The benefit of splitting one subspecies as a separate article is negligible. Apart from the description the only way in which it differs is in a bigger cultural element, which could be easily included in the main species article. Shyamal (talk) 07:20, 15 April 2014 (UTC)

389 km/h !!!!!
[edit]I don't understand why are here accepted jokes such a '389km/h' launched in tv programs. — Preceding unsigned comment added by 89.180.198.15 (talk) 13:59, 3 November 2016 (UTC)
- It's not a joke, it's according to the cited source. 242 mph = 389 km/h (largely due to free fall acceleration, I think). Brandmeistertalk 14:09, 3 November 2016 (UTC)
- If it is no scientific, it is a fraudulent JOKE, of course very welcome in TV programs. — Preceding unsigned comment added by 93.102.119.216 (talk) 14:17, 26 January 2017 (UTC)
- It is scientific, not fraudulent, not a joke. It's been measured. So don't troll. -- 184.189.217.210 (talk) 06:37, 18 August 2017 (UTC)

Possible resource
[edit]Just became aware of this paper Intraspecific evolutionary relationships among peregrine falcons in western North American high latitudes that may be of some use here. Beeblebrox (talk) 19:59, 7 February 2019 (UTC)
Prairie-Peregrine-Hierofalcon
[edit]The Prairie falcon can be(?) closer to the Peregrine than to the Hierofalcons, but the Peregrine is closer to the Hierofalcons than to the Prairie falcon (see https://www.researchgate.net/publication/331118392_Phylogeny_of_Falconidae_and_phylogeography_of_Peregrine_Falcons and https://sciendo.com/downloadpdf/journals/orhu/26/2/article-p27.xml).83.132.96.185 (talk) 23:24, 21 August 2021 (UTC)
Wrong image
[edit]The first image is NOT of a peregrine falcon.
Fastest visual processing claim was wrong
[edit]The introduction previously said "According to one study, it has the fastest visual processing speed of any animal tested so far, and can register discrete changes up to 129 Hz", citing a News Nation article. However, their source is this study, which doesn't say that at all. They only measured 3 species of falcons, and found the peregrine falcon to have the fastest flicker fusion frequency of those three species. They then compared those numbers to others in the ornithology literature, where several smaller birds had even faster vision (see figure 3 for example), including 138.2 Hz for the pied flycatcher. They note that generally smaller animals and animals with higher metabolic rate have faster vision. According to Vogel 1956, houseflies have a flicker fusion frequency around 270 Hz, much higher than the peregrine falcon. I have therefore removed this claim and reworded the section.

Possible additional information about eggs?
[edit]Watching the Berkeley peregrines with fascination, but I wanted to know two facts. What are the typical period of laying of eggs (time from 1st to last) , and what is the typical period of hatching (time from 1st to last). Hopefully someone can access that information or point me to it. I'll be happy to add it to the article. Bastique ☎ call me! 17:28, 9 May 2022 (UTC)
Spoken article
[edit]I've decided to record a spoken article of this page. Bastique ☎ call me! 19:32, 9 May 2022 (UTC)
240, not 200.
[edit]The information on the peregrine falcon says that they can stoop at 200 miles per hour. I learned the fastest speed recorded was 242. Can you please change it? EAGLITIZED (talk) 00:36, 28 December 2023 (UTC)
- Do you have a WP:SOURCE? Mr Fink (talk) 01:46, 28 December 2023 (UTC)
- The article already mentions that 242 mph recording, both in the main text and the lede. The general estimate of over 200mph is stated and then recording of the higher value is mentioned in both places, with references. — Jts1882 | talk 07:26, 28 December 2023 (UTC)
