About These Birds
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.
Black-billed Capercaillie
A very large Phasianidae grouse (~2.96 kg) of Siberian larch and pine forests east of the Yenisei River. Closely related to the Western Capercaillie but distinguished by an all-black bill. Lekking males fan tail feathers dramatically. Feeds on needles and buds; Least Concern.
