White-bellied Drongo

Its tail fork is shallower than the black drongo's. Birds under a year old lack the white below and are browner above and greyish below, and may be mistaken for the smaller, more compact black drongo. Northern birds are larger, and the extent of white decreases with size (Wikipedia, general species account).

Like other drongos it is insectivorous. Three subspecies are recognised (Wikipedia, general species account).
