Swifts are among the fastest flying birds. The spinetailed
swifts of eastern Asia are the fastest known birds which have been timed at
over 200 km/h in level flight. Swifts catch insects while flying, swooping
through swarms of insects with their gaping mouth, wide open. They often fly
throughout the night without landing. Other fast fliers include peregrine

driving on prey. Swallows are believed to reach 160km/h while migrating and
homing pigeons can generate speed up to 80km/h.
