The White-bibbed Swallow has glossy blue-violet plumage and a white throat patch. It catches insects while flying low over rivers.
Adults have a metallic blue sheen from head to back and belly, with a violet gloss especially on the head. A white patch marks the middle of the throat; the tail is short and broad, with white marks on the inner feathers.
It flies low over rivers to catch insects in the air. Pairs hold a short stretch of river around the nest and are usually seen alone or in small groups.
