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.
White-tailed Ptarmigan
The smallest ptarmigan (~360 g) of family Phasianidae; the only ptarmigan with a white tail year-round. Inhabits alpine tundra and rocky slopes above treeline in the Rocky Mountains from Alaska to New Mexico. Plumage turns all-white in winter for camouflage. Feeds on willows, sedges, and berries. Least Concern; well adapted to extreme mountain environments but vulnerable to climate warming.
