Nidification. Within our limits the only record of these birds breeding is that of Hume, who found it in immense flocks on the Cheebaniani Reef of the Laccadives in February. The birds had then just commenced laying and Hume obtained eight eggs which he describes as being like those of Sterna fuscata but more brightly coloured. Sir W. J. F. Williamson obtained a fine series on one of the small islands in the Gulf of Siam and these, laid in May, are like all other Noddy's eggs much less richly marked than those of the Sooty Terns. The ground is white, sometimes faintly tinged with grey, stone-colour, greenish or pink but in none at all rich or deep. The markings generally consist of sparse blotches and spots of dark reddish-brown with secondary markings of lavender-grey. The blotches are generally more numerous at the larger end and in a few eggs are comparatively bold and handsome. Only one egg is laid on the bare rocks, with no nest, quite in the open. Twenty-seven eggs average 51.8 x 35.8 mm.: maxima 55.2 X 35.0 and 53.1 x 37.2 mm.; minima 49.5 x 34.8 mm.

Habits. The Noddies are oceanic birds, only frequenting land regularly during the breeding-season and then selecting, for the most part, rocky reefs and small islands or the wilder more broken areas on the large islands. Their flight is in appearance much slower and more lethargic than those of the Terns; they wheel about more lazily, seldom, if ever, hover and then plunge after their fish prey, but settle on the sea, feeding on small surface mollusca, dead fish and floating oddments. During the breeding-season they and their young feed entirely on the small Sepida cephalapods which form the food of the Sooty Terns.
