At ten months, the common swift is the bird that can fly the furthest distance without landing.
Common swifts travel ten months in the air during their non-breeding season, from Europe to Africa and back.
Swifts' sleek bodies and long, narrow wings allow them to use extremely little energy throughout their lengthy flights.
While in the air, swifts mate, feed, and gather materials for their nests.
Swifts' broad wings and small legs prevent them from landing on the ground, but they can land on nest boxes, branches, and houses.
Studies have revealed that they spend practically all of their migration in the air, landing on land for just 0.64% of it.
Swifts can take advantage of dynamic food sources like flying insects by staying in the air.
