Wait I didn't know Oakland had half of these species. What other species did Oakland have in the past? I've heard that the zoo had dolphins at one point but I'm not so sure how true that is.
Raccoon dog, Eastern rosella, princess parrot, American kestrel, Prevost's squirrel, laughing kookaburra, spider monkey, greater kudu, lappet-faced vulture, various American ducks, bobcat, and ocelot are some of the animals that spring to mind.
The raccoon dog was where the wreathed hornbills are now. The Australian parrots and kookaburra were in some tiny aviaries near where the baboons and warthog are now. The squirrels and geladas and spider monkeys were where the squirrel monkeys are now. The bobcat and North American birds were in the old Children's Zoo. The kudu and vulture were in the African Veldt exhibit. Ocelot was where coatis are now.
Furthermore, tule elk shared the hillside with bison. Roan lived where the camels now live.
The African aviaries are now over twenty years old, and their collection has changed a lot. On my last visit, I do not recall buff-crested bustard, Lady Ross turacos, Hottentot teals, and other species that have lived there over the years. Where the elderly green monkey in Africa now lives originally housed rock hyrax.
