I'm writing a book about an orangutan who was housed in zoo of Paris and is now in Apenheul zoological park, Apeldoorn, Wattana : C. Herzfeld, Wattana, Un orang-outan à Paris, Paris, Payot & Rivages - to published on October 2012 I'm writing a chapter about the orangutans housed in zoo. I saw that the Jakarta zoo has the highest amount of specimens (90 orangutans ?). I would like to know more about the orangutans (sex ratio, births, number of babys, children, juveniles, subadults, adults) and how it is possible that there are so much individuals. Are they rehabilitants or;;; ? Thank you very much for your valuable help... Chris Herzfeld
where on earth did you come across the figure of 90 orangutans at Jakarta?! I don't know what the number they do have is but there certainly aren't anywhere near that there, even if you combine the totals from the Ragunan Zoo and the Schmutzer Primate Centre.
I would be extremely surprised if they do have 90 orangutans there, but maybe they do. If you have seen the studbook then surely you must know the details (sex, age, etc) already?
in 2009 they had "almost fifty": Zoo News Digest: At Last! Action For The Orangutans At Ragunan Zoo in 2012 the number in this article is given as "over fifty" in the zoo and nineteen in the Schmutzer Primate Centre, which makes about seventy. Far higher than I would have thought!!! http://www.germancentre.co.id/en/germanews/103-visiting-obama-at-ragunan-save-the-orangutans
