Cecropis daurica hyperythra Hirundo daurica hyperythra The Sri Lanka swallow (Cecropis hyperythra) is a resident breeder endemic to Sri Lanka.

It is closely related to the red-rumped swallow, and was formerly considered a subspecies.

It is a large swallow with a tail which forks deeply, and the combination of deep rufous underside and navy blue rump without any marks is a unique feature of this species.

Its rufous underside can be used to tell it apart from the red-rumped swallow.

[3] It is found in a variety of open country habitats in both the lowlands and foothills in Sri Lanka, including farm fields and lightly wooded areas.
