Fastest animal on the planet... clocked at 220 mph in a dive (i think) I love the color and pattern of this raptor. Everthing about it is dynamic and screams speed. 4h,2h,hb graphite on 8.5"x11" acid free

In responce to a suggestion from someone that the Botfly is faster then a Peregrine Falcon, i looked it up, here's what i found:

-

It was reported for many years that Cephenemyia (Deer Botfly) was the fastest of all flying insects, cited by the New York Times and Guinness Book of World Records as traveling at speeds of over 800 miles per hour. The source of this remarkable claim was an article by entomologist Charles H. T. Townsend in the 1927 Journal of the New York Entomological Society, wherein Townsend claimed to have estimated a speed of 400 yards per second while observing botflies at 12,000 feet in New Mexico.

In 1938 Irving Langmuir, recipient of the 1932 Nobel Prize in Chemistry, examined the claim in detail and refuted the estimate. Among his specific criticisms were:

* To maintain a velocity of 800 miles per hour, the 0.3-gram fly would have had to consume more than 150% of its body weight in food every second;
* The fly would have produced an audible sonic boom;
* The supersonic fly would have been invisible to the naked eye; and
* The impact trauma of such a fly colliding with a human body would resemble that of a gunshot wound.

Using the original report as a basis, Langmuir estimated the deer botfly's true speed at 25 miles per hour.

The Peregrine Falcon is the fastest creature on the planet in its hunting dive, the stoop, in which it soars to a great height, then dives steeply at speeds in excess of 300 km/h (185mph) into either wing of its prey, so as not to harm itself on impact. Although not self-propelled speeds, due to the fact that the falcon gathers the momentum and controls its dive, capture (if any) and landing in its own right, technically there is no faster animal. The fastest speed recorded is 390 km/h (242.3mph). The fledglings practice the roll and the pumping of the wings before they master the actual stoop.
