Pyan-hlwa, Burmese (applied to all Swifts).
Coloration similar to that of T. batassiensis, but much darker, upper parts blackish brown, wing and tail-feathers black above with a slight purplish gloss; lower plumage smoky brown, throat slightly paler.
Bill and feet black; iris brown (Oates).
Length about 5.2 inches ; tail 2.2; wing 4.6 ; tarsus .35; tail less forked than in T. batassiensis; the outer tail-feathers exceed the middle pair by .9 inch.
Distribution. Hill-tracts south of the Assam valley and throughout the Burmese countries, to Southern China, the Malay Peninsula, Borneo, and Java.
Habits, &c. precisely similar to those of T. batassiensis, this bird haunting palms (Borassus and Areca) and breeding in them. In the Naga and Garo hills, where the people thatch their huts with two layers of palm-leaves, this Swift attaches its nest to the upper side of the leaves in the lower layer.
