セグロエンビシキチョウ Enicurus immaculatus

Black-and-white stream-dweller with a long, elegant tail. One of many similar forktails in its range. Most similar to White-crowned and Slaty-backed Forktails; look out for Black-backed’s namesake black back and also a thick white eyebrow which extends beyond the eye, rather than a large pale blotch on the forehead. Inhabits flowing streams, particularly in areas with cover, but can also be found in wet roadside gutters and small canals in pristine areas.
