Gunnison Sage-grouse are one of the most endangered birds in North America and a candidate species for listing under the Endangered Species Act. Centrocercus minimus is about 2/3 the size of the Greater Sage-grouse; with voluminous philo-plumage, broad white bands on their tail feathers, distinctly different vocalizations, and sometimes a tail shimmy at the end of the male's display. The Gunnison community, and by extension, southwest Colorado and southeast Utah have rallied for the survival of their native grouse. All of the managing government agencies and local working groups have banded together for habitat improvements and re-populating satellite leks. Population estimates range from 3,000 to 3,500. Satellite leks outside of the gunnison Basin are in serious decline.
