Hainan Partridge
A small partridge (~245 g) of family Phasianidae, with black-and-white facial markings and rufous breast. Endemic to Hainan Island, China. Inhabits tropical and subtropical montane forests, increasingly confined to higher elevations due to lowland deforestation. Forages on the forest floor for seeds and invertebrates. Vulnerable; very restricted island range with severe habitat loss over past decades.
Hill Partridge
A medium-sized partridge (~340 g) of family Phasianidae, with intricate rufous, black, and white patterning and an orange-rufous head. Inhabits subtropical and montane broadleaved forests and bamboo thickets in the Himalayas from Pakistan to southwestern China. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; common in Himalayan foothills.
