The Dulit partridge, also known as Hose's partridge, has been considered a distinctive subspecies of the long-billed partridge, a bird in the Phasianidae, or pheasant, family. It is endemic to Borneo, where it appears to be separated altitudinally from the nominate subspecies, and is often considered now to be a full species, Rhizothera dulitensis. It is little-known, rare, and has not been recorded since 1902.
Region
Borneo
Typical Environment
Occurs in lower montane and hill forests of northern Borneo, especially in Sarawak and adjacent ranges. It favors dense understory in primary forest with bamboo, rattan, and palms, often along ridges and steep slopes. The species is terrestrial and keeps to the forest floor, where it moves through leaf litter and undergrowth. It is believed to avoid heavily disturbed or logged habitats and is highly secretive.
Altitude Range
900–1700 m
Climate Zone
Highland

Also called Hose's partridge, this elusive ground-dwelling bird is known only from a few historical specimens from northern Borneo and is often treated as a full species distinct from the long-billed partridge. It appears to occupy higher-elevation forests than its close relative and has not been reliably recorded since the early 1900s. Ongoing threats include habitat loss and snaring, and targeted surveys are needed to confirm its continued existence.
Temperament
shy and secretive
Flight Pattern
short rapid wingbeats; prefers running to flying
Social Behavior
Typically observed in pairs or small family groups, foraging quietly on the forest floor. Likely monogamous with ground nests concealed in dense cover. Breeding biology is poorly known but presumed similar to other partridges, with a small clutch and both parents remaining close to cover.
Migratory Pattern
Resident
Song Description
Vocalizations are poorly documented, but thought to include soft, whistled notes given at dawn and dusk. Calls are low and ventriloquial, carrying through dense understory.
