Our computational fluid dynamics simulations show that the forces that pull on the wings of a diving peregrine can reach up to three times the falcon’s body mass at a stoop velocity of 80 m s 1 (288 km h 1). The peregrine falcon’s body is built to execute high-speed manoeuvres as it dives through the air to snag its prey.

Peregrine Falcon Diving by Alan Benson, downloaded with permission from The Peregrine Fund’s FaceBook page Peregrine Falcon black background by Christian Fritschi, Attriution 2.0 Generic license, Before the strike they turn up, thus putting on the brakes to slow down before passing by their prey for their kill. This is important as Peregrines often kill their prey by diving quickly toward them, then hitting them with bald up feet or scraping them with open talons. not only the worlds fastest bird but also the worlds. This is comparable to 25 times the force of gravity pushing on your body. The average bird travels a respectable 19 to 37 mph (30 to 60 kph), but the peregrine falcon flies at rates between 40 and 60 mph (64 and 97 kph) - and thats just a warm-up. Experiments done have demonstrated that the diving speed of the peregrine falcon exceeds 200 mph. Both Peregrines and Gyrfalcons can withstand up to 25 Gs. According to NOVA, fighter pilots can handle up to 8 – 9 Gs. These birds can also withstand a much higher G-force than humans. In level flight peregrine falcons can reach speeds of between 65 and 90 km/h but when diving can reach over 380 km/h. Kate Davis tells us that the feathers of a Peregrine vibrate in such a way that in a fast dive they make a sound like “tearing a sheet of canvas.” One reason is due to their sleek teardrop body shape and stiff compact wing feathers, which allows them to slip easily through the air with very little wind resistance. How can a Peregrine perform and maintain this speedy life style? A stooping Peregrine may dive vertically, or at an angle as they rocket toward their prey.
