Dendragapus

The genus Dendragapus contains two closely related species of grouse that have often been treated as a single variable taxon (blue grouse). The two species are the dusky grouse (Dendragapus obscurus) and the sooty grouse (Dendragapus fuliginosus). In addition, the spruce grouse and Siberian grouse have been considered part of this genus.
