A hardy grouse of barren ground in the high Arctic, well adapted to harsh surroundings. Well camouflaged by white winter plumage and mottled brown summer plumage; male molts later in spring than female, so early in the breeding season he remains conspicuously white while she becomes almost invisible against the tundra.
Far above timberline in mountains of the west lives this elusive little ptarmigan, the smallest member of the grouse family in North America. While the other ptarmigan are strictly northern, the White-tailed Ptarmigan follows the cordillera of the high Rockies as far south as New Mexico. Easily overlooked, it may crouch motionless as hikers pass close by.
