The Mountain Bamboo Partridge has a brown head and olive-toned back, with chestnut spots across its breast. It uses forest, scrub, grassland, and bamboo cover.
The head is brown and the back and wings are olive-grey, with chestnut spots on the breast. The pale brown belly meets spotted black flanks; the male has a black eye stripe while the female's is brown.
Mountain Bamboo Partridges forage on the ground and roost together on low tree or bamboo branches. They use scrub and grass on slopes as well as bamboo stands. Outside breeding, family groups may forage in grassy field margins.
A 1991 field report described birds beside the Noa Dihing River in northeastern India. The researchers made eight ornithological expeditions in the basin during 1979–1988. They observed Mountain Bamboo Partridges in riverine scrub at Ramnagar in February 1988 and cut-over scrub around Gandhigram in March.
The birds travelled in small parties and flushed readily. Several called together, producing a complex, strident but musical sound most often heard in the early morning. They also ate rice grains remaining in fields beside the river. These observations connected flock movement, morning voices and farmland feeding within one valley.
An extinction-risk assessment has not been added yet.
The 1991 Noa Dihing report described degradation of unprotected forests and their bird communities, and called for protection of Namdapha National Park against poaching and illegal extraction of forest products. These were regional recommendations from the period, covering the basin where Mountain Bamboo Partridges were also observed.
