Looking at the Date/Time info on the picture this picture was taken 2014:08:09 13:35:14,so I would suggest they are not back on-show and its just bongorob finally getting round to post the picture!
Rob said in the chatroom earlier that he did see this species today, displayed next to the bushdogs in the magpie aviary though he may have been pulling our legs!
bongorob's photo of the baby Malayan tapir has the same date
I think that even Dr Watson would solve this conundrum - particularly as Rob dated the post.
