Habitat:
Found in foothills, plains and mountain slopes where sagebrush is present, or in mixture of sagebrush, meadows, and aspen in close proximity. In some areas, suitable winter habitat is probably most limiting seasonal factor.

Diet:
Feeds on sagebrush during winter. At other times of year, feeds on sagebrush as well as leaves, blossoms, and buds of associated plants. Also eats insects (e.g., ants and grasshoppers).

Ecology:
Builds concealed nest in depression on ground under sagebrush. Forages in foliage, or on ground. lekClick word for definition breeder; up to 400 males may display in area 0.8 km long. In Idaho, populations may move 0.2-81.0 km from summer to winter range. Agricltural areas are important component of summer rante; sagebrush stands are more important in winter. In Idaho study, nesting success was higher in sagebrush versus non-sagebrush sites. Other Idaho investigations by the Dept. Fish & Game are examining the impact of wildfire in shrub steppe on sage grouse.
