Active and attractive songbird of open spaces. Breeds in open forests and scrubby vegetation in subalpine areas; winters in a wider altitudinal range in scrubby forest edges, gardens, and fields. Frequently bobs the orange-sided dark tail. Male sports a gray crown and nape, black face, orange underparts, and dark wings with a white wing patch. Females are brownish overall but share the male's bright tail and wing patch. Compare carefully with Common, Hodgson’s, and Black Redstarts. Song is a lively, jingling cascade of warbling; calls include a short, high-pitched whistle and a hard “tsak.”
