Roz is right ....... that's why I posted this picture a couple of months back because there'd been speculation a few days before. You can just about make Sasha out left of centre (right of his platform).
This is an excellent exhibit indeed, saw it back in 2003. Would love to visit Colchester Zoo again, but only when they stop playing those ridiculous 'jungle sounds' at every exhibit. Cheep CD music from the souvenir store will not make me think I'm in Kenya or India. Only a zoo visitor on acid would actually think that.
