Hair-crested Drongo

Hair-crested Drongo is an Asian drongo formerly considered conspecific with the spangled drongo, for which that name is now usually reserved. Some authorities include the Sumatran drongo as a subspecies. It is native from Pakistan, Bangladesh, India and Bhutan through Indochina to China, Indonesia and Brunei, and small flocks are very noisy (Wikipedia, general species account). The species is an Asian bird of the family Dicruridae. (Wikipedia, general species account).

This species was formerly considered conspecific with Dicrurus bracteatus, for which the name "spangled drongo" – formerly used for both – is now usually reserved. Some authorities include the Sumatran drongo (D. sumatranus) in D. hottentottus as subspecies. It is native from Pakistan, Bangladesh, India, and Bhutan through Indochina to China, Indonesia, and Brunei. Hair-crested drongos move in small flocks and are very noisy. The "spangled drongo", Dicrurus bracteatus, is native on the east coast of Australia and its name is a pejorative slang for a silly person. (Wikipedia, general species account).
