The bird that can fly the fastest is the Peregrine Falcon.
The Peregrine falcon can fly at speeds above 186 miles per hour but only when they are stooping and diving.
A common swift bird was found to fly at 69 miles an hour for the longest time.
The peregrine falcon, also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey in the family Falconidae.
A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head.
The peregrine is renowned for its speed.
Peregrine falcons are top tier, aerial predators that are capable of reaching speeds faster than any other animal in the world.
In a stoop (a rapid dive) to catch prey, they can reach speeds over 200 mph (top recorded speed of 242 mph)!
Falcons are very fast in flight especially the peregrine falcon whereas hawks are much slower in flight and would basically just glide on a descent.
A peregrine falcon, for instance, can reach speeds of 200 mph whereas the red-tailed hawk dives at a speed of at least 120 miles per hour.
The Prairie Falcon is brown and has dark patches under the wings.
Juvenile Peregrine Falcons also have brown backs, but the adults are blue-gray and have a uniform underwing color pattern.
