42cm. Mottled brown, chicken-like birds with a dark tail.
Males: have a yellow comb above the eye that can be raised during displays, and black-tipped white feathers on the neck that cover reddish patches of bare skin, which are inflatable during displays. Grey band on tail
Females: are mottled brown above and mottled gray below. Brown tail with grey band.

Northern populations of Dusky Grouse (Nevada-Idaho border north) lack the blue-gray tail band seen in Sooty Grouse, but Dusky Grouse in the southern part of the species range (Nevada, Utah, southward) do have the tail band.

[edit] Distribution

Western Canada and western states of the USA in mountainous regions.

Was until 2006 considered conspecific with Dusky Grouse under the name Blue Grouse.
