Nidification. The Black-necked Stork breeds over the whole of its range from October to December, a few birds laying as early as August and others as late as January. The nest is an enormous structure, varying from three to six feet in diameter by one to two feet deep, with a well-made cavity for the eggs. It is constructed of small sticks and branches and well lined with grass or soft rubbish of some kind and is invariably placed by itself on a tree near the top. The tree may be large or small, standing alone in cultivation or one of a group. The eggs number three or four and are like those of other Storks. Thirty eggs measured by myself average only 69.5 x 53.2 mm. but forty-five measured by Hume averaged 73.9 x 53.8 mm. Maxima 74.9 x 53.4 and 70.6 x 55.2 mm. : minima 67.9 x 54.0 and 68.5 x 51.0 mm.

During the breeding-season, sometimes also at other times, both sexes display by dancing before one another with great flapping of wings and clattering of bills.

Habits. Much the same as those of other Storks but it seems to have a predilection for plains in the vicinity of large rivers and it is, perhaps, a more regular fisher than most Storks, though it eats everything else they do. It is nowhere common numerically although so widespread and is never found in flocks.
