    • 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.


      Taxonomy


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

      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.
