I decided to look into what zoos are accredited by the AZA, and they don't seem to have any privately-owned zoos. I was surprised to know that even zoos like Perth and Taronga aren't accredited by them, but rather the ZAA, but I do know Perth and Taronga aren't privately owned as far as I can tell. (No, I don't live in Australia, nor have I been, but I just have seen pics and heard about these zoos and they seem great). What shocked me the most was that Australia Zoo isn't accredited by the AZA. Other zoos that seem good but aren't a part of the AZA include Wildlife World Zoo, Bearizona, and probably more, but I didn't research all of them. I know there's another Australian one, National Zoo and Aquarium, that also isn't accredited by the AZA. Unless there's some zoos I missed, it doesn't seem that the AZA likes privately-owned zoos. What's the reason for this?
