Tarsus naked ; bill and legs black (Beavan).
Length 4 ; tail 1.5 ; wing 4 ; tarsus .32. Tail nearly square.
Distribution. Andaman and Nicobar Islands, Mergui Archipelago (Blyth), Johore and Malacca, Sumatra, Java, and Borneo.
Habits, &c. similar to those of other species. The nests are usually in caves, and according to Hume and Davison, the latter of whom watched the process of building, consist of brown moss firmly agglutinated with saliva. These nests are never collected for sale, as they are not regarded as edible. The present species at Port Blair in the Andamans has taken to buildings, and even makes its nests at times in inhabited rooms. The eggs, five in number, measure about .7 by .45.
