Life Cycle

Greater Sage GrouseDuring mating season, male sage grouses gather on a lek or a special display area. While they are there, they strut and display their plumage to attract a mate.

The female lays 6-9 eggs in a depression in the ground lined with grass. The nest is usually under a bush or other cover. The female incubates and cares for the chicks.

Greater Sage GrouseThe chicks hatch in about three weeks and feed themselves soon after hatching. They eat insects for the first few weeks but soon move on to weeds, grasses, and sagebrush. The chicks fledge in about a week.

Behavior

The greater sage grouse doesn't have a muscular gizzard with grit in it, and it can't digest hard foods like seeds.
