Do any other zoos have mixed species displays with spur thighs and antelope? I always thought it would be a cool idea. There aren't a lot of mammal-reptile mixes around that I'm aware of. Maybe in Europe? I recall hearing that Brookfield once kept a species of crocodile in the Ibex Island exhibit with baboons and ibex. Probably quite a while back!
Most mammal-reptile mixed displays often include tortoise, turtles, or iguanas....I have seen some with crocodililans too (mixed with primates, fruit bats, or muntjac).
Hogle Zoo has aldabra tortoises with a kangaroo, a wallaby, and a pair of coscoroba swans. Zoo Boise used to keep red-footed tortoises with their cotton-top tamarins.
