birds produce loud wing clatter.

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.
Salvadori's Pheasant
A medium-sized Phasianidae pheasant (~685 g) restricted to montane forests of Sumatra above 1,000 m. Both sexes are sombre dark brown, the male with a finely laced pale pattern. Little studied; forages on seeds and invertebrates on forest floor. Near Threatened from montane forest loss in Sumatra.
