The willow ptarmigan is an iconic resident of the North American tundra. Males are rusty brown and white in summer (the one above is a little ragged, as he is molting), and females are highly camouflaged. In winter, both sexes are pure white (with black tails). The birds above were photographed near Churchill, Manitoba; the ones below (including chicks) were in Denali National park, Alaska; some of these are moulting from juvenile into adult plumage. |
