The swift is a fast-flying, streamlined bird with long, curved wings and a short, forked tail. Originally nesting on cliffs, it now mainly nests in buildings such as churches, chimneys and even tower blocks; it is particularly common in older parts of towns and cities. Arriving in Britain in April from their wintering grounds in Africa, swifts feast on flying insects.
Although common, breeding populations of swifts have been declining over recent decades. With modern building techniques, the swift's preferred nesting cavities in buildings, such as those under eaves, are becoming few and far between. Specially developed nestboxes may help this species to survive in our towns and villages.
