White-tailed Ptarmigan
This is the only species of ptarmigan normally found south of Canada. In summer, its feathers are mottled brown and grayish-white, giving it perfect camouflage in its natural habitat of alpine grasses and forbs and rock outcrops. In winter, it molts to a pure white bird, which allows it to blend in with the snow. While is it able to fly, it prefers to slowly amble along. You can usually get very close to these birds if you move slowly, but as soon as you enter their personal space, they will either pick up their pace to increase the distance or make a short, noisy flight away from you. 12,200 feet--Photo by Jane Hendrix
