Red-breasted Swallow
Cecropis semirufa
The red-breasted swallow is similar to the mosque swallow but is slightly smaller and has longer tail streamers, both species having a blue crown and mantle contrasting with a rufous rump and underparts, In the red-breasted swallow the dark crown extends below the eye and there is no white on the underwing. The juvenile is similar to the red-rumped swallow but has blue on the side of the head rather than dull red.

Sri Lanka Swallow
Cecropis hyperythra
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. It is a passerine, which means it has three toes pointing forward and one pointing backward, allowing it to perch.
