Colorado · UplandSharp-tailed grouse

Colorado's regulated sharp-tailed grouse season covers only Columbian sharp-tailed grouse, what CPW's own regulation names "Mountain Sharp-Tailed Grouse", and the regulation's GMU list (4, 5, 12, 13, 14, 23, 131, 211, 214, 441) matches CPW's own account of a northwest-Colorado population that has contracted from 22 historical Western Slope counties down to a Moffat/Routt/Rio Blanco core, plus an active CPW translocation program expanding it back into Grand County (Middle Park) as of April 2026. Colorado also has a second, genuinely separate sharp-tailed grouse population that is not part of this huntable range at all: plains sharp-tailed grouse, a state-endangered subspecies confined to CRP grasslands in Weld, Logan, and Sedgwick counties in the northeast, a population CPW itself tracks separately and does not regulate as huntable. Writing both here as real regions, but explicit that only the Columbian/Mountain population in the northwest is legally hunted.
