"The female differs from the male in having the parts which are

slate-gray replaced by russet-brown, and in having the center of the

throat grayish white, and the cheeks and sides of the throat with brown

fan-shaped terminal spots. Males of the year have the plumage of the

female, and the greater wing-coverts with more or less conspicuous

pale tips. Young in first plumage are unknown." (Seebohm.)
