The forktails are small insectivorous birds in the genusEnicurus. They were formerly placed in the thrush family, Turdidae, but are now treated as part of the Old World flycatcher family, Muscicapidae. Their common name derives from their long forked tail.[2]
These are southeast Asian forest species principally associated with mountain forests and streams. Most nest in rock crevices, laying 2–4 eggs.
The following cladogram showing the relationships between the species is based on a molecular phylogenetic study of the Old World flycatchers published in 2023. The Bornean forktail (Enicurus borneensis) was not included.[6]
