Song:
Male
makes a bubbling pop-pop sound as air is released from air sacs during courtship
ritual. Clucks like a chicken when flushed.
Distribution:
Previously widespread. Resident locally from
central Washington, southern Idaho, Montana, and parts of southern Canada and Great
Plains, south to eastern California, south-central Nevada, southern Utah, western Colorado
and northern New Mexico.
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. lek
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.
