IUCN Conservation Status: Least Concern
One of North America’s largest grouse, the Dusky Grouse used to be considered the paler, interior subspecies of the Blue Grouse. Recent DNA evidence supports the spilt of the Blue Grouse into two separate species, the Dusky Grouse and the Sooty Grouse. The male’s deep booming call is hard to locate.
Male makes very deep hooting. Female makes cackles and whinnies.
