The '''forktails''' are small [insectivorous](/source/insectivore) birds in the [genus](/source/genus) '''''Enicurus'''''. They were formerly placed in the [thrush](/source/thrush_(bird)) family, [Turdidae](/source/Turdidae), but are now treated as part of the Old World flycatcher family, [Muscicapidae](/source/Muscicapidae). Their common name derives from their long forked tail.<ref name = "HBW">{{Citation | first = Nigel | last = Collar | editor-first = Josep | editor-last = del Hoyo | editor2-first = Andrew | editor2-last = Elliott | editor3-first = David | editor3-last = Christie | contribution = Family Turdidae (Thrushes) | title = [Handbook of the Birds of the World](/source/Handbook_of_the_Birds_of_the_World).

These are southeast [Asia](/source/Asia)n forest species principally associated with mountain forests and streams. Most nest in rock crevices, laying 2–4 [eggs](/source/egg_(biology)).

==Taxonomy==
The genus ''Enicurus'' was introduced in 1822 by the Dutch zoologist [Coenraad Jacob Temminck](/source/Coenraad_Jacob_Temminck) to accommodate ''Enicurus coronatus'', the [white-crowned forktail](/source/white-crowned_forktail), which is therefore the [type species](/source/type_species).<ref>{{ cite book | last=Temminck | first=Coenraad Jacob  | author-link=Coenraad Jacob Temminck | year=1824| title=Nouveau recueil de planches coloriées d'oiseaux, pour servir de suite et de complément aux planches enluminées de Buffon | volume=3 | at=Livraison 19, Plate 113 | publisher=F.G.
