Swifts are terrestrial species that require foraging habitat with high numbers of aerial insects. They are found in virtually any temperate or tropical area where prey can be found. Swift habitat includes desert oasis, Mediterranean scrub, steppe, farm or grassland, urban areas, forest and canyons. They can be found from sea level to 4000 m. Because water is an integral aspect of the breeding biology of many species, swifts are usually found near water.
The roosting and breeding site requirements of swifts (traditionally caves or hollow trees, more recently including man-made structures) sometimes necessitate travel of varying distances between roosting and feeding sites.
