The Pacific Swallow has dark, blue-glossed upperparts and a shallow forked tail. It catches insects in flight and ranges from Southeast Asia to New Guinea and the Society Islands.
The upperparts are dark with a blue gloss, and the tail is shallowly forked. The forehead, throat, and upper breast are rufous, while the underparts are grey. Juveniles are duller with a shorter tail.
It flies over open ground, coasts, wetlands, and forest edges, catching insects on the wing. It often forages within about 30 metres of the ground and may roost with Barn Swallows.
