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.
Sage Grouse
The largest North American grouse (~2.1 kg), family Phasianidae, males with a spiked tail and inflatable yellow air sacs used in elaborate lek displays. Entirely dependent on sagebrush (Artemisia) ecosystems in the western United States and Canada for food and nesting. Feeds primarily on sagebrush leaves. Near Threatened; population severely declined due to widespread sagebrush habitat conversion.
