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.

It has a mostly brownish-black crown, with tawny-rufous edges. It also has a tawny-rufous coloured forehead, eyebrow, and hindcrown, which transition into its cinnamon-buff ear coverts, sides of the head, throat, and breast. It has dark brown lores and brown irides. The rest of the upperparts are gray-brown, with a paler rump.
