Looks like Washington gains a species through a split. Blue Grouse has been split into Sooty Grouse - Dendragapus fuliginosus, and Dusky Grouse - Dendragapus obscurus.

Sooty Grouse would be the Coastal to the Cascades species, where the Dusky Grouse would be SE Washington, ie Blue Mts, and I believe North Central-NE part of the state..

Check out the following link for more information. Sibley has both illustrated in his field guide as separate races of Blue Grouse.
