Greater sage-grouse

The greater sage-grouse (Centrocercus urophasianus) is an iconic species of the sagebrush-steppe ecosystem of the American West. The largest grouse in North America at up to seven pounds, it is one of the few wildlife species completely dependent on sagebrush habitat.

The greater sage-grouse was once widespread and tremendously abundant, ranging across portions of thirteen western states and three western Canadian provinces. It has declined significantly during the last fifty to seventy years, currently inhabiting only eleven states and two provinces—less than 60 percent of the range it occupied prior to Euro-American settlement.

Greater sage-grouse numbers continue to decline, and the species is a candidate for listing under the Endangered Species Act. In 2010, the United States Fish and Wildlife Service declared the greater sage-grouse “warranted but precluded” from federal protection; although imperiled, it is currently a lower priority than some other, more critically threatened species. Elimination, fragmentation, and degradation of sagebrush habitats are generally considered to be the primary causes of the decline of greater sage-grouse.

In spring, male sage-grouse perform elaborate displays to attract females in communal mating grounds called leks. This specimen introduces visitors to a lek in the Draper Museum’s Plains-Basin Environment.
