Willow ptarmigan (female and male)        Images © Mark A. Chappell

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.
