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.
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.
