About These Birds
Tan-breasted Partridge
A medium-sized partridge (~335 g) of family Phasianidae, with plain tan-brown breast and muted brown upperparts. Endemic to the Natuna Islands of Indonesia. Inhabits tropical forest. Forages on the forest floor for seeds and invertebrates. Least Concern; while restricted to small islands, remains stable; its insular endemism makes it vulnerable to future habitat clearance or introduced predators.
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.
