Elegant, long-tailed bird with a gray back, pale underparts, and a black chest band. White outer tail is conspicuous in flight. Found along streams, mainly within montane forest. Feeds by walking along the ground, bobbing its tail constantly. Call is a buzzy “tseeet”. Song is a complex and beautiful jumble of high notes and trills. Similar to Cape Wagtail but has gray rather than brown upperparts and has more white in the wings and tail. Also similar to Gray Wagtail but lacks yellow on the underparts.
