Talk:Bornean orangutan

Behavior

I removed the following:

The reason they are more solitary is because they are much more widespread than sumutram orangutans. On sumutra the orangs have to form bonds or else there would be numerous fights for space.

Are they more solitary because they are more widespread, or is the opposte true? - UtherSRG (talk) 19:04, 25 August 2006 (UTC)

sub species

Having taken the photo illustrating this article myself in the Sumatran rain forest it is a fair bet that this animal is actually a Sumatran Orang. Whether or not anyone will be able to tell the difference is a different matter! Dave —The preceding unsigned comment was added by 62.6.139.11 (talk • contribs) .

Thanks Dave. I've removed it. - UtherSRG (talk) 11:16, 5 September 2006 (UTC)

Social behaviour

"The Bornean Orangutan is more solitary than the Sumatran Orangutan. Two or three orangutans that have overlapping territories may interact for small periods of time. Males and females generally come together only to mate."

Because orangutans have often been observed wandering about on themselves, they have been regarded as solitary animals for a long time. Due to this assumption, at many zoos they have lived/live alone which usually led/leads to great loneliness and suffering for the animals.

As recent studies have revealed (like the observations of Willie Smits, founder of the Borneo Orangutan Survival Foundation), orangutans do enjoy the company of members of their own kind.

It is assumed that their relatively often solitary travelling is due to a shortage of sufficient food in the rainforests on Borneo and Sumatra. If they travelled in larger groups, the chances that the found food would be enough for every member would be rather small.

But it has been discovered that when there is enough food for several individuals in one place (like when a great fig tree is bearing fruit), many orangutans gather together and prove to be very sociable (playing, communicating, ...).

Averaged, there are more fruits for the orangutans growing in the rainforests on Sumatra than on Borneo (except for the years when many trees on Borneo are bearing fruit at the same time).

Besides, there are also mothers with their children, who were seen, travelling in the company of a few younger males. The risk that they ate so much that there would not be enough left for the mother is not that high. Also young males without their own territory have been watched wandering together.

Actually all versions of forming groups have been observed so far, except for two dominant males due to them being territory.

Taxonomy

Ref 6 of the article was a BBC News report on an article in Nature, which is actually freely available on the web, so I've changed the reference to point directly to it. The article in Nature appears to contradict the statement "The two species of orangutan are more distantly related than the common chimpanzee and the bonobo are", so I've deleted that.

The statement in the last sentence - "the name morio, as well as various junior synonyms that have been suggested, have been considered likely to all be junior synonyms of the population listed as pygmaeus in the above, thus leaving the taxon found in East Kalimantan and Sabah unnamed" - seems to me not to be what the reference (Bradon-Jones) is saying. It appears rather to be starting from the position that the Sabah population was not recognised as a taxon at that time, proposing that it should be recognised (the "B" annotation), and arguing that morio would not be the right name to apply to it. Or have I misread it? --Stfg (talk) 10:32, 9 April 2011 (UTC)

Reference to Rise of the Planet of the Apes

"It is also the type of Orangutan that can sign with Caesar in "Rise of the Planet of the Apes."" I really don't think this is relevant, especially not enough so to be in the first paragraph. Also, it doesn't even contain a link to the movie. If someone is willing to put in some sort of "Bornean orangutans in popular culture" section (though preferably a broader section like "Relationship with humans") then that is where this information belongs; however, until then it will remain removed it.

Copyright issues

It seems like a lot of the information added by User:Workmagr has copyright issues as it closely paraphrases this page. Jack (talk) 20:04, 19 March 2012 (UTC)

it should be specified flanges are a male exclusive trait 161.51.76.215 (talk) 09:06, 15 January 2024 (UTC)

 Not done: First, you didn't form your request as "change X to Y". Second, the "Physical description" section talks about how the flanges are on both males and females, but that they are larger on males, so your information is not accurate. - UtherSRG (talk) 12:14, 15 January 2024 (UTC)

161.51.76.215 (talk) 08:55, 14 February 2024 (UTC) please change the size and weight it displays false information with bornean orangutan males can easily reach 150-170 centimeters and 100-150 kilos yet it says orangutans are only 137 centimeters and 50-100 kilos i would not like any missinformation about orangutans to be spread

 Not done: please provide reliable sources that support the change you want to be made. UtherSRG (talk) 12:56, 14 February 2024 (UTC)
