About These Birds
Red-billed Partridge
A small partridge (~225 g) of family Phasianidae, distinguished by its bright red bill on dark plumage. Endemic to montane forests of Sumatra at 700–2,000 m elevation. Inhabits the forest floor and dense undergrowth of subtropical highland forest. Forages for seeds, berries, and invertebrates. Least Concern; restricted to Sumatran mountains but currently stable with sufficient forest cover remaining.
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.
