21-4-2024 BANDHAVGARH, INDIA - BLACK DRONGO (Dicrurus macrocercus)

The Black drongo (Dicrurus macrocercus) is a small Asian passerine bird The species is known for its aggressive behavior towards much larger birds that invade its territory. The Black drongo has been introduced to some Pacific islands, where it has thrived and become abundant to the point of threatening and causing the extinction of native and endemic bird species there.

Black drongos are glossy black birds 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 (not crimson as in the similar ashy drongo). The sexes cannot be told apart in the field. Juveniles are brownish and may have some white barring or speckling towards the belly and vent, and can be mistaken for the white-bellied drongo. First-year birds have white tips to the feathers of the belly, while second-years have these white-tipped feathers restricted to the vent. Black drongos fly with strong flaps of the wing and are capable of fast maneuvers that enable them to capture flying insects. With short legs, they sit upright on thorny bushes, bare perches, or electricity wires. They may also perch on grazing animals.
