When I visited on bank holiday Monday, he was pacing back and forth, into the corner, then back again up to the glass, but not settling by the window like he usually does.
Rather worryingly, on the Colchester Zoo facebook page, someone else mentioned that he'd seen him pacing 2 days before.
I spoke to one of the keepers (who seemed to be watching him) and she described him as unsettled, but didn't know why, though she did say he wasn't poorly.
I also asked about a companion for him. She said that this is definitely still on the cards though they're a little concerned that if they get an elderly female orang, they could find themselves in the current situation again (i.e. one orang on its own) when one of them dies. She did however say something along the lines of (can't remember her exact words) there being rumours of a pregnant female, though she countered that with the obvious fact that most zoos wouldn't want to relinquish a pregnant female ....... so don't know what all that was about, whether it was wishful thinking, or more to it. You'd then end up with a situation of a breeding female, but no breeding male. Can only think that maybe an older breeding female towards the end of her fertile years might be a possibility, though I can't see another zoo allowing a female to become pregnant in the 1st place if they were then going to pass mum and baby on ?
I also took a deep breath and asked about the lack of brachiating opportunities in the new enclosure (to be fair, the keeper seemed very nice). She said that Rajang wasn't much of a climber but that they would be reviweing the facilities if and when they got younger orangs in. I persisted and pointed out (nicely) that if they were more vertical ropes he might brachiate, but that without them he diefinitely wouldn't ! ....... and she opened up a bit and said that they'd been considered, but decided against and that they (meaning the keepers I presume) didn't understand why they weren't included but that they (the keepers) didn't have much to do with it (the design).
