The Fastest Birds In The World The Peregrine Falcon, a bird of prey, is the fastest bird in the world and can fly at a maximum speed of 389 kilometers per hour. A Peregrine Falcon swooping downward in mid-flight. Birds are unique in the animal kingdom.
The fastest animal on Earth is a cat. Not the domestic one, though. Itâs the cheetah who can accelerate up to a speed of 75 mile per hour which equals 120km/h. Astonishing.
