Fiji Woodswallow

The Fiji woodswallow is endemic to the major islands of Fiji, namely Viti Levu, Vanua Levu and Taveuni. It is absent from the fourth largest island, Kadavu, but is present on smaller Gau in the Lomaiviti Archipelago. Its natural habitat is tropical moist lowland forests and savannahs, but it has adjusted to human-altered habitats and also lives in cultivated areas; there are even urban populations in Suva and Nadi. In Viti Levu it is found in the highlands, but not on the highlands of Taveuni. Unlike the nomadic populations of Australian white-breasted woodswallows, the Fiji woodswallow is sedentary. Family groups will occupy a tree in which they roost and nest in over several years. It is thought that this is because the climatic conditions in Fiji are less extreme.

The Fiji woodswallow feeds on insects, with moths, butterflies, dragonflies, and grasshoppers being the main prey taken. Most of the prey is obtained by hawking, with birds sitting on prominent perches and sallying after flying insect prey. Prey is usually taken out in the open away from obstacles but is occasionally taken from near the ground. Alternatively the woodswallow may make sweeps over flowering plants and snap at insects. It seldom lands to catch prey. Smaller items of prey are swallowed whole, whereas larger items are taken to a perch and dismembered, with the insect held on the perch with a foot and pecked apart. The wings of some species, such as dragonflies, are often stripped off before swallowing. Family groups will feed each other during the breeding season, and injured birds are fed while they recover.
