Wikipedia Abstract

The willow ptarmigan (/ˈtɑːr mᵻ ɡən/) (Lagopus lagopus) is a bird in the grouse subfamily Tetraoninae of the pheasant family Phasianidae. It is also known as the willow grouse and in Ireland and Britain, where it was previously believed to be a separate species, as the red grouse. It is a sedentary species, breeding in birch and other forests and moorlands in northern Europe, the tundra of Scandinavia, Siberia, Alaska and northern Canada, in particular in the province of Newfoundland and Labrador. It is the state bird of Alaska. In the summer the birds are largely brown, with dappled plumage, but in the winter they are white with some black feathers in their tails (British populations do not adopt a winter plumage). The species has remained little changed from the bird that roamed the tund
