The winter plumage is less distinct. The throat and underside of the neck become white, but traces of the stripes remain on the shoulders. The underside of the body is white and the upper surfaces are dark grey with alternating dark grey and slightly paler grey stripes along the wings. Juvenile birds have a more scalloped pattern on the wings. There is also a triangular white patch of feathers on each flank near the tail end.
