I don't know, I've found this picture in my collection, it is a Trading card from the series"The World famous San Diego Zoo-Animals of the wild", published in 1993. I have the complete collection, full of brilliant pictures of rare species ! But I think, the zoo kept rhinos always in the elephant mesa.
was this were the giraffes are currently in elephant mesa or were the bairds tapirs and capybaras used to be ?
North side of the mesa, where tapirs and capys were. It was a very basic enclosure for these amazing animals.
The exhibit now holds a rotating cast of wolves, cheetahs, New Guinea singing dogs, and domestic mutts!
Actually it is quite an in-genius way of training somewhat difficult animals for being educational animals/animal ambassadors. They've been doing it for quite some time, just that they display them in this netted enclosure instead of not at all.
Simple math: Sumatran Rhino > ANY domestic dog or cheetah companion regardless of the ingeniousness of their training.
