Black drongos breed mainly in February and March in southern India, and until August in other parts of the country.
Males and females sing in the mornings during the breeding season.
Courtship can include aerobatic chases and they may lock their wings and beaks together, with the pair sometimes falling to the ground.
Displays may be made on the ground.
Pair bonds are retained for a whole breeding season.
The nest is a cup made with a thin layer of sticks placed in the fork of branch, and is built in a week by both the male and female.
Eggs are laid close to the first rains in April.
The usual clutch is three or rarely four eggs laid in a cup nest placed in the fork of an outer branch of tree.
Large leafy trees such as the jackfruit are preferred.
The eggs are pale cream to red with spots and markings and are 26 mm (1.0 in) long and 19 mm (0.75 in) wide.
The eggs are incubated by both parents and hatch after 14 to 15 days.
Nestlings are brooded for the first five days, after which the young are capable of maintaining a fairly constant body temperature.
A second clutch may be laid if the first is destroyed.
Nests are sometimes built in telephone poles.
A nesting territory of 0.003 to 0.012 km² (0.3 to 1.2 hectares) is maintained.

Helpers, offspring from the previous brood, have sometimes been noted to assist in feeding the fledglings at the nest of their parents.
Cases of brood parasitism by the Asian koel have been noted.
An average breeding success of 44% has been noted with the main cause of fledgling mortality being shortage of insect food which in turn was dependent on rainfall.
