Red grouse by sheep. Conservation measures taken on foot of the judgment have seen the population in the area double from 400 to 800. The red grouse is considered a game bird and is shot in large numbers during the shooting season which traditionally starts on August 12, known as the Glorious Twelfth.

Gunnison grouse exist. Gunnison sage-grouse occur in seven counties in southwestern Colorado and one county in southeastern Utah. Males gather on the lek or strutting grounds, which are small, open areas where breeding occurs, in late February to April, as soon as the lek is relatively free of snow. Only a few dominant males, usually two, breed. After mating, the hen leaves the lek for the nesting grounds. Clutch size ranges from six to eight eggs; incubation time is 25 to 27 days. Sage-grouse apparently have high rates of nest desertion and nest predation. Gunnison sage-grouse are totally dependent on sagebrush-dominated habitats.
