I went to Banham Zoo in August and met Akiko (before his move to Edinburgh) and Khal. Kulki had an enclosure behind the two public ones so he wasn’t viewable, and one of the keepers said that Yinto had been moved to another zoo, but I couldn’t find out where.
Khal spent most of the day high up in the tree in his enclosure, out of view. He seemed very happy to relax up there!
