But Franklin insisted that this was only done in order to allow more time for observations and that it made no difference to Frightful's flight behaviour. Some ornithologists have raised doubts about the dives as not recreating natural conditions, e.g., starting at a higher altitude than peregrines would normally dive from. Falcons have thin, tapered wings that enable them to fly faster than a cheetah and turn with immense speed. Falcons are small and incredibly fast birds of prey that have the honor of having the fastest and the smallest bird of prey in North America. The data from all four devices were compared after the dives.įranklin and Frightful's dive experiments were the focus of a National Geographic Explorer documentary entitled Terminal Velocity, which was filmed in 1999 and aired in 2002. The common types are American Kestrel, Prairie Falcon, Peregrine Falcon, and Merlin. Altimeters were also attached to Franklin and a cameraman, who skydived with Frightful during the dives, as well as the lure released to simulate prey for Frightful to chase. To measure Frightful's mid-dive speed, Franklin – working with mathematicians and engineers – used an innovative technique, fastening a 113.4-gram (4-oz) computer chip taken from a a skydiver’s Pro-Track recording altimeter/computer to Frightful’s tail feathers and measured how far she fell in a certain time interval. Frightful, then a six-year-old, 40.64-cm-long (16-in) bird weighing 997.9 grams (2.2 lb), had wings open to a full 104.14-cm (41-in) span. 3 miles (4.8 km) in the air, after being released from a Cessna 172 at 17,000 ft (5,182 m) above sea level. Some experimental dives have suggested that even higher speeds are possible by this species, perhaps up to 389 km/h (242 mph).ĭuring a series of dives in 1999, "Frightful", a peregrine falcon owned by aviator and falconer Ken Franklin of Friday Harbor, Washington, USA, was reportedly clocked at 242 mph (389.46 km/h) while stooping from c. The fastest dive by a bird is that of a peregrine falcon ( Falco peregrinus), which has been estimated at reaching a terminal velocity in ideal conditions of approximately 320 km/h (200 mph) when in a diving stoop hunting prey on the wing.
