The Fiji Woodswallow lives on islands in Fiji. An older paper recorded it as the subspecies A. leucorhynchus mentalis and described aerial insect hunting and cooperative care of young.
In the Fiji study, adult males and females showed no obvious difference in appearance.
It flies from a lookout to hawk moths, butterflies, dragonflies, grasshoppers, and other insects. In Suva, groups of three to nine adults shared nesting, incubation, and care of chicks.
An extinction-risk assessment has not been added yet.
