About These Birds
Przevalski's Partridge
A large Phasianidae partridge (~553 g) of rocky semi-arid terrain and loess gullies in the Gansu corridor and adjacent Yellow River basin, northern China. Closely related to Chukar but notably larger. Feeds on seeds, leaves, and invertebrates. Tolerates cold winters; forms winter coveys. Least Concern.
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.
