Previously considered a race of the Greater Racket-tailed Drongo which occurs in the dry zone.  The frontal crest, glossy black plumage and long, deeply-forked tail without the rackets make it easy to identify.  A very vocal mimic that imitates a variety of birds.  Sexes alike.  It inhabits the tall forests of the wet zone ascending to at least to 1600 metres.  It is one of the nucleus species of the feeding waves in Sinharaja Forest.  This handsome bird lives in pairs.
