Moussier's redstart (Phoenicurus moussieri) is a small passerine bird in the genus Phoenicurus (redstarts), formerly classed as a member of the thrush family (Turdidae), but is now classified as an Old World flycatcher (Muscicapidae). It is an endemic resident breeder in the Atlas Mountains of northwest Africa. Its habitat is open woodland in rocky areas from sea level up to 3000 m altitude in the mountains. It is the smallest redstart, only 12 cm long and 14–15 g weight. The male has a black head with a broad white stripe running above each eye and down the side of the neck. The upperparts are black other than a white wing patch, and the rich chestnut tail, from which it and other redstarts get their names (start is an old word for tail). The underparts are a rich orange-red. The female has a pale brown head and upperparts, and the underparts are a paler orange than the male, although generally redder than the underparts of the similar but larger female common redstart. It is named after Jean Moussier (1795–1850) who was an amateur naturalist and a surgeon in the French Army during the Napoleonic Wars.
