The common redstart (Phoenicurus phoenicurus), or often simply redstart, is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family, (Turdidae), but is now known to be an Old World flycatcher (family Muscicapidae).
The Common Redstart shows some affinity to the European Robin in many of its habits and actions. It has the same general carriage, and chat-like behaviour, and is the same length at 13–14.5 cm long but slightly slimmer and not quite as heavy, weighing 11–23 g. The orange-red tail, from which it and other redstarts get their names ("start" is an old word for "tail"), is frequently quivered. Among common European birds, only the Black Redstart (Phoenicurus ochrurus) has a similarly coloured tail.
The male in summer has a slate-grey head and upperparts, except the rump and tail, which, like the flanks, underwing coverts and axillaries are orange-chestnut. The forehead is white; the sides of the face and throat are black. The two central tail feathers are dark brown, the other tail feathers bright orange-red. The wings are grey-brown in male P. p. phoenicurus but the remiges have white outer webs forming a pale to whitish wing-patch in adult male P. p. samamisicus (see Taxonomy and systematics). The orange on the flanks shades to almost white on the belly. The bill and legs are black. In autumn, pale feather fringes on the body feathering obscure the colours of the male, giving it a washed-out appearance. The female is grey-brown above and buff-white or light orange below. In most females the throat is whitish, but some (older?) females show a dark bib, some even approaching males in appearance. In P. p. samamisicus, many females tend to show a light wing-patch, analogous to the males but much less prominent.
