Zoogeographic zones. May 8, 2018. It's worth noting that the zoo doesn't actually follow these in their exhibitry, with there being no animals representing the "Eurasia" zone and there being an additional "Central America" zone. That said, most of these zones are only used to group animals together on the species list on the map and most of them are actually displayed randomly throughout the grounds except for a general North American section and Asian section (though that one still has Kea, which is grouped in the "Australia" zone).
