Swifts are a bird species that primarily feed on insects caught while flying, including flies, mosquitoes, beetles, and moths. They have a unique behavior where they fly continuously, hunting until they return to their roost. Swifts eat a wide range of insects, including flies, ants, beetles, and spiders. Adults eat one to three times an hour, and some birds eat ten thousand insects a day.
White-throated Swifts eat insects and spiders, which they capture in the mouth while flying. Their flight is rapid, twisting, and acrobatic, and they often turn sharply to sweep back through a particularly insect-rich part of the air column. Swifts line their nests with any suitable items they can catch as they fly through the air, sticking it together with saliva.
White-throated Swifts use their speed and agility to catch flying insects on the wing, catching up to around 12 mm (0. 5 in) of insects at speeds of up to 25 mph. They can fly at altitudes of 2300 m (7550 ft) on clear days and feast on small flying insects by catching them in flight. Insects collect in a special pouch at the back of the swift’s throat.
Chimney swifts can catch their prey in flight, snatching insects from mid-air, but how often they do this is even more impressive than their impressive speed and cavity-nesting tendencies. Swifts can also feed on “aerial plankton” such as flying ants, aphids, mosquitoes, and other insects. In their lifetime, a swift may fly well over a million miles.
