The Bornean forktail (Enicurus borneensis) is a small, black and white bird, with a long and deeply forked tail, in the Old World flycatcher family. It is endemic to the Southeast Asian island of Borneo, where it occupies streamside habitats in montane primary forest.^[1]

Taxonomy

It is closely related to the very similar white-crowned forktail (Enicurus leschenaulti) of which it is sometimes considered a subspecies,^[2] and from which it was split because of:^[3]

• a recognizably different type of mitochondrial DNA
• the reduced extent of the white forehead shield, which does not cover the crown
• its larger size and longer tail with four, rather than five, white tail patches
• different calls
• different habitat, with the Bornean forktail replacing the lowland dwelling white-crowned forktail in the mountains and in submontane areas.
