The Sooty Grouse is a species of forest-dwelling grouse native to North America's Pacific Coast Ranges. It is closely related to the Dusky Grouse , and the two were previously considered a single species, the Blue Grouse.
Adults have a long square tail, light gray at the end. Adult males are mainly dark with a yellow throat air sac surrounded by white, and a yellow wattle over the eye during display. Adult females are mottled brown with dark brown and white marks on the underparts.
