Males weigh 330 to 1,000 g, whereas females weigh 700 g and females weigh more than 800 g, with females weighing around 50% more than their male mating partners not unusual.Still, like many other birds of prey, the peregrine falcon exhibits substantial sex differences in size, with the female measuring up to 30% more significant than the male. The male and female have identical markings and plumage. The peregrine falcon is 34 to 58 cm (13-23 in) in length and has a wingspan of 74 to 120 cm (29-47 in). ![]() See the fact file below for more information about Peregrine Falcon, or download the comprehensive worksheet packs, which contain over 11 worksheets and can be used in the classroom or homeschooling environment. The peregrine falcon is famous for its speed, soaring up to 320 km/h (200 mph) during its distinctive hunting stoop (high speed dive), making it the fastest animal in the world. It is a vast falcon the size of a crow, with a blue-grey back, barred white underparts, and a black head. The peregrine falcon, also recognized as the peregrine and formerly as the duck hawk in North America, is a worldwide raptor in the Falconidae family.

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. 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. 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. Advertisementsĭuring 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. Some experimental dives have suggested that even higher speeds are possible by this species, perhaps up to 389 km/h (242 mph). 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. ![]()
