Nidification, According to Mr. B. B. Osmaston this Drongo breeds round about Port Blair from April to the middle of May, building a typical Drongo's nest on some dry or leafless tree in forest. The eggs appear to vary in colour almost as much as those of the Common Black Drongos, though pure white eggs have-not been found. Thirty-three eggs average 25.4 x 18.3 mm.: maxima 26.6 x 19.3 mm.; minima 22.3 x 16.5 mm.
Habits those of the family. It is apparently entirely a forest-bird.
