(Unsigned comment by 202.76.170.19
I have removed the following claims, which are inherently implausible, and for which I have found no evidence in the scientific literature or via Google. If they are reinserted, they should be accompanied by references to authoritative sources:
Thanks Seglea: I'd confirm all those claims are ridiculous. These are not intelligent animals, far less so than rats and dogs. Marsupials have very small brains and occupy very narrow ecological environments where not much intelligence/cunning is required for survival. The koala is the prime example of this kind of species in its niche (eats one things, sleeps all day, has a tiny brain, moves slow etc.). — Preceding unsigned comment added by 120.148.2.96 ( talk) 12:56, 10 January 2012 (UTC)
I have again removed the following, which was reinserted by an anonymous user:
The claims you removed are quite baseless, Seglea, as you have gathered for yourself. Thanks for cleaning the article up. Tannin 5 July 2005 12:56 (UTC)
Judging by the comments already removed from this article, someone has been pushing some laughable 'possum propaganda.' Anyone working on improving this page should be wary of further additions of this type because there is nothing remarkable about the brushtail in comparison to other possums/animals. They are certainly no more complex than rats (less so, rather) and are not commonly known for being especially socially or intellectually advanced. I would suggest also removing the section about them having an intelligence comparable to a dog (and the statements that follow about them learning tricks), as this sounds to me like further nonsense and unsurprisingly it's not referenced.

Sorry, but in my experience as an arbourist I can assure you that Brushtails do eat eucalyptus leaves. In Melbourne it is common to see Eucalypts (particularly mallee and corymbia groups) stripped bare by brushtails. I've seen numerous otherwise healthy park trees die from brushtail damage. We have to put guards made from PVC or sheet steel around the trunks to protect them. I'll try and remember to get a photo next time I'm out. njh 04:40, 28 July 2005 (UTC)
Just to confirm your comments NathanHurst, brushtail possums are enormously destructive of trees, particularly in overpopulated locations like Australia's cities (where the concentration is 10x that of the bush). Exotics like elms suffer the most, with many trees destroyed. PVC tubing is very common around trees in parks now.
Like other marsupials, brushtail possums have small brains as a percentage of body mass. While they do make a variety of noises (some bizarre, like the asthma-like breathing), in no way could they claim to have a 'vocabulary'.
Is there a reference for the information about their social behaviour? It is true that the possums where I live seem to make up a colony, and that the 'top' possum is a female– but most sources say they are solitary! Could this all have been inserted by the person responsible for the hoax about tools, language and military uses (see above)? Dawnfire 04:08, 26 June 2006 (UTC)
Oh– and interbreeding with the short-eared possum. First I heard of that! Dawnfire 08:15, 16 July 2006 (UTC)
I have removed the unverified info on social behaviour and replaced it with: "Socially they may be solitary or they may form small groups which share territory." Likewise that on interbreeding.
If there is a reliable source for this, by all means replace the information and this time STATE WHERE IT COMES FROM! Dawnfire 08:23, 16 July 2006 (UTC)
All research reports them as being solitary animals, with get-togethers rare except in cities where they may compete for food. They usually just ignore each other, or engage in scrapping (which can be quite violent). I suspect very high mortality rates the juvenile males experience may be because they don't 'inherit' a drey and appear to 'wander' more in their early months. I read a journal article that suggested that when overpopulation occurs (eg. in Australian cities, where they exist at 10x the concentration of normal rural settings), they give birth to more males - I'm not sure what the reason for this is, though the evolutionary reasons would be intriguing. I don't believe there is any evidence for them forming groups of any kind in a natural setting, but will leave the social behaviour section alone until someone can confirm that's the case. While they don't form groups, they do seem to tolerate others living in close proximity in the cities, as long as there's a constant supply of food. They do appear to opportunistically take over each others dreys though given a chance, and people who have installed possum boxes confirm there can be endless fights over who owns the drey, with possums coming and going. Again, this might be behaviour seen in city-based overpopulation settings only. — Preceding unsigned comment added by 120.148.2.96 ( talk) 12:50, 10 January 2012 (UTC)

I took this unsourced statement out - it was added by an IP on 13 Jan 2007 and seems a bit dodgy: "They are highly inquisitive and live in troupes of about a dozen individuals with a complex social structure not dissimilar from wolves and primates." Kāhuroa ( talk) 18:22, 10 June 2008 (UTC)

Although i do not want to argue about at least some of the removals, nor my not referenced, observtional addition being removed, i would disagree strongly about Seglea and Underspanky, or others claiming that they are not intelligent.
I should not have to say, that Intelligence is a on a RELATIVE SCALE - what is intelligent for an ant, is vastly more intelligent than what a fungus can do... whereas both are relatively limited although perhaps/less complex of timing/mechanisms... than what we can do,.. so ;
when you assess something that is in the middle, soto speak, of simple to complex organisms, marginal differences are actually quite a lot, in terms of a particular species importance - especially if the species, like a bee, or possums, are a part of reproduction cycles, or in the case of SOME possums in my exp, active MAINTAINERS of some of the trees they live in / get food from.
The fact that they can be a pest, should NOT somehow be used as a claim to justifying calling a relativly intelligent animal UNintelligent.
only a few days ago, one indicated to me that my garden arch was needing repair, in a intelligent, cooperative way - you also said, Seglea/whoever,.. on par with/like dogs -
dogs are one of the most intelligent, actually - but NOR are dogs and rats comparable, Underspanky - i've done enough Animal-Psychology, to know - while most rats might be able to understand that some things it can get through to get into a house, and others cannot, and to actively remember and identify the differences ( a grill compared to a hinge, a scratched-hole, compared to a open plug-fitting, yet to've been closed up, etc )... dogs (bred, i mean) have good social adaption/imitation memories and learning-centre adaptive traits... that doesn't mean that EVERY one you meet, will be lassie...
but it does mean that when a rat might have an oppertunity to adapt to a social need, that i cannot with anywhere near as good a range of COGNITION OF NEED, as dogs.
They have mostly(if not completely) more internally-driven instincts, they will socially adapt for their OWN children, or at a low level of immediate need and organisation FOR, needs...
...but they do not have the kinds of dream/imagination social capacities of dogs, at a higher level of emotional awareness, or similar - do not value the INDIRECT effects, when identifying emotion - if i make my owner happy, them BEING happy, will affect others in a way i want, rather than them being angry/demanding... or ... my owner who puts me in pit-fights, is in a apathetic, shocked, emotionally-sensitive state, after losing one of their own children... ill be physically playful and alert, with them, to SEEM like im still able to do what i need to be able to, for them to continue to want to keep me - if they think i'm not still a ferocious fighter, he might get rid of me... etc.
THAT kind of REASONING, is something well and truly established, with dogs.
rats? no, Possums have PHYSICAL APPEARANCES a little like rats, and people often cannot be BOTHERED LEARNING or observing the differences.
you have grouped both together, when they should be quite far apart.
As i said at the start of my criticism, when youre NOT starting from either end of the scale... humans are definately at one end...
then SEEMINGLY insignificant differences, are actually a LOT.
im saying this because the co-operative help (drawing my attention to a broken garden-arch) i received from a possum not two nights ago, says to me...
this animal could understand REPAIRS... and the oppertunity if not also, need, to report them.
yes, it would be in their interest, i would not deny that,..
...but that would not detract from whether or not it is intelligent, to do so.
quite the opposite - doing things that is in your interests, is a big part of what being intelligent, is all about.
at least when talking about it in biology generally - abstract arts / creation, obviously not... but would that be a fair comparison / quesiton ?
of course not...
being able to THINK a problem out, is definately a sign of intelligence, whether you like them or not. Same goes for anyone else reading this and wanting to compare gross differences, for a marginal-difference question.
i don't USUALLY care about marginal differences either! and if i was in NZ , i could happily munch down on a Possum Kebab!
But that does NOT mean, i would say they are not intelligent - i happily chow down on pig, cow, and i would a brumbies, if it was in the supermarket, WHILE STILL CALLING THEM, intelligent.
mmmm, intelligence, delicious! NZ, yes, but not here - here they are a valuable animal, in terms of the reproductive chain, food chain, and topsoil redistribution dynamics, as well as a few other things, like having a place in Aboriginal culture / sky-myth-methaphor, etc.
The intelligence question should not be acted upon in gross experience of DOMESITCATED v non-domesticated.
People often find criticisms in WILD creatures, compared to under our control ones, rather than sticking to the question impartially.
communicating to me to make me aware of a repair that needed doing, is DEFINATELY intelligent in my book.

Just removed this. Certainly OR ("original research"), and very close to a rant. More that that it is unclear what the point(s) is/are - and caps DON'T help. - Snori ( talk) 23:08, 27 December 2017 (UTC)
I'm not an expert on wiki or possums, so I won't make any changes to the page. I'll leave that to more qualified people.
The image labelled "Dentition of a common brushtail possum" File:Animaldentition_trichosurusvulpecula.png looks nothing like the teeth in the image labelled "Skull of a common brushtail possum" File:Trichosurus_vulpecula_02_MWNH_929.JPG nor those shown at https://www.bien.org.au/wp-content/uploads/2017/04/Skulls-of-Tasmania-Rainbird.pdf page 29.
The "Dentition of a common brushtail possum" image contains the words "Sooty Tapoa". Googling this results in various versions of poorly hand-drawn images dating from 1839 and 1856 - this image is one of them.
Could I suggest that this image be replaced with another, eg https://www.bien.org.au/wp-content/uploads/2017/04/Skulls-of-Tasmania-Rainbird.pdf An Illustrated Key to the Skulls of the Mammals in Tasmania R.
