Black Drongo

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.
This bird is glossy black with a wide fork to the tail. Adults usually have a small white spot at the base of the gape. The iris is dark brown .
They are aggressive and fearless birds, and although only 28–cm (11–in) in length, they will attack much larger species that enter their nesting territory, including crows and birds of prey.
