This Black drongo was sitting on a wire on the outskirts of Ranthambore. The lyre-shaped tail is of course characteristic. The white spot on the right tail feather is probably a temporary mistake - but the small white spot at the base of the bill is a characteristic of the species! This is a notoriously aggressive bird that attacks significantly larger species, including raptors, when it sees any threat. Other small birds like to take advantage of this and therefore may nest near the Black drongo's nest.
