Dulit Partridge
Rhizothera dulitensis
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.

Species Profile
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.
The Dulit Partridge faces significant threats from habitat loss and degradation due to deforestation, logging, and agricultural expansion across its limited range in Borneo's montane forests. Its restricted distribution and specialized habitat requirements make it particularly vulnerable to environmental changes and human encroachment.
Key Facts
Habitat & Distribution
Inhabits primary and secondary montane forests in the highlands of Borneo, typically found at elevations between 900-1,500 meters. Prefers dense understory vegetation in hill and lower montane forest zones with rich leaf litter for foraging.
Threats
Agricultural expansion and land conversion
Deforestation and logging
Climate change impacts on montane ecosystems
Habitat fragmentation
Limited range and small population size
