Red-flanked Bluetails resemble Redstarts in size and shape. Birds in all plumages can be identified by the blue colouring on the tail and rump (though this may not be so evident in all conditions), orange patches on flanks and a clearly defined white throat patch. Males in summer plumage also have blue colouring on their heads, backs and wings. In autumn plumage they resemble females more, but still keep some blue markings on their upper backs. Females are more modestly coloured, with olive brown upper parts (similar to Robin), yellowish white throats, and greyish breasts and bellies. Females also have pale rings around their eyes. Birds in all plumages have dark brown legs and irises, and black beaks.
