The spring male is brown above with a reddish neck and white wings and underparts. The female is similar, but lacks the brown. In winter, both sexes become completely white. They can be distinguished from the winter Ptarmigan by habitat, larger size, thicker bill, and lack of black between the eye and bill in the winter male.
The distinctive British form, the Red Grouse (Lagopus lagopus scoticus) has sometimes been considered a separate species. It is a moorland bird, and is basically reddish brown in all plumages, never going white.
The male's song is a loud "go-back go-back".
Lagopus in the scientific name refers to the feathered legs.
