Sri Lanka Swallow Cecropis hyperythra

Swallow with deeply forked tail, and unstreaked chestnut underparts and rump. Found in a variety of open country habitats in both the lowlands and foothills, including farm fields and lightly wooded areas, where usually occurs in pairs or small groups. Combination of unmarked, deep rufous underside and rufous rump separate this species from all other swallows on the island.
