Pacific Swift

The Pacific Swift is a dark, fast-flying swift with long, swept wings and a forked tail. It resembles the Common Swift, but a conspicuous white rump band and more heavily marked underparts provide useful separation. Adult males and females look alike, whereas young birds show pale fringes on their wing feathers. Its voice is a sharp screech typical of swifts. The species belongs to a closely related Asian complex whose members were formerly treated as a single species. (Wikipedia, general species account)

Pacific Swifts live largely on the wing and take flying insects while coursing through open airspace. They occupy many climatic zones and are not confined to one narrow habitat type. Breeding occurs across eastern Asia, while winter brings a long southward movement to Southeast Asia and Australia. Their aerial life, pointed wings and streamlined shape support sustained travel and rapid feeding flight. Like other swifts, they normally approach land most closely at nesting sites on cliffs or human structures. (Wikipedia, general species account)
