There is also water buffalo, ostrich, zebra and in the pics I can just see a white antelope that is either Scimitar-Horned Oryx or Addax (probably the former).
All it needs now is rhinos and elephants, but I think that would be veeeeeeeery expensive, strengthening the fence and building new nighthomes for them. But it would certainly look good.
water buffalo Hix? forest buffalo but i didnt think water buffalo....unless thats a recent development.
sitatunga yes. oryx yes. i have never actually seen zebra in here.
at one point there were also river hippo
Wasn't aware WPZ had Dwarf Buffalo. Looking at the panoramic pic I can't see the horns, but based on the colour I'd agree Dwarf over Water.
As for the zebra, if you look at the panoramic shot there is a six-legged zebra under the shelter just to the left of center. It got it's extra legs as result of the photo-stitching process.
