Grouse?!? in Arizona

On the way up Humphreys Peak, near Flagstaff, Arizona, I came upon about five of these lovely birds.  Grouse?!?   I've never seen grouse in Arizona!  

After I got home, I looked it up.  I'm assuming these are dusky grouse, which my Dad has apparently seen in the wild in Arizona.  But it was a treat for me.  As I was alone on the trail, I got to watch them for a good ten minutes.  Not a bad way to spend your time.
