This little House-Swallow extends from Arakan to Tenasserim and thence to Java, Sumatra, Borneo, Philippines and other islands. It also breeds in the Andamans.
The only record of this bird’s breeding noted in Hume’s ‘Nests and Eggs' is that of Theobald, who says that in Tenasserim it “lays in the second week in April. Nest a saucer of mud ; inner part coarse roots, profusely lined with feathers and vegetable down, attached to the under parts of snags projecting some 4 feet above the water.”
Hopwood found it breeding on the sea-coast in Arakan, its northernmost limit, while Anderson and Osmaston took numerous nests in the Andamans.
The nests are built either in small scattered colonies or, more often, singly, on cliffs or rocks or, less often in Burma and the Andamans, more often in Sumatra, Java etc., under the eaves of buildings.
In Tenasserim Hopwood found them breeding on a high cliff over¬looking the sea, about 18 feet from the top and nearly 30 feet from the base but easily approached from above. In the Andamansthey bred both on rocks, under the shelter of an overhanging ledge, or in small caves on the sea-shore. All these nests seem to have been built quite low down, sometime within 4 or 5 feet of the ground.
The nests are the same, wherever built—typical little nests of Swallows, half saucer-shaped and made of tiny pellets of mud with a lining of soft feathers. The coarse roots and vegetable down mentioned by Theobald must have been quite abnormal, though often small oddments of grass etc. are picked up by the birds when collecting mud.
In Tenasserim and Arakan the breeding season is, so far as yet known, March and April but, in the Andamans, eggs were taken from the first week in May to the end of June. It appears, therefore, that they are single brooded, though information is incomplete on this point.
The eggs number two to four and are just small replicas of the eggs of the Common House-Swallow, but are, perhaps, a little broader in proportion to their length. A comparatively large proportion of the eggs are rather heavily and richly marked with chestnut-brown. As in the eggs of their larger relatives, secondary spots are very few in number and often entirely absent. When present they may bo either pale washed-out reddish-brown or pale neutral tint.
Forty eggs average 17.5 x 12.7 mm. : maxima 19.0 x 13.0 and 18.3 x 13.1 mm, ; minima 16.0 x 11.9 mm.
