The Black Drongo (Dicrurus macrocercus), also known as the King Crow, is a small Asian passerine bird of the drongo family Dicruridae. Previously considered a subspecies (Dicrurus adsimilis macrocercus) of the African Fork-tailed Drongo (Dicrurus adsimilis), it is now recognized as a full species. It is a common resident breeder in much of tropical southern Asia from southwest Iran through India and Sri Lanka east to southern China and Indonesia. It is a wholly black bird with a distinctive forked tail and measures 28 cm (11 in) in length. Feeding on insects, it is common in open agricultural areas and light forest throughout its range, perching conspicuously on a bare perch or along power or telephone lines. The species is famous for its aggressive behaviour towards much larger birds, such as crows, never hesitating to dive-bomb any birds of prey that invades its territory. Smaller birds often nest in the well guarded vicinity of a nesting Black Drongo.
