A large black drongo with a notched tail and long, racketlike outer tail streamers, a glossy neck, and an obvious crest that curves backwards. Juveniles are duller and often lack the tail streamers. Prefers woodlands and forests where it may be found associating with mixed flocks, other drongos, and birds such as treepies and babblers. Similar to other drongos when without tail, but combination of notched tail, crest on forehead and medium-sized bill set it apart. An accomplished mimic with variety of vocalisations including metallic jingling sounds.
