The black bulbul (Hypsipetes leucocephalus), also known as the Himalayan black bulbul or Asian black bulbul, is a member of the bulbul family of passerine birds. It is found in southern Asia from India east to southern China. It is the type species of the genus Hypsipetes, established by Nicholas Aylward Vigors in the early 1830s.[2] There are a number of subspecies across Asia, mostly varying in the shade of the body plumage (ranging from grey to black), and some also occur in white-headed morphs (as also suggested by its specific epithet leucocephalus, literally "white head"). The legs and bill are always rich orange-red. The related form from the Western Ghats and Sri Lanka is often treated as a separated species, the square-tailed bulbul (Hypsipetes ganeesa).
