Phoenicurus is a genus of passerine birds in the Old World flycatcher family Muscicapidae, native to Europe, Asia and Africa. Along with three other closely related genera, they are named redstarts from their orange-red tails ('start' is an old name for a tail). They are small insectivores, the males mostly brightly coloured in various combinations of red, blue, white, and black, the females light brown with a red tail. A molecular phylogenetic study published in 2010 led to a reorganization of the Old World flycatchers family in which the two species in Rhyacornis and the single species in Chaimarrornis were merged into Phoenicurus.
