Moved "Peregrine Falcon" here to preserve edit history prior to deletion Tannin 10:41 Apr 30, 2003 (UTC) yeah anyway.......falcons would own any of u if they hit u in the head with their talons at full speed :) (no this is not Tannin anymore)

[edit] Source for speed
Does anyone have a source for the high estimate of diving speed ("over 320 km/h")? —JerryFriedman 16:08, 29 Apr 2005 (UTC)
- Have a look at terminal velocity. In fact it shouldn't be the upper limit that is in question but the lower limit. I think the source linked has transposed km/h for mp/h. Simply put, if it died mid air it would fall at about 120mph - a similar speed to a human skydiver. If a sky diver pulls in his arms and goes head first his speed will approach 200mph. Peregrines being as aerodynamic as they are in a stoop easily attain similar speeds. Incidentally I remember seeing a documentary some years ago whith a hand-reared Peregrine that would follow its handler. The handler and a cameraman jumped from a balloon with a significant head start over the bird. Despite the men falling at c.120mph the bird caught up with them in seconds and was filmed easily circling them, visibly having to slow itself to their speed. LiamE 15:51, 7 October 2005 (UTC)
- After a bit of a dig around I have seen claims of over 270 mph recorded on radar guns pointed at Peregrines. Guinness world records entry for the fastest bird reads as follows "Fastest Dive By A Bird - The fastest dive by a bird was recorded in a series of German experiments, when a peregrine falcon reached a velocity of 270.5 km/h (168 mph) at a 30-degree angle of stoop, rising to a maximum of 350 km/h (217 mph) at an angle of 45 degrees. This falcon, also known as a duck hawk, ‘stoops’ by circling high up and then folds its wings back to dive at its prey with their talons." On the basis of that I will edit the article. --LiamE 16:56, 7 October 2005 (UTC)
There was a TV program in the UK in which they tested a falcon I can't remeber which program it was but they couldn;t calculate the speed as it was going so fast. Way faster than any skydiver could go. They thought faster than 250mph though.
Well, here's one that the author might've used- ((http://raysweb.net/specialplaces/pages/falcon.html)). Arosaurer
- Uh, what happened to the speed? I don't see the removal in the History, and I don't have time at the moment to find it. Vandalism? —JerryFriedman 18:03, 13 April 2006 (UTC)
These sources should appear in the article, not only on the talk page. Apus 11:51, 21 September 2006 (UTC)
There was a documentary called Flying With Falcons, shown last night on Channel 5 (UK). In it, falconer Lloyd Buck and a team of balloonists, skydivers and BASE jumpers trained some peregrines to target a brightly coloured bean bag with meat attached rather than the usual swung lure. See [1] for some detail although that is mainly about the camera equipment used. They started training the birds on the ground, then from a tethered hot air balloon, then from cliffs in Devon and finally by jumping from some high bridges and cliffs in Italy (Mount Brento?). As well as high speed camera equipment filmed from different points which could accurately measure their speed, they fitted the birds with tiny accelerometers. The best result they got was from a bird that was already in the air and "waiting on" above the cliff. As the BASE jumper leapt, the peregrine stooped for the lure in his hand. It hit it once, veered off, stooped again and hit it again. During that flight it hit a top speed of 204 mph & pulled 6G! And these are just young birds, 2 or 3 years old. -- SteveCrook 02:06, 7 October 2006 (UTC)
This article is too "America-centric" If these falcons range throughout the world, why is there very little information about these falcons from other parts of the world? This article isn't a sub, but it obviously isn't finished. 01:30, 28 September 2005 (UTC)gazowelz
- They peregrinate (wander), but not usually from one continent to another. I don't think it's very "America-centric". The nominate Falco peregrinus is described as being found over much of western Eurasia. -- SteveCrook 02:11, 7 October 2006 (UTC)
[edit] Source for being a pest
Since people were so helpful about my request for a source for the speed (thank you!), does anyone have a source for the statement that it's considered a pest in rural parts of the U.S.? I find that very hard to believe. —JerryFriedman 17:54, 13 April 2006 (UTC)
[edit] "they live up to 30 years old"
Removed the dubious passage. Just because of the fact that it doesn't say whether in captivity or in the wild.
[edit] Subspecies
"The Barbary Falcon, Falco (peregrinus) pelegrinoides, is often considered to be a subspecies of the Peregrine." Why is this sentence beneath the list of subspecies? Shouldn't it be in it? --Mithcoriel 20:05, 24 September 2006 (UTC)
- No, because it's often considered to be a separate species, so its status is not clear-cut. jimfbleak 20:08, 24 September 2006 (UTC)
"F. p. ernesti — is found in New Zealand and is non-migratory" This statement is incorrect. The peregrine falcon does not maintain a range within New Zealand. The only falcon native to New Zealand is the New Zealand falcon (Falco novaeseelandiae). The black falcon (Falco subniger), an Australian resident, has been observed on one occasion in New Zealand, and was believed to be a vagrant from Australia. The Nankeen kestrel (Falco cenchroides) is the only other falcon species observed in New Zealand. These kestrels are generally considered to be vagrants, and are uncommon to rare.

[edit] Heart Rate
Could someone verify the falcon's heart rate? Its really high at 600-900 bps. I think it's closer to 250. --Arcette 03:01, 19 December 2006 (UTC)
- Edit I changed it to the correct 268
[edit] Perigrine lungs
These two sentences confused me, and need clarifying
"The respiratory system is also unique; the Peregrine Falcon maintains a one-way flow of air so that it can breathe while flying. This system is much more efficient than the more common two-way flow of air. "
Does this refer to the continous flow of oxygenated air over the lungs that birds maintain using their airsacs? If so it is not unique to the perigrine falcon but is common to all birds. Or is there something particually unique about perigrine falcons lungs compared with other birds? Furthmore, I would be surprised if other birds (and bats) could not breathe while flying. Could someone who knows more about perigrine falcons please clarify this issue.
- The whole part concerning physiology is obvious nonsense and should be removed. Peregrines do not differ in this aspect from any other bird of prey. Any claim for such differences should be substantiated with scientific sources. Accipiter2 21:53, 20 January 2007 (UTC)
[edit] falcons
i love falcoms they are amazing —The preceding unsigned comment was added by 68.108.20.184 (talk) 01:33, 22 February 2007 (UTC).
[edit] "air intake?"
- At this speed, the air intake is powerful enough to burst the lungs of the bird but the curved cones around its nose divert enough air from the lungs to keep the bird from being injured.
I removed the above because it is nonsense, akin to saying "if the bird had a scoop shaped face, the pressure in it's lungs would increase". This is true of any animal that moves, it is not particular to the Peregrine and it is not remarkable.
If anyone can cite a reference which states how the adaptions of this bird are exceptional in scientific language with reference to the aerodynamic pressure around the shape of its body in a dive, then please rephrase the above to make it mean something.
