This white-tailed ptarmigan’s snowy shade keeps it hidden from predators such as golden eagles and raptors. The only ptarmigan species that dwells south of Canada, it turns mottled gray brown, with white wings, underside, and tail, in the summer and changes to a reddish brown in the fall. Come winter, the ptarmigan is all white except for its eyes and bill. Even its legs and feet are feathered, to help the bird walk on snow.
