Mangoes not Mongoes?
These beautiful creatures eat beans? Perhaps they eat fruit... —Preceding unsigned comment added by 220.239.212.68 (talk) 20:47, August 27, 2007 (UTC)

Source for Size/Weight
In the introduction, it lists that this species is smaller than P.Pygmaeus, however gives conflicting seemingly incorrect data, going so far to list that females are 3m (9.8ft) tall. Can we get this corrected and a reliable source? Kurtto (talk) 13:13, 19 January 2009 (UTC)

[Wrinsma] I have removed the part "and smaller" in the second sentence. There was no reference for this. As far as I know this has never been proven, in fact Wich et al. (2009) states that they are of equal size. — Preceding unsigned comment added by Wrinsma (talk • contribs) 09:28, 9 January 2012 (UTC)

orangutan rape
No source for this - I'll delete in a few weeks unless someone can find one. —Preceding unsigned comment added by 86.142.182.134 (talk) 00:31, 17 December 2010 (UTC)
 * Seems to be a controversial issue, with different views on whether is appropriate or not to label certain orangutan sexual behaviour as "forcible copulation" or "rape". --Elekhh (talk) 03:03, 17 December 2010 (UTC)
 * Good reference, and since it explicitly states "rape doesn't fit the scientific evidence" (and explains why), I've removed the sentence. Stfg (talk) 10:26, 28 January 2011 (UTC)
 * Given how much bigger than females even young males are, it is hardly obvious why females 'are easily capable of fending them off'. The current wording is saying they don't get pregnant from unwanted mating from junior-adult males, which suggests those males are capable of overpowering them, and doing so. Yet it then goes on to say they can fend them off. Overagainst (talk) 11:12, 20 September 2012 (UTC)

Orangutan menopause
Gina, a wild caught Sumatran orangutan at Durrell Wildlife Conservation Trust's HQ in Jersey underwent ovarian reserve testing, as well as physical examinations and an ultrasound investigation of her endometrium. She was confirmed by Obstetric Surgeon Mr. Neil MacLachlan to be in post-menopausal condition. The procedures and results were televised on an episode of Channel 4's series. A paper is currently in draft. http://www.durrell.org/closer/.Unluckyfriedviking (talk) 12:51, 4 November 2014 (UTC)

Lead images
Here is my "picky" edit of the day. I think when placed together the two lead images might be a little misleading. The text states the female is smaller, but when first looking at the images, the reader could gain the impression the female is larger. I will look for other images and ask for comments. I will also try to find a portrait which shows the enlarged cheeks of the male.__DrChrissy (talk) 13:06, 18 March 2015 (UTC)

Precision
Unfortunately, this article is full of minor contradictions and ambiguities caused in part by poor English grammar. In the photo of an 'orangutan and human', precision requires identification of which is which! 92.30.37.168 (talk) 11:36, 22 March 2023 (UTC)
 * If you find grammar errors, please correct them. And no, the photo really doesn't need a different caption. - UtherSRG (talk) 13:07, 22 March 2023 (UTC)

Hype and misinformation over 'medicinal' leaves healing a skin wound
This edit was justified to cool down the misinformation over F. tinctoria having a host of medicinal properties (it has none proven by any reputable medical source; WP:MEDRS), and the highly exaggerated, delirious discussion about the plant's supposed diverse clinical properties in this report by primatologists who were out of their field conjecturing about medicines.

The authors describe the orangutan "chewing the leaves without swallowing them and using his fingers to apply the plant juice from his mouth directly onto his facial wound." They do not mention the conspicuous presence in the "juice" of saliva, which really does have "antimicrobial" properties, enzymes, epidermal growth factor, and other potential 'healing' agents, which wild animals typically use to lick skin wounds. Lab research indicates saliva contains numerous compounds possibly supplying all the agents needed to heal the orangutan's wound. Zefr (talk) 20:56, 3 May 2024 (UTC)

Life cycle: the standard male, the invisible female
The article on Sumatran orangutans says both "At 8 years of age, female orangutans are considered fully developed and begin to have offspring of their own. Males, however, enter a stage called sub-adulthood. This stage lasts from 8 to around 13 or 15 years..." and "The average of the first reproduction of P. abelii is around 15.4 years old." Therefore, I conclude that the third sentence applies only to _male_ orangutans and will insert that modifier. Monado (talk) 03:23, 4 July 2024 (UTC)
