1.3 Grevy's Zebras recently arrived at the Zoo. They replace the Grant's Zebras that were previously displayed at the Wild Africa zone. A pair of Grant's Zebras are still on display at Night Safari, but will likely be phased out.
@Loxodonta Cobra i recall hearing that the zebras came from the US and Europe, brought together under the EAZA breeding program. There are some zoos in Japan that have Grevy's.
