Swifts are insectivores, they catch their prey while in-flight (hawking) or they glean insects from foliage. Swifts drink by flying near the surface of water with an open mouth. They are often crepuscular (feed at dawn or dusk) and roost during the hottest parts of the day, however, there are some nocturnal and diurnal species.
Swifts will often take advantage of swarming insects such as mayflies (Ephemeroptera). They frequently feed on Hymenoptera (bees, wasps and ants), Diptera (true flies), Hemiptera (true bugs) and Coleoptera (beetles). More than 500 prey species have been recorded in Europe alone.
It is possible to find mixed-species flocks (including swallows (Hirundinidae)) feeding together. Niche-separation is facilitated by differences in gape size that correspond with species size and limits the size of prey that can be taken. Elevation can also separate feeding habitats of different species with larger species usually feeding at higher elevations than smaller species.
