Winter plumage.—Whole throat, foreneck, malar, subocular, 
and auricular regions, and sides of occiput white, the last separated 
(except posteriorly) by a narrow blackish postocular stripe; white 
of latero-occipital area and lower part of foreneck faintly mottled 
transversely with dusky; otherwise as in summer.
