Young et al., 2000,
approximately 23 km south-east of Gunnison, Gunnison County, Colorado, USA.
A cryptic species previously included under C. urophasianus; not until mid-1980s and early 1990s were the differences from latter in morphometrics, breeding behaviour and plumage discovered, including significantly smaller size (400–800 g less in males)#R and different display#R. Some genetic data are available to support the treatment of this population as a new species#R#R. Monotypic.
Confined to Gunnison Basin, in SE Utah and SW Colorado, in WC USA.
Formerly, it presumably occurred also in NE Arizona, N New Mexico, NW Oklahoma and Kansas#R.
