@Jake my recollection was a little fuzzy to provide a full list, based off a quick google search it holds: white rhinos, Thomson's gazelle, addra gazelle, greater kudu, fringe-eared oryx, eastern bongo, common waterbuck, and sitatunga.
@m30t Also some ostrich in here. The fring-eared oryx, kudu, sitatunga, bongo and finally White Rhino are breeding groups. The other species do not breed, or at least the zoo has not publicized it. Even with large groups of most of the species, except the addra gazelle it still feels pretty empty in here. But its 40 acres so what do you expect.
