how fast is the fastest bird wing beat?
462140
It depends on the size of the bird. The largest, the Giant Hummingbird, has a wingbeat rate of 10-15 per second. The fastest recorded rate was about 80 per second, on a tiny Amethyst Woodstar, and the slightly smaller Bee Hummingbird - the world's smallest bird - may have an even faster rate. Common small North American hummers like the Ruby-throated and Rufous average around 53 per second in normal flight.

This hasn't been measured before, but with some information we can make an educated guess. Thanks to an informative website I have learned that a bumble bee's wings beat 130-240 beats per minute approxamitely. Now we must think of the power these beats can produce. The rate at which they beat would have to steadily increase as altitude increases, a reason why airplanes are limited to certain altitudes, or ceilings.I would have to say, without any wind in the factors, a bumble bee could get up to 50-80 feet in the air. Since the exact bpm of their wings is unknown, it isn't possible, yet, to determine their ceiling.

The fastest anaiml in North America is the same as the fastest animal in the  world: the peregrine falcon.\n\nPeregrines are found on every continent except Antarctica. Peregrines are not only the fastest craetures in the air, they are the fastest in the world. They can fly horizontally at speeds up to 55mph but when flying downward can top 270mph.\n\n_______________\n\n>>>>>>A pronghorn could beat the best human runner in a >>>>>>marathon.\n\nI calls bulls**t. Fast though they may be over short distances pronghorns they have almost no endurance.

"Former Lockheed Raptor chief test pilot Paul Metz says the Raptor has a fixed inlet. Paul Metz has also stated that the F-22 has a top speed greater than 1600 mph (Mach 2.42) and its climb rate is faster than the F-15 Eagle."\n\nHmmm, interesting.  He says that the top speed is greater than Mach 2.42.  I wonder how much greater...

The land speed record for a crocodile is 17 kph (10.6 mph) measured in a galloping Australian freshwater crocodile (Crocodylus jihnsoni).

i beleive according to the man in the castle a swallow had to beat it's wings 43 times every second in order to maintain air speed velocity. That's a european swallow by the way :

Lockheed built the SR71 with a maximum speed exceeding Mach 3. My simple mind has a hard time comprehending Mach 3 but Mach 1 = 741 miles per hour. Other SR71 fun facts include this jet flew 33 miles per minute and was faster than a 30-06 bullet. \n\nThe website listed below indicated the SR71 is the fastest air breathing jet. The X-15 was considerably faster (Mach 6.7) but was rocket powered. \n\nTwo great aircraft that engineers, designers, manufacturers, pilots, maintenance crews, and families can be very proud of.

The SR-71 Blackbird is correct, with an speed of "over" Mach 3.2, which means the exact speed is more than likely still classified.  Specifications are located at the webpage below, and if it's not on there, that's probably because we're not supposed to know it.

The Yamaha Raptor 350 tops out at about 52 MPH. In that general size if you want another 8mph you can get the Kawasaki or the Suzuki 400's. The Honda 400 is in between the Raptor and those two.

Fastest Tennis Serve\nThe fastest tennis service by a man (measured with modern equipment) is 246.2 km/h (153 mph) by Andy Roddick (USA) during a Stella Artois Championship match against Paradorn Srichaphan (Thailand) at the Queen's Club, London, UK, on June 11, 2004.

They are not making sound with their mouth but it is the sound produced by the fast movement of their wings.

Fast? You mean maximum speed or how fast it travel from one point to another? Well, to answer that, I will give you a brief description of the Black Hawk.\n\nThe Sikorsky UH-60 Black Hawk is a medium-lift utility or assault helicopter used by over 20 nations.\nIt has a maximum speed of 184 mph or 296 km/h and climb rate of 708 ft/min or 213 m/min. It's powered by two General Electric T700-700 free-turbine turboshafts. Both engine capable generating 1,560 hp and 1,163 kW. Black Hawk also has a ferry range of 1,380 miles or 2,220 km and combat range of 368 miles or 592 km.\n\nWell, I hope this can help you determine how fast is a Black Hawk helicopter.

Here are my answers, GENTLEMEN first:\n\nFASTEST:     ANDY RODDICK by far. He holds the official record for fastest tennis serve at 155 mph (250 kph, 09/27/04, Davis Cup tie with Belarus, vs. Vladimir Voltchkov). However, some records show that "Big Bill" Tilden blasted a 163 mph (263 kph) serve in 1931. But due to the difference in clocking techniques that time, this record is often not recognized.\n\nMOST CONSISTENT:     IVAN LJUBICIC. He always leads ATP in total number of aces in a year, and highest average per game.\n\nSPECIAL AWARD for serving goes to ROGER FEDERER. He has the most stylish serve, which is too difficult to read. His serves do not need to be fastest to deceive the eyes of his opponent.\n\nOTHER NOTABLE SERVERS: Pete Sampras, Joachim Johansson, Mario Ancic, Ivo Karlovic. (I don't know what's with the Croatians that they serve too hard! Maybe it's the height, or just a product of rigorous training.)\n\nLADIES:\n\nFASTEST:      Brenda Schultz-McCarthy (130 mph). This is a new record, only set last July 2006 in the Western & Southern Financial Group Women's Open in Ohio. She reclaimed her record from Venus Williams (127 mph) served at the tournament in Zurich at the 90's.\n\nMOST CONSISTENT:     WILLIAMS Sisters. Do you notice how their opponents react each time they are on service? Such strong serves for ladies, at times faster than their male counterpart. \n\nSPECIAL CITATION goes to MARIA SHARAPOVA. She has a punishing serve coupled with a very loud grunting. The problem is whether the serve or the shriek troubles the receiver (laughs....)\n\n:  )
