Description wikipedia

The slaty-backed forktail (Enicurus schistaceus) is a species of forktail in the family Muscicapidae. A slim, medium-sized forktail, it is distinguished from similar species by its slate grey forehead, crown, and mantle. It has a long and deeply forked tail banded in black and white, a white rump, and a white bar across its primary feathers; the rest of the plumage is predominantly white. The sexes look alike. The bird frequents the edges of fast-flowing streams and rivers, where it hunts small invertebrates by hopping among rocks or flying out over the water. It breeds between February and July, laying 3–4 pinkish, bluish, or white eggs; both sexes incubate the eggs. The slaty-backed forktail is found near streams and rivers in tropical and subtropical regions, occasionally straying further from flowing water to the edges of roads and trails. Generally a solitary bird, it may occasionally be found in pairs, or in family groups in the breeding season. One of its calls has been described as similar to that of the Blyth's kingfisher, for which it has been mistaken. The forktail is found in the central and eastern Himalayas, the Indian Sub-continent, southern China and continental Southeast Asia. Its wide distribution and apparently stable population have led to it being classified as a species of least concern by the International Union for Conservation of Nature.
