Nidification, This Striated Swallow breeds in Trans-Baikalia in July, making a retort-shaped nest of mud under the eaves of buildings The lining is of feathers but sometimes, it is said, of wool. A rather isolated, but apparently regular, breeding place of this form is in the hills of Assam South and East of the Brahmaputra. In Shillong a few birds arrive every year in late July or early August and at once commence building in the offices and houses of that hill station, leaving immediately their family cares are finished in October; indeed, many birds leave at this time, deserting nests containing young or eggs, having suffered some mishap with their first brood. In the North they are said to lay four to six eggs but in Assam they lay three to five. They are pure white, almost glossless, fine in texture and rather pointed ovals in shape, though blunt eggs are not rare. Fifty eggs average 21.0 x 14.6 mm.: maxima 22.0 x 14.2 and 20.6 x 15.0 mm.; minima 16.4 x 13.6 and 17.3 x 13.1 mm.

Habits. Those of the genus and there is very little in them different to the habits of the Common Swallow. They are hardly truly migratory, for there is no great migration movement North to South in Winter; on the other hand, most birds leave their extreme Northern haunts during the coldest months and the few birds seen in Assam certainly only stay from June (Sadiya) to the end of October.
