White-tailed Ptarmigan

These birds are super cool, and not just because they love a good alpine environment. They come equipped with built-in snow boots! Yeah, thats just extra feathers around their feet, but a nice winter adaptation at any rate.  And check out the sweet camouflage the late summer plumage provides. This shot also came from Rocky Mountain National Park, just a dozen feet or so below the Forest Canyon Overlook.
