Guide to Boreal Birds
The most widespread ptarmigan of the Far North, this species increases in number in some years but in others is very scarce. While the female incubates, the male guards the territory. When the chicks grow up, several families gather in large flocks and often migrate southward together when winter arrives. In summer ptarmigans feed on green shoots, buds, flowers, and insects; in winter they take mainly twigs and buds of willows and alders. The Willow Ptarmigan is also the state bird of Alaska.

Summer males of other ptarmigan species more grayish. Winter Rock Ptarmigan has black stripe through eye. White-tailed Ptarmigan has entirely white tail.
