It appears that four is the maximum number of eggs laid; both sexes participate in the work of incubation and rearing the young, but they are very jealous of the approach of any birds when they have eggs or young, driving all such intruders away with the utmost bravery.  The eggs measure from 0.88 to 0.95 inch by 0.65.

From Sikhim Mr. Gammie writes:—­“I have found the Bronzed Drongo breeding from April to June in the low hot valleys at about 2000 feet above the sea.  It suspends its nest in a slender horizontal fork at 10 feet or more from the ground, and appears, like its frequent neighbour Dicrurus longicaudatus, to prefer a bamboo-clump to breed in.  The nest is a compact cup, neatly made of fine grass-stalks, with an outer coating of dry bamboo-leaves plastered over with cobwebs; it is fastened to the supporting branches by cobwebs.  Externally it measures 3.5 inches wide by 2 inches deep, internally 2.5 by 1.5.

“The usual number of eggs is three.”

Major M. Forbes Coussmaker, writing from Bangalore, tells us:—­“I took the nest of this bird on 6th April in the Shemagah District, Mysore.  It was built on the fork of a bare branch about 20 feet from the ground in big tree-jungle, and was composed of fine grass, fibre, and a few dry bamboo-leaves woven together with cobwebs, making a small compact cup-like nest which measured 3 inches in diameter externally, 2.5 internally, and 1.4 deep.

“From where I stood I saw the bird come and sit on the nest and fly off again a dozen times at least.  The eggs, three in number, measured .9 by .65, and were pinkish white with darker pink and light purple blotches and spots all over, principally at the larger end.”

Mr. J.R.  Cripps informs us that at Furreedpore, in Eastern Bengal, this species is “rather common; generally to be found perching on the dead branches of high trees overlooking water, especially whenever there is a dense undergrowth of jungle.  On the 1st June, 1878, I secured a nest with three fresh eggs; it was built on a slender twig on the outer side of a mango-tree which was standing near a ryot’s house, and was about 15 feet off the ground.  External diameter 31/2 inches, depth 2; internal diameter 2-1/3, depth 1-1/8.  Saucer-shaped; the outside consisted of plaintain-leaves torn up into slips, all of which were firmly bound together by fibres of the plaintain-leaf and jute, which were wound round the twigs and secured the nest.  Inside lining was made of very fine pieces of ‘sone’ grass.  The pair were very pugnacious, attacking any birds coming near their nest.  These birds have a clear mellow ringing whistle.”

Mr. Oates writes from Pegu:—­“I procured one nest on the 23rd April.  It was placed at the tip of an outer branch of a jack tree, and attention was drawn to it by the vigorous attacks the parents made on passing birds.  The nest was suspended in a fork; the outside diameter is 4 inches and inside 3, total depth 21/2, and the egg-cup is about 11/2; deep.  The nest is composed of fine grass, strips of plaintain-bark, and other vegetable fibres closely woven together; the edges and the interior are chiefly of delicate branchlets of the finer weeds and grasses.  It is overlaid at the edges, where it is attached to the branches, with cobwebs, and a few fragments of moss are stuck on at various points.
