Chester Zoo sumartran orangutans

"Oscar" died in 1999 at Liberec Zoo, "Ramona" at Peaugres in 1997. They never got to know their grandchildren.

"Dunja", half-sister of "Ramona", lived to see three grandchildren and one great-grandchild at Leipzig until she died in october 2009.
 
How does this compare to Orangs held by other collections do you know?

I think Perth where Puluh's mother lives have had similar success with Sumatrans. They have also returned two of their Sumatran orangs to Sumatra, one a few years ago and one very recently.

Perth have bred a large number of Sumatran Orangutans over the years- more than Chester. They are a complex family and Puluh has several sisters and brothers in Australia. I think the two that have been released will also be related to him in some way.

His mother Puan, if she is still alive, is (or was, if dead now) one of the oldest Orangutans in the world.
 
Oh wow yes of course Gt Grandsires is impressive - I wonder if there would be any recognition between them if they met up again after being apart - they are sentient great apes so I'd expect some really seen as how they interact with regular visitors?
 
keep an eye out you experts as I want to know about the Bornean Orangs too - will start a thread!
I'm in learning mode today!!
 
so when was Puluh born (or how old is he) and where did he come from, or more accurately where was he born and when did he arrive at chester and where from?

God I feel like a school teacher asking a top streamed class questions!
 
Perth bred 19 Sumatran-Orang-Utans, 14 achieved adulthood. The most successful breeder in the world is Dresden. They bred 29 Orang-Utan, 20 achieved adulthood.

Puluh - Born in Perth 23 Sep 1987
Transferred to Chester 15 Dec 1996

If you archive Z magazine (of course you do) there's a really nice thing about the orangs from early last year.
 
Puluh (m) born 23/09/87 at Perth
Emma (f) born 13/11/87 at Chester
Subis (f) born 30/11/86 at Chester
Kirana (f) born 03/02/09 at Chester to Subis and Puluh
Indah (f) born ??/03/08 at Chester to Emma and Puluh

That is all I know.
 
to my shame mine are scattered about the house in a very unachived fashion!!
Thanks for all of the info guys - now I need you to let me into the secret of how to identify them when I see them.
Obviously the Adult males are easy as they tend to look like walking carpets!!

Emma has a more 'bluey' face - is that right?

Emma has a rounder face, Subis, deep set eyes..

And Subis has a missing finger on her right hand..

I think Chester have probably bred(successfully) the most Sumatrans in the UK with Jersey(okay- not UK!;)) in 2nd place. But they are still way behind a lot of other continental Zoo groups of Sumatran orangs which have very impressive breeding records-Dresden,Frankfurt, Berlin, Heidleberg, Zurich to name a few(+ Perth in Australia).

I have been to Perth but it was after Puluh was already at Chester. Several of his sisters are still there and also his mother Puan, who had a five year old baby(fathered by a different male HsingHsing, after Puloh's father Atjeh, died.) Puan was a small, dark-faced female, a bit like Jersey's 'Gina'.

Perth Zoo have in the past published papers indicating there is more than one 'type' of Sumatran orangutan- smaller, darker ones and larger, lighter-colored ones. Connected with this is (supposedly) whether or not they have nails on the hallux(big toe) of their feet.

Puluh's father 'Atjeh' was supposedly of the other 'lighter' type of Sumatran but he was already dead, so I never saw him. So Puluh may be a x between the two types(if you want to believe Perth's theories, that is.) Anybody want to check his toenails?;)

Isn't it mainly down to how many they keep? The two females are going as fast as they can - for females raising their own babies. Utara was quite young when Indah was born.

Some of the European Zoos have been breeding Sumatran Orangutans a lot longer than Chester- since the 1950's and 60's and even earlier than that, which is why they have even bigger 'dynasties' and some do have more breeding females also.

Ema and Subis at Chester do seem to be breeding very rapidly with quite short birth intervals- I don't know any reason why that should be. I also don't know if Chester plan to continue breeding from them unabated, I guess it depends on what is recommended by the EEP studbook holders, both for genetic considerations and also for placing any surplus young in other Zoos.

But it would be nice to see(eventually) some relocations of Sumatrans from Europe perhaps, along the lines Perth have now done. Perhaps such are planned eventually, I don't know.
