Poor choice of words
Found this little gem of poor phrasing in the article.
"These bacteria are hungry for every molecule of nitrogen and phosporous they can grab. In this way, these and other nutrients are fixed into the beaver pond and the surrounding ecology, and are removed from the stream."
While it may be easily understandable. The suggestion of 'bacteria' becoming hungry or 'grab' nitrogen or phosporous compounds is simply un-encyclopedic.
I'm going ahead with a few minor edits. If the community has serious objections just revert.

Beaver Diet?
There seems to be no information on the diet of beavers in the article.
Well, they are completely herbivorous. Dora Nichov 14:07, 30 October 2006 (UTC)
...whatever....
I have seen them eating Sword Ferns (native) and Himilaian Black Berry(introduced) locally in British Columbia, Canada.
Breath?
Question: Does anyone know how long a beaver can hold it's breath? I have heard that they can be underwater for 30 minutes...
One of my books says five minutes...61.230.79.242 04:27, 24 June 2006 (UTC)
extinct giant beaver?
does anyone know if there is an article on the extinct giant beaver, Castoroides ohioensis, fossils of which have been found in North America? If not, I would be interested in integrating some information here. a couple of quick google references: [1] [2] [3] [4] joe 134.174.153.43 20:17, 1 Feb 2005 (UTC)
Seems to be under Giant beaver Dmccabe 20:02, 18 March 2006
I have a question. For reasons of completeness, would it be acceptable to include the vulgar meaning that "beaver" has? If so, I'd propose the following:
In American slang, beaver is also one of the vulgar terms for the vulva.
Since no one objected (and I asked nicely), this has been inserted as of 5 November 2002. Stormwriter
User 64.229.0.199 edited the common name of the Castor canadensis to read as "North American Beaver" rather than "American Beaver". This is not supported by any of authority including Common Names of Mammals of the World by Wilson and Cole. Castor canadensis is the only beaver native to the Americas, therefore "North" is not needed. Dsmdgold 16:11, 28 Apr 2004 (UTC)
I was under the impression that beaver "houses" were actualy inside of the dams, and the entrance was underwater. Even if that isn't true, and houses are built somewhere else, it would be nice if someone could explain their living environment better in the article --Ignignot 16:53, Aug 26, 2004 (UTC)
- Good point. The beaver lodges are mound-shaped "piles" of twigs and branches that are within the impounded area, not in the dam. When the leaves are off the trees, I'll try to get a photo on one of them from around here. Shoulda thought of that.... Pollinator 20:40, Aug 26, 2004 (UTC)

Article's state
This article seems to be in a bit of a mess, with the old Britannica text separate; as well, i just noticed (as it had not been crosslinked!) that there is an article for the American Beaver, which covers much of the same material. I'm not sure of the best course from here, but please keep this in mind... Radagast 03:57, Dec 16, 2004 (UTC)
Also, I think that the article has very little material on the beaver life cycle until the old Britannica text.
dams
I read a page -- elsewhere -- about the accidental introduction of North American beavers to Europe. It said that not only were North American beavers able to out-compete the already endangered European beavers, because they were larger, but they were much more of a nuisance because European beavers don't make dams.
- I don't know all the details, but the link here has a map showing North American beavers living in Finland. Not sure how/why they're there. http://www.scotsbeavers.org/Duncan%20Halley%20Report.html -- Funnyhat 22:11, 28 Mar 2005 (UTC)

- This is another story about the problems related to introducing animals in foreign land (Okay, foreign to the animal in question) Apparently, Argentina's military rulers introduced 50 beavers in Argentina for far, but their are currently a pain in the neck. The article is really fun to read, with comical quotes of unhappy dwellers like these "And I want to tell people in other countries, who say what a cute animal the beaver is, to think before introducing it. Its only natural predator is the bear. So they should have brought the bear too." [5]
In Anatomy
"Beavers have webbed hind-feet, and the claw of the second hind-toe double" Say what? What does that mean?

Question: Does anyone know how long a beaver can hold it's breath? I have heard that they can be underwater for 30 minutes...

Disputed tag in Dams section
In the dams section of the article, it states that beavers will build dams in the presence of sounds of running water alone. An anonymous editor changed the content to state the opposite. Does anyone have a source for this? My current approach was to revert changes by anonymous and tag the section as disputed pending a citation. --Aranae 03:51, 29 November 2005 (UTC)
- These sources all support the contention that the beavers are stimulated by the sound of running water to trigger damming behaviour. [6] [7] [8] [9] I couldn't find any reference to the view proposed by the anon editor, so I am removing the factual accuracy tag. AntiVan 00:03, 9 December 2005 (UTC)
- First hand experience shows that beavers being drawn to the sound of the tinyest trickle of running water has been correlated and verified. Egberts 07:21, 8 March 2006 (UTC)
Vandalism
After a slashdot reference somebody keeps adding the "Beavers explosively attack people with their menacing teeth. [citation needed] They are the most deadly animals alive" line. —The preceding unsigned comment was added by 84.163.222.96 (talk • contribs) 02:28, 31 January 2006.
It is more than one person, I did it once, and only once, cause it was funny. Before I could revert it, somone else had deleted it. Somone did it BEFORE the slashdot article was posted, which makes me wonder, are you all SURE that beavers dont explosively attack people? —The preceding unsigned comment was added by 66.92.66.31 (talk • contribs) 04:37, 31 January 2006.
The end of the "Danger signal" section looke as though it may be vandalism: "As well as Muskrats entering a beaver lodge, human entrance has been practiced as well. Sometimes a first nations member might use a beaver lodge as a hideout if being persued by an enemy tribe, or to sleep in whnen on an extended solo trip." Immediately preceding that "a slap of a beavers tail on land or water sounds similar to a shotgun fire." The shotgun line was added at about the same time and by the same ip as the other, less believable, note. I'm new to wikipedia; how should I proceed? -- thismatalk 19:55, 12 January 2007 (UTC)
Beaver Bites
The beaver attack is a reality but it is certainly not explosive. The difficulty is in securing documented sources over the net. This is basically a call to nature enthusiastics to recall articles from various conservations, games and fish magazines.
Scores of trappers have scars reflecting trapped but live beavers and have wisen up to this. Socialite newspapers have commented on scars displayed by trappers as a badge of honor. There is no telling how many trappers have died from this because of their solitary nature of the job.
As a geneologist, there are documented references of beaver attacks resulting in deaths. These sources are witnessed by me in two family bibles (of which I do not have access to anymore).
With my grandfather as a state game warden for Oscoda County, Michigan, he witness two separate attacks against loggers in Ludington county in the 1930s, of which one resulted in a death. Ludington Daily News newspaper has that obituary documented as well.
I also lived on Beaver Island (one of the galepago of islands in northern half of Lake Michigan) and witnessed an attack against an unwitted fawn.
For recent attacks, they have been mostly against dogs and young bears and ONE wolverine.
Egberts 05:30, 8 March 2006 (UTC)
- The pigdog link has a picture of a beaver with a rocket launcher, and links to an article that is no longer available, assuming it ever was. It is not a reputable source. I have no reason to doubt your family, but those sources, as you've pointed out, are not verifiable. I don't think it's necessary to have a source right away for every single thing on Wikipedia, but this issue needs a source because 1) the beaver attack thing has been going back and forth here for a while, with no one coming up with a verifiable reference, and 2) it is not obviously true. I've already reverted the beaver attack thing once today, so I won't revert it again right away, but please try to find a verifiable source if you want this to stay in the article. Thanks. --Allen 05:48, 8 March 2006 (UTC)

- Source:Reuters 2000 June 6 WINNIPEG, June 6 (Reuters) - A Canadian farm woman is still shaking after a crazed beaver attacked her two giant Newfoundland dogs named Bonnie and Billy, pinning them against a fence and savaging them. "It pinned them. I never though beavers were capable of that," Sam Pshyshlak told Reuters from her Manitoba farm 100 kilometres (60 miles) north of Winnipeg. "I've lost all respect for beavers. I never would have imagined this from a beaver," she said of the recent incident. She said the beaver "terrorized" her dogs, which weigh nearly 90 kilograms (200 pounds) each. "There was definitely something wrong with it," Pshyshlak said. The thick pelts of beavers were once Canada's main export and the flat-tailed animal has long occupied a place of honor on the country's five-cent coin. Most Canadians see them as cute and industrious but farmers often regard them as a nuisance for the dams they build and the flooding they cause. Pshyshlak said the animal that attacked her dogs weighed about 13.5 kilograms (30 pounds) and tore at Billy's leg and face. "In the shed, the whole floor was pooled with blood," she said. Pshyshlak said conservation authorities said they would try to trap the animal, although she said she hasn't seen hide nor hair of the beaver since the attack occurred. 06:46, 8 March 2006 (UTC) Egberts 06:49, 8 March 2006 (UTC)

- I have little doubt that a beaver could do some serious damage, and that it could even prove fatal if it hit you just right and you had no access to medical attention. I think the term "explosively attack" is really ridiculous. I'm not sure there needs to be much more then a note that beavers are sizeable mammals with a very powerful bite and have been known to injure people (if even that much). --Aranae 06:24, 8 March 2006 (UTC)
- More sources Friday June 1 8:52 AM ETHELSINKI (Reuters) - A Finnish wildlife lover survived unscathed after a beaver tried to sink its teeth into his neck as he tracked it along a remote river.
I thought it would be nice to see the beaver jump into a river so I followed it. Suddenly the beaver disappeared and next thing I knew it was hanging on my neck, Penti Jylha said Friday.
Experts say it is rare for beavers to attack people. Usually the shy beasts just escape when disturbed, or slap their tails on the ground if they feel threatened.
Thanks to the cold Finnish summer, Jylha was wearing heavy clothes which protected him from the beaver's long teeth.
When I managed to shake off the beaver it just stayed staring at me from a few meters away, he said. Egberts 07:45, 8 March 2006 (UTC)

- I reverted Egberts additions to the article just now before reading this discussion. I apologize for that. However, I think this issue is best discussed here until a consensus is reached on what content, if any, is added to the article. As Allen points out, this issue has a history. The Jama and EINet News Briefs seem to satisfy WP:RS, but do not support the added content. The Reuters citations support the content in part, but I don't know how to access Reuters. Presumably these were republished in newspapers where they might be more easily found? Unless beaver bites can be shown to be a significant public health problem, my view is the same as Aranae.

- To me, this issue has the flavor of an urban myth or bigfoot. I grew up near a beaver dam and I currently live near an urban park that contains a beaver population. I've never heard these stories before seeing them here. Moreover, I've never seen warning signs of the sort that are common in National Parks or urban areas where potentially dangerous wildlife are present.
If belief in beaver attacks is notable, it should be straightforward to find references that can be cited. The Reuters news articles are first person accounts with no indication that they were independently investigated. Such accounts are commonly cited as evidence for bigfoot. Game and fish magazines commonly publish stories that are not independently investigated, if I'm not mistaken.
However, unless references in reputable public health publications can be found, I don't think we can dignify this with more than a statement of the sort, "Some people think that Beaver attack people and other animals. No support for the view that this is a significant public health problem can be found in the public health literature. Persons should avoid any mammal exibiting aggressive or unusual behavior." The last sentence is from MMWR. 2002;51:481-482, reprinted by JAMA (citation above).
Upon reading Egberts text more closely, I find that I agree that the first paragraph of his addition is supported in part by the MMWR citation. However, the MMW article states, "rodents are not a wildlife reservoir for rabies virus and no rabies transmission from rodents to humans has been documented." Also, in 2001 in Florida, the Florida Dept. of Health found that samples from 124 racoons, 34 foxes, ... and one beaver tested positive for rabies. Unless this information is impugned, I don't think it is notable and should not be added to the article.
The MMWR article does suggest that rabies is found more often in beaver in eastern states other than Florida. That information, if reliably sourced, may be notable. My guess though is that rabies in beavers is a minor public health problem compared with rabies in racoons or foxes. Walter Siegmund (talk) 19:22, 8 March 2006 (UTC)

Suggested Beaver Bites excerpts
A ferocious beaver attack may be an indication of beavers with rabies. Unlike smaller rodents who die shortly after contracting the disease, beavers can survive long enough to act as a reservoir. In its usual non-infectionous state, a beaver rarely attacks beyond the one or two defensive bites. Observed beaver attacks also have been made against dogs (Seaman_(Newfoundland_dog)), young bears, wolverines, bobcats, rats and fawns.
Human deaths from beaver bites have been recorded as far back as 1642 in geneology archives and family bibles. It is difficult to assess the death rate by beaver bites toward trappers during the wilderness days due to their solitary nature of the job. This trend is inferred by trappers' permanent absense and later a grisly discovery due to a singular but mysterious animal bite by others. Most animal attack sessions by carnivores leave multiple bites, whereas beavers are herbivores and will bite once or twice to make a defensive point.
Today, increased public awareness, medical advancements (tourniquet, rabies shots) and diminished beaver population has greatly reduced this deadly trend to the last reported death by a Ludington Daily News obituary (Ludington,_Michigan) which occurred in 1933 against one unfortunate logger.
Deaths from beaver bites usually result by uncontrolled (but now rarely uncontrollable) bleeding. Egberts 17:19, 8 March 2006 (UTC)
Swedish grandmother hospitalised after beaver attack Wed Aug 8, 2007 10:01 AM ET
STOCKHOLM (AFP) - A grandmother taking a leisurely swim in a Swedish river ended up in the hospital after a beaver attacked her with its tail, regional newspaper Nerikes Allehanda reported Wednesday.
Police sources said it was the second time a beaver had attacked humans at the beach on the banks of the Bottenaa River, around 150 kilometres (93 miles) west of Stockholm, the newspaper reported.
"The beaver attacked the grandmother. She was seriously hit by the animal's tail and received a number of bites and scratches," an officer told the newspaper.
The authorities have decided to kill the dozen or so beavers living near the beach to eliminate any further risk to local bathers.

I'll let the main editors here decide if they can use this image. It was taken at Boyer Chute National Wildlife Refuge, November 2005.

It looks like it may have been taken very early or late in the day with very warm illuminate that perhaps the camera didn't correct properly.

I created a gallery page on commons for Castor organized by species, and added a commons tag to this article. A fresh look at the illustrations and layout might be in order. I think some of the commons images may be superior to those that are currently being used. Also, it might be good to discuss breaking the article into subarticles for C. fiber and C. canadensis at some point.

- Of course you are correct. I was misled by the extent of this article. I am more accustom to seeing abbreviated genus articles with most of the information in the species article.

LSE?
The American beaver is the emblem of the London School of Economics? Sounds, um, kind of unlikely at first hearing. Someone please confirm. — Haeleth Talk 23:41, 18 April 2006 (UTC)
Plagiarized from LSE website: http://www.lse.ac.uk/collections/LSEAnnualFund/beaversClub.htm "The Beaver's Club The idea of the School needing its own coat of arms first came up towards the end of the 1920s. A committee of 12 members including eight students was set up to search for 'the figure of some animal which would be emblematic of the work of the School'.
The committee decided on the beaver as in its view it is known for foresight, constructiveness and industrious behaviour. In 1925 a carved wooden beaver presented by four professors was officially named 'Felix Q' and enrolled as an honorary student. Since then the beaver has been one of the most well-loved characters among students at LSE, with the student newspaper pertinently named after him."

Lodges and Dams
Beavers do not live in their dams. They build a separate lodge -- either in a dome shape, made of mud and sticks, or dug into the bank of a river. Perhaps a heading just for beaver lodges could make this clearer.
That's true. Many people think they live in their dams, but no.61.230.79.242 04:27, 24 June 2006 (UTC)
Are they Fish? (Position of Catholic Church)
Not a big argument with the Catholic interpretation cited; but the sources appear very similar, are anecdotal, & not 'church' sources, whihc almost make one wonder whether this is a bit of urban Myth - does anyone have an actual edict/declaration/better source? (NOT arguing to chop this bit, just really curious as to the real source).Bridesmill 16:44, 5 May 2006 (UTC)

-
- Not the perfect source ;-) but it certainly adds credence to the story; mind, the comments of an 18th c author who appears to be somewhat strident in his views of catholics...to me the jury is still 'somewhat' out (but not enough to suggest deleting this just quite yet) thanks.Bridesmill 03:37, 6 May 2006 (UTC)
Why is this section still here? There's no reliable source for it, and last I checked they have something called a burden of proof that prevents you from asserting whatever you like.
EDIT: Here's why I assert the sources are not reliable:
5) - Cites Pehr Kalm, of whom I know little, but whose Wikipedia article suggests he's a fairly unreliable source on Catholic doctrine: born in Sweden to Finnish parents, the son of a Lutheran minister and himself a minister later in life, etc., etc. In fact, later in the writing cited he goes on to call the Catholic tradition of the fast basically hypocritical. This means the most reliable source on an apparent embarassing archaicism and abuse of church power, for those keeping score, is a Protestant lay clergyman and natural scientist in the middle of grinding an axe with the Catholic Church.
6) - A Catholic source containing no reference whatsoever to beavers.
7) - A simplistic, pedagogical website about beavers passing along the idea that the Church once decided the beaver a fish. In this story, it decides such on different grounds than Kalm would have us believe!
8) - A sports publication, again written with beavers in mind rather than Catholics. It calls the scaly tail and the swimming skills properties of the beaver that lead the Church to declare it a fish - repeating the reason given by 7) and adding a third. It also asserts, intriguingly, that the Catholic church still considers beavers a fish!
In short, source 6 is irrelevant; sources 5, 7, and 8 directly contradict each other in various ways; and each presents the idea that beavers used to be considered or are currently considered fish by the Catholic Church as beaver trivia; none claim to be experts on Catholic practices or history, merely on beavers.
The source I would give the most weight is 5), and it is, again, written by someone with such a clear contempt for the Catholic Church that accepting it on its face is unreasonable.
I sincerely apologize for spending three times as many words as exists in the section deleted explaining why it ought to remain so. Full disclosure: I am not a Catholic, but was raised one, and observe there to be a serious baseline anti-Catholic bias in a lot of anglophone scholarship. The Church has a lot of things wrong with it, but I'm not about to sit back and let pass the idea that among them is something as inexplicable and stupid as considering beavers fish.
ACK-47 01:08, 24 July 2006 (UTC)
Why do you consider these sources not acceptable? Regardless of the fact there is some bias, one has to assume that some fact-checking took place here, unless someone can show me some evidence that this is/was a hoax. The story is just too credible & well established; ideally, I would love to see a primary sosurce, but the secondary ones there are 'aren't as bad as a lot of WP & appear to meet WP:V.Bridesmill 01:18, 24 July 2006 (UTC)
- Urban legends tend to be well-established. As for 'credible', I hardly consider it credible: which story would you have me believe, the one that somehow Church scholars were convinced by an animal's tail that the animal was a fish, or that its tendency to spend time underwater made it a fish in spite of the fact it possessed, I don't know, fur, arms, legs all of that? It's a story that requires the highest officials of a church which was still very much a destination for the best minds of half of Europe to be absolute and peerless idiots. And on whose say-so? A Lutheran minister snidely dismissing an integral Catholic practice!
- In short, it's only 'credible' if you're willing to assign astounding stupidity to Catholics. I'm not, so I don't consider it credible. If you'd like, we could send an e-mail to the proper authorities and see if they do; the only problem is that the proper authorities probably take a long time responding and are fairly reticent about admitting past mistakes anyhow.
- ACK-47 01:40, 24 July 2006 (UTC)
I wouldn't call it stupidity. 300 years ago the world was a different place. Context & worldviews change. Quebecois source: Lacoursière, Jacques. Une histoire du Québec ISBN 2894480504 cites this dating back to Bishop Francoise de Laval, who asked the question of the Sorbonne in 1600something; unfortunately, book only available in French, will see if copy held at any local U's. Telequebec also aired a piece on this, http://video.telequebec.tv/catalogue/documents/GeoHist_009.pdf if you speak french (VHS 3 doc. 29) I can find nothing referring to this story as a hoax in Quebec websites.Bridesmill 02:18, 24 July 2006 (UTC)
- I'd quite appreciate it if you did. I'm just worried that the primary (english) sources thus far seem to trace back to something written in the 18th century - and certainly Catholic doctrine has known friendlier periods of Protestant scholarship.
- I wouldn't retain any serious objection to the inclusion of the section thus mentioned, I just want to make sure it checks out. (I'd consider a citation from de Leval a lot more illustrative than one from Kalm.)
- If you don't mind, I'm also going to clear out the irrelevant citations - leaving in #5 tentatively, because of the ones there it seems the most creidble - and until we've got information on de Leval's inquiry, maybe tag the section disputed.
- Thank you for your civility and cooperativeness. ACK-47 02:36, 24 July 2006 (UTC)

- See this site: [10]. The blogger (who does not seem to have any kind of anti-Catholic agenda at all) cites Davis's Moral & Pastoral Theology for the proposition that beavers are edible on Fridays during Lent. Davis apparently discusses the same passage from St. Thomas Aquinas's Summa Theologica that was one of the deleted footnotes. Moreover, I interpret this blogger's text (and the source he quotes) as authority that the Church still considers beavers to be other than meat for Lent purposes.

First, Kalm has no reason to lie. To make catholics look bad and silly, yes; but one does not achieve that by spouting easily refutable bold-faced lies. Second, the Summa explains clearly the logic used in reaching this decision and is thus if not a direct citation a useful explanatory footnote. Thirdly, An incorporated Zoo and credible sporting magazine are certainly more WP:V than the opinions of a university student. Fourthly, I have provided two additional references from a groupd which if anyhting by your logic should want to supress this little fact, or expose it for the hoax you seem to believe it is; and somehow that leads to summarily deleting refs and slapping a dispute tag up. Fifthly, if this was a hoax there should be at least some evidence of such, particularly in quebecois websites. Sixthly, I find your insinuation that those who believe this are stupid somewhat insulting, and somewhat narrow-minded. People believe all manner of things which n the clarity of wisdom and hindsight appear foolish.Bridesmill 13:43, 24 July 2006 (UTC)
- I assume that ACK-47 isn't intentionally being insulting. I'm Catholic myself--(not that I have any particular beaver-eating plans). Sometimes religious rules can draw distinctions on grounds that might appear arbitrary or silly to outsiders, like Kashrut or Halal distinctions, or Jehovah's Witnesses and blood transfusions. Even the United States Supreme Court has held that for some purposes, strict biological classifications must be set aside and other classifications adhered to. There's nothing per se silly or stupid about this.Spikebrennan 14:44, 24 July 2006 (UTC)
-
- No, I was not intentionally being insulting and I don't really grasp the need for the sudden change in tone. I deleted the references because they're poor references; a single reference is perfectly sufficient and adding more, dubious ones achieves nothing extra.
-
- 'Hoax' is entirely the wrong word. I never proposed it was a hoax; 'hoax' implies malice, something I don't think is present here. I claimed it seemed to be an urban legend to me. I certainly don't suspect Kalm would directly lie; my presumption was that, were he an unreliable source, he would be repeating something he had heard from another source and so on. Additionally, 'an incorporated Zoo and a credible sporting magazine' are just as succeptible to an (apparently common, as people who have never read the article have heard the same thing) urban legend as anyone else. Especially when it involves things outside of their actual ken (would we consider citing theologians on basketball minutiae?).
-
- I tagged it with a dispute because pending the new evidence you mentioned I continue to contest its accuracy. I trust that you do, in fact, have evidence that will prove it accurate; I just want to see that, OK? Presenting information without substantial proof is unacceptable. Please pardon my unwillingness to accept the word of a Lutheran minister known primarily as a naturist, a zoo, or a sporting magazine on a matter of Catholic doctrine.
-
- Frankly, the direct hostility of Wikipedians towards any kind of redaction is a little disturbing. I could come in with a dodgy reference and claim beavers and platypuses can interbreed and I doubt it'd be taken down for the better part of a month - yet I doubt the veracity of a stylistically ungainly addition (it's under its own section and is two sentences laden with half a dozen quotations) and within two days I've been reverted twice and had aspersions cast on my ability to edit Wikipedia because of my level of education.

- I think that perhaps the most interesting thing that I've learned through this whole discussion is not that "the Catholic Church thinks that the beaver is a fish", but (see the blog referenced in my comments above, which I believe is written by someone who seems to be somewhat of an armchair Catholic theologian, and who cites his sources) that this is an example of how the Catholic Church is capable of drawing technical distinctions with as much subtlety as Talmudic scholars. St. Thomas Aquinas's passage in Summa Theologica provides a rationale for drawing the meat/nonmeat line with land animals on one side, and non-land animals (such as fish and beavers) on the other side, and it appears from my citation above that the Church continues to adhere to this distinction. Perhaps this discussion could benefit from inviting contributors from Talk:Meat and Talk:Thomas Aquinas.Spikebrennan 14:43, 25 July 2006 (UTC)

I apologize if I came across a bit crass; but please check my contribs & you will see I do not fit into the category of the direct hostility of Wikipedians towards any kind of redaction , and you must admit that it's only 'credible' if you're willing to assign astounding stupidity to Catholics makes some not-so-subtle allegations about my scholarship. Please note also that I'm the user who questioned this to begin with. I tend to fly off the handle a bit when people make assumptions and based on a flaw throw the baby out with the bathwater. Your questioning of the issue is fully within your WP rights & indeed duties; if all this accomplished is to put the issue as a cultural anecdote in rather than its own section, this is probably a good thing.

- Well, can someone either come up with a better link that has Rome actually saying, "Beavers aren't really mammals, they are fish," or at least reword the paragraph to indicate that beaver meat is permitted to be eaten because the dividing line between what was permitted and not permitted during Lent was between land and water animals, or whatever the reason was? The way it reads now looks like the story that told about the State legislature that wanted to declare that "pi" was 3.
And no, I don't doubt that beaver is a permitted food, for whatever reason. Seal has been permitted during Lent in Newfoundland at least since my grandfather's day. --SigPig 15:52, 25 July 2006 (UTC)

Popular culture
On 28 June 2006, I moved the popular culture references in the Introduction to the Popular Culture section and removed the redundancies. 128.193.0.6 restored them to the Introduction. I think this is a bad idea since it gives undue emphasis to such usage in an article that is about an animal. In any case, this information need not appear twice. --Walter Siegmund (talk) 02:13, 18 July 2006 (UTC)
Another use of beaver in popular culture is within the phrase "split beaver", referring to the open female genitalia, especially when surrounded by pubic hair.
I corrected the meaning of the Algonquin word "amik" (the name of the Canadian Olympic mascot) to be "beaver" as opposed to "friend". I am not familiar with Algonquin, but the similarity to the Latin word for friend seemed weird, and the first couple sources I checked all said it means "beaver". Hope no one minds.

Agriculture
It seems to me that this is a clear example of agriculture by this rodent, creating a habitat to grow what they eat. I have heard of ants farming fungus, but this seems to rank up with using tools. If they build their homes in a way that creates a slow wetland, where the food they eat grows, they aren't just great engineers, but also farmers.
Conscious Planning?
The article currently states: "It is both the sound of water in motion and the current that stimulates the beavers to build."
This is proposing an unconscious stimulus-reaction mechanism. Is that supportable, versus the beaver noticing there's a leak in the dam and doing something about it?
--- Yes, there have actually been studies that have shown that beavers in dry pens have begun to build dams upon hearing recordings of flowing water, in a dry pen. However as far as the leaks go, thay always leak. It does not seem that the Beavers goal is to prevent total water stoppage, just enough to create their habitat. 67.142.130.45 04:44, 7 December 2006 (UTC)LorrinLR@aol.com

article from Beaver Control, some information able to be moved into Beaver?
Humans must continually search for effective methods to coexist in the natural environment our world presents. This is a huge concern as our population grows and our reliance on the earth to provide food and habitats for the people of the world to live in increases. There are many cultures of people and types of animals that must survive finding food and shelter. Beavers are just one example of this interaction. Beavers have to create a habitat to live in. This habitat can be found near creeks and streams or other bodies of water. Problems tends to arise when people live near these creeks and rivers where the beavers have worked to create the habitat they need to exist. When the beavers build dams, adjacent yards and fields can be effected by the altered levels of water.
Why they build the dams
Beavers build dams so they can safley travel in and out of their homes without being vulnerable to prey. These dams cause the water in the creeks and rivers to flood the surrounding area upstream from the beaver's dam. In order to prevent this flooding from happening some people take action into their own hands by killing or trapping the beavers. Others leave the beavers alone and let nature take its course.
I believe that with innovative ideas beavers and humans can coexist without conflict. Many naturalists want to attempt to restore streambeds to a condition that would naturally attract beavers. However, that change could create problems for the stream structure and the surrounding suburban areas. One idea, called a “beaver deceiver,” is described in “The Solutions to Beaver/Human Conflicts”. This method has been used for beaver-proofing parts of Vermont. This is a device that will maintain the level of water so the beaver's needs are met for its home and safety while not flooding the farmer’s crop fields or neighbor's back yards. This method permits the beaver to live in a healthy habitat while allowing crops to grow in adjacent fields.
What is a Beaver Deceiver
The Beaver Deceiver is made of cedar posts and wire fencing, consisting of 6-inch squares. These devices are intended to prevent the beavers from bringing large logs and sticks to build their dams and thus clog up waterways. Their suggestion is to put drainage pipes, better known as PVC pipes, throughout the middle of the dams so that the water keeps flowing through the dams. In addition to the PVC pipes, a fence or some sort of cover would need to be built so the beavers do not attempt to build around the drainage pipes which would clog the pipe. The one small drawback to this method is that it requires seasonal maintenance to unclog the pipes.
These devices can work for individual situations, but are not as effective on a large scale. Some people believe that the beaver deceiver is only a temporary fix and the adjacent areas will eventually be affected by beavers.
This method has been developed by researchers in an attempt to maintain the existing environment while allowing animals in nature to thrive. Each situation with beavers building dams is different which presents an opportunity for people to find other soultions to problems according to their own circumstances.

- Or the order rodentia the beaver is the second in point of size, the only species exceeding it being the Capibara (Hydrochoerus capivars) of South America. The American and European beaver constitute the only living representatives of the genus castor, and the difference between the two is so very slight as to be scarcely noticeable to any one but a scientist. Externally, except in point of size, the two species are practically identical, the American being slightly larger, but an examination of the skulls shows certain minor differences, chief of which is the slightly greater proportional length of the nasal bones and narrower skull of the European species (Castor fiber). Another less noticeable mark of distinction is that the castoreum obtained from the European species, especially those from Russia, is more valuable and contains a greater proportion of castorin resin and albumen. In point of age the beaver is evidently an animal of great antiquity, not only in its present form but the larger and extinct Trogontherium (of Europe) and the astoroides (of America), neither of which are believed to be the ancestors of the present-day species, as their fossilised remains have been found in the pliocene deposits in which were preserved the skeletons of the Mastodon and Mammoth, so that these animals lived during the tertiary period and from the evidence which nature thus preserved there is no reason to believe that the beaver, as we know them to-day, differs in any marked way from those of prehistoric ages. The earliest European Beaver was probably the chalicomys which has been found in the Miocene beds of the Continent. It was considerably smaller than the existing form and " differed from all living rodents in having a perforation of the lower end of the upper arm-bone or humérus " (Lydekker). The largest of the family was the Castoroides, whose skull was only about four inches less in length than that of a lion and was probably the largest of any of the rodents. The beaver, both American and European, had the largest range of any animal, those in Europe having existed all over Europe, including Great Britain (not Ireland) and Asia as far as the Euphrates. During the Pleistocene period they lived in Italy as far as Rome, while the American species ranged all over North America from the Arctic Sea to Mexico. At the present time the American beaver, Castor Canadeiisis, is chiefly restricted to the more northern portion of the Continent of North America ; none are found in the region of the great plains, nor in the more southerly and easterly parts. Practically speaking, their principal habitat is Canada, Colorado, South Dakota, New Mexico and Alaska.

- It is interesting to note that C. canadensis was also released in Europe. Two pairs released in Finland in 1937 multiplied successfully (Härkönen 1999). The species is outgrowing the autochthonous Castor fiber, maybe because C. canadensis uses resources more effectively, has bigger litter size and is more active in building dams and lodges (Nummi 2000). Due to damming, forest damage by flooding or higher water levels was observed, causing conflicts with the industrial forestry practised in this country (Härkönen 1999). Current strategies to control C. canadensis in Finland include hunting and, less effectively, destruction of dams. Specimens from Finland crossed the Russian (Nummi 2000) and Swedish (Kinzelbach and Sommer 2001) borders. In other European countries, C. canadensis was obviously less or not successful. Some American beavers were most probably among the specimens from Sweden released in Bavaria in 1970–1972, but C. canadensis constituted only 3% of ca 100 beavers found dead in Bavaria in the 1990s (Kinzelbach and Sommer 2001). Until 1988, 15 specimens of C. canadensis were released in the Danube river east of Vienna; but most probably, they perished (Schwab and Lutschinger 2001).

Castration
Various Indo-European cultures spanning to at least the 6th century BCE historically hunted beavers for oils produced from scent glands in their groin. A long-standing myth which goes back at least as far as [[Aesop]] is that a beaver, persued by hunters and unable to escape, will chew off its testicles and offer them to the hunter. This is the origin of the shared etymology of the [[latin]] castor (beaver) and [[castration]].
Can we confirm this? If not, maybe we ought to remove it, as weirdly plausible as it sounds. --P3d0 14:54, 16 March 2007 (UTC)
- Dictionary.com shows the etymology of both Castor and castrate. Interestingly enough, it looks like the Latin use of Castor was derived from the mythological hero/god involved in medicine and the use of castoreum in medicine. Castor was derived from the Greek Kastor which means "one who excels". Kastor is also Greek for beaver (due to their industriousness?). So the name came full circle. Presumably the Romans knew of this connection and that's probably part of the reason Castor started to take over for fiber as the Latin for beaver. Meanwhile castrate derives from Latin castrare which means to castrate. They may connect with another step or two further back in time. I think trying to see if the Greek root of the Latin castrare connects to beaver is needed. It would take more work than the online dictionary, though. --Aranae 16:00, 16 March 2007 (UTC)

As an alternative to this proposal, I would favor turning this article into a WP:DAB page, but it probably makes sense to discuss the genus here. Also, we need a place to discuss the extinct species, Trogontherium cuvieri, although it could be given its own article and linked from the DAB page. Walter Siegmund (talk) 17:44, 3 May 2007 (UTC)
- Oppose. Both proposals. Every genus (Castor), family (Castoridae), and species (C. canadensis and C. fiber) of mammal warrants an article page. Particularly something as well known as these animal. Walter, I'd encourage you to start a Trogontherium article if you have interest. --Aranae 05:26, 4 May 2007 (UTC)
- Oppose. Seeing as the American beaver is a different species than the European beaver they should be in two separate pages. Tkessler 02:53, 16 May 2007 (UTC)
Reintroduction and early conservation
The article mentions the early 19th century near elimination but does not mention anything about the reintroduction efforts and conservation. I remember reading an old US Geological Survey report from the early 1900's that mentions that the beaver was "of conservation concern" and that "re-introduction efforts continue throughout its historical range". Can anyone find other references to this? —Preceding unsigned comment added by 68.111.251.52 (talk) 02:18, 29 October 2007 (UTC)
They were totally gone from large portions of the range; not certain if numbers were back up to snuff by the 1940s certainly in Eastern Ontario they were 'gone' until the 60s-70s. Also a bit confused by the 'there were once 10x as many' - the current population requires serious control in absence of natural predation, and if there were 10x as many as there is now, there simply wouldn't be 'any' woodland left...I haven't the time 'right now' but will keep an eye out for any cites...Bridesmill 02:35, 29 October 2007 (UTC)
