A medium-sized partridge (~270 g) of family Phasianidae, with a chestnut breast and finely barred plumage. Inhabits subtropical and montane forests in the eastern Himalayas from northeastern India through Bhutan to southwestern China. Forages for seeds and invertebrates on the forest floor. Near Threatened due to forest loss and hunting across its Himalayan foothill range.
