This Dusky grouse hen froze on the side of the road as I travelled by. This survival strategy works when the predator doesn't have a projectile to make you part of dinner that evening. The Dusky Grouse was split from the Sooty grouse of the western rain forests which used to make up the Blue Grouse species with this grouse being slightly less gray and lighter overall. I have only seen dusky and sooty grouse in the mountains with this being no exception living along Fording River in the Rocky Mountain range.
