It's already the fastest bird recorded in level flight, now researchers have confirmed the common swift can fly for 10 months a year without coming down.
While scientists have long suspected the bird spends most of its life on the wing, the evidence collected has set a new record.
And the bird's incredible journey may mean it travels as far as seven round-trips to the moon over its lifetime.
It's already known that some birds remain in flight for periods of months, including frigate birds and alpine swifts and that the common swift (Apus apus) is adapted to an aerial lifestyle, where food and nest material are captured in the air.
Observations have prompted scientists to believe that common swifts stay airborne for their entire non-breeding period, including migration into sub-Saharan Africa.
