There are several similar photos of grouse. Pretty sure I recall one of a grouse sitting on someone's shoulder (and that was back before Photoshop). The Ruffed Grouse Society magazine will run them from time to time.
They're funny critters. You can bust brush hunting them for hours, maybe hear a few flush but never get a shot. Then you'll be driving down a two-track and one will stroll right out in front of the truck. You can open the door, load the gun, and walk to within a few feet of the bird before you'll get it to flush.
Pheasants seldom act quite that way, although I did have a rooster flush once, land in a tree, and proceed to sit there scolding my dog as I approached. I waited until he flew out of the tree before I shot him.
