White-bellied Drongo
Dicrurus caerulescens
The White-bellied Drongo is a species of drongo found only on the Indian Subcontinent in India, Nepal, Bangladesh and Sri Lanka. Like other members of the family they are insectivorous and is mainly black in colour but with a white belly and vent. Young birds are however all black and can be confused with the Black Drongo although smaller and more compact in appearance and the subspecies found in Sri Lanka has white restricted to the vent.
