Common swifts are famous for spending extremely long periods in flight, feeding and even sleeping while airborne.
What makes swifts special?
Swifts have narrow, curved wings and streamlined bodies built for continuous flight. They catch tiny insects in the air, so they do not need to land frequently for food like many other birds.
Can they really stay airborne for months?
Research on common swifts has shown that some individuals can remain airborne for most of their non-breeding period, with records close to ten months. They still return to nesting sites for breeding, but their flight endurance is extraordinary.
How do they rest?
Scientists think swifts may rest while gliding at altitude and may use short sleep-like phases during flight. Their lifestyle shows how body shape, energy use, and behavior can evolve together.

Did you know?
Swifts are so adapted to flight that their legs are tiny compared with many perching birds.

Key takeaway
The swift story is a perfect adaptation example: wing shape, food habit, migration, and energy saving all support long-duration flight.
