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.
Gunnison Grouse
A large grouse (~1.6 kg) of family Phasianidae, closely related to Sage Grouse but smaller with longer filoplumes during lek display. Restricted to the Gunnison Basin of southwestern Colorado and a small area of Utah. Entirely dependent on intact sagebrush habitat. Endangered; one of North America's rarest birds with fewer than 5,000 individuals, threatened by habitat fragmentation and drought.
