Peregrine falcons have a flicker fusion frequency of 129 Hz (cycles per second), very fast for a bird of its size, and much faster than mammals. [60] A study testing the flight physics of an "ideal falcon" found a theoretical speed limit at 400 km/h (250 mph) for low-altitude flight and 625 km/h (388 mph) for high-altitude flight. [61]
This is a list of the fastest flying birds in the world. A bird's velocity is necessarily variable; a hunting bird will reach much greater speeds while diving to catch prey than when flying horizontally. The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives.
Once the falcons are confident and independent they are either allowed to migrate into the wild, recaptured for falconry and trained further i.e. with a lure for sport, or released into the wild. If the purpose of the hack is to prepare the raptor to be in the wild then the reserve hopes that the falcons will come back in a few years to nest there.
Peregrine falcons are well-known as birds of prey that can fly extremely fast and travel long distances. Peregrines have been timed in stoops, or steep dives, at speeds of 200 miles per hour ...
Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broadwing. This makes flying easier while still learning the aerial skills ...
Are You Smarter Than a 5th Grader?: Science — Because Explosions Are Cool . Which is the fastest-flying bird in the world? Answer: Peregrine Falcon
The same wing shape is used by the auks for a different purpose; auks use their wings to "fly" underwater. The peregrine falcon has the highest recorded dive speed of 242 miles per hour (389 km/h). The fastest straight, powered flight is the spine-tailed swift at 105 mph (169 km/h).
The peregrine falcon is the fastest animal in the world, Audubon's Martin said. "Their flight skills are incredible," he said. "They catch their food in the air."
