Every where one reads that Peregrine Falcons can reach speeds of 200+ mph. This seems impossible given the huge amount of air resistance at such speed. Is such possible or is this urban legend?
These are peak dive speeds. In level flight a falcon isn't much faster than a pigeon.1colonel said:Every where one reads that Peregrine Falcons can reach speeds of 200+ mph. This seems impossible given the huge amount of air resistance at such speed.
Air resistance at 200 mph is only 4 times that at 100 mph.1colonel said:This seems impossible given the huge amount of air resistance at such speed.
There may be many quotes, claims or assumptions that 200 mph is possible.1colonel said:Is such possible or is this urban legend?
200 mph = 89.4 m/sec, so yes, it does appear to be technically possible.[PLAIN]http://jeb.biologists.org/content/201/3/403.short said:Given[/PLAIN] enough time, ideal falcons can reach top speeds of 89-112 m s-1 in a vertical dive, the higher speed for the heaviest bird, when the parasite drag coefficient has a value of 0.18.
Someone must have put a GPS tracker on a falcon by now.extract from PDF said:– estimates of top speeds range up to 157ms-1 (351 miles h-1) (Brown, 1976; Clark, 1995; Dement’ev, 1951; Hantge, 1968; Lawson, 1930; Mebs, 1975; Orton, 1975; Savage, 1992; Tucker and Parrott, 1970).
While these estimates may be correct, their accuracy is unknown because the speed of a diving falcon is difficult to measure. The required instrumentation is complex, and the dive is a brief, rare event that takes place at unpredictable places and times, usually at a long distance from the observer. Alerstam (1987) used radar to overcome these difficulties, and he measured diving speeds of no more than 39ms-1 in a peregrine. Clark (1995) doubts that diving speeds exceed 41ms-1.

I don't have video bandwidth here, how about a synopsis of the video.

Crazy Brit, complete with obligatory Union Jack crash helmet and specially designed suit, makes like a giant falcon and reaches 300 mph in free fall.

The Peregrine Falcon is the fastest bird in the world, with a top speed of over 200 miles per hour.
The Peregrine Falcon has a streamlined body and long, pointed wings that allow it to fly at high speeds. It also has powerful chest muscles and a flexible tail that help it to maneuver and dive at incredible speeds.
No, the Peregrine Falcon is the fastest bird, but not the fastest animal. The fastest animal is the peregrine falcon, with a top speed of 68 mph.
No, the Peregrine Falcon can only reach its top speed during a dive or stoop. It cannot maintain this speed for an extended period of time.
Yes, the speed of the Peregrine Falcon has been scientifically measured and verified by researchers and scientists. It has also been recorded by high-speed cameras and radar guns.
