A female willow ptarmigan ruffles its feathers along the Savage River near the Savage Canyon Trail in Denali National Park and Preserve in Alaska. Ptarmigan have feather covered feet to help protect from frozen ground. Its plumage is seasonal. During the winter their feathers turn to white to help camouflage the bird against predators.
