Agree with you on the chimps grantsmb.
For orangutans, if there are young and juvenile, they can be extremely playful and are no less active than other primates. They have boundless energy especially if enough of them are around to form a playgroup of sorts. The older ones are more laid back though.
Besides Siamangs, Orangs have been mixed with Asian otters here in Singapore as well as in Germany (Tierpark) as far as i know. Orangs may be the most placid of the great apes but they're still exceedingly strong and i've seen one of our orangs pick up and fling a poor terrapin with malicious force. Thankfully the terrapin landed in the moat and was unhurt.
Orangs are real smart, one at the Toronto zoo used to pick the lock of the door in its exhibit and then go and sit up on the top part of the roof every day, the keepers at first could not work out how the Orang could open the door as they could not find any thing that could be used to do that so one day a keeper stayed just out of sight watching to see what was going on, what the keeper saw really surprised them as soon as the Orang thought it was clear he got a bit of wire ( i think it was a paper clip) which he kepted UNDER his top lip all day and jiggled the lock untill open, How start is that!.
Puluh at Chester has escaped onto the roof several times.

Puluh has produced 2 other young with another female but I don't know her name it might be Emma
Chester has 3 male and 3 female sumatran orangs. One of the males is Puluh, 2 of the females are emma and Subis. In 2005 Subis gave birth to budi and Emma Gave birth to Utara.One of these young females must have moved on or died.The other 2 males must be their previous young.
Well I think that's right?!?
The first two babies of Emma & Subis were one male and one female. One of these may have gone elsewhere, or one of the two newer babies(Budi & Utara) could have died... These would have to be either two males, or one of each sex, depending on whether the older female young is still there or not..
The babies born in 2005 would not have been sent elswewhere(far too young) but one might have died..
