How fast can Peregrine Falcons fly?

Peregrine falcons are known for their powerful and fast flying ability and can average 40 – 55 mph.  They are aerial hunters and will drop down on their prey from high above in amazing dives (called “stoops”) that can start 300 – 3000 feet above their prey and reach speeds of over 200 mph. Because of this, they have been reported to be the world’s fastest bird.
