Dusky Grouse

Dusky Grousedg – Dendragapus obscurus

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.
