I have a couple questions first is there such thing as the AZA Animal Exchange I read a book and it talked about it, it said this monthly TV magazine size booklet had a list of animals, gender, facility name, and price. Does this still exist today? I know they have loans and animals are traded but do they have this. If so how much would a Gorilla, Elephant, or even a Sea Lion cost for a zoo. Another question with the AZA code of ethics how can zoos get away with giving animals to unaccredited facilities. For instances the Metro Richmond zoo has a Mishmi Takin from the San Diego Zoo, the Tennessee Safari Park has Red River Hogs, Bearded Pigs, Natal Red Duikers, and other ungulates from the San Diego Zoo. The Animal Kingdom zoo has Mandrills and other primate species from the Buffalo Zoo. These animals are relatively new so how do zoos get away with this or is it simply no where else for these animals to go. I don't mean to throw these great facilites under the bus, but I am interested in this topic please post a response.
