Endemic to Sri Lanka, this swallow was formerly treated as a subspecies of the red-rumped swallow. It is noted for its richer rufous underparts and rump. Pairs build enclosed, flask-shaped mud nests under bridges, culverts, and rock overhangs. It is a capable aerial hunter, often seen hawking insects over paddy fields and open country.
