No, I didn't visited Safari Park. The most important species, such as California Condors and superb bird of paradise, are also at the Zoo, so, since I knew that they had already no saiga nor black-footed ferret, I planned to don't visit it much before take flight. Just giant eland would be not enough for change my plans, but if they have had many other rare ungulates absent from the zoo, I would tought in it...
I mean, they do have a lot of rare ungulates not at the zoo. The aforementioned elands and Red-Fronted Gazelles, as well as Patterson's Elands, Ugandan Kob, Barbary Red Deer, Grant's Gazelles, Cavendish's Dik-Dik, Sitatunga (the US ssp is different from the ones kept in Europe), Fringe-Eared Oryx, Cape Buffalo, Bontebok, Eastern White-Bearded Wildebeest, Cape Steenbok, Slender-Horned Gazelle, Desert Bighorn Sheep, and Springbok..
Oh yes, I see, thanks. But if you don't count subspecies (that I don't care about), there is not much more that interest me. The steenbok and the giant eland are the only "must" for me, the springbok too but as it's more commonly kept, for sure I will end finding it in another zoo.
@Kakapo even outside of the Groves splits Cavendish's Dik-Dik and, I think, Fringe-Eared Oryx are now thought to be separate species from the ones you have in Europe. And surely Ugandan Kob, Grant's Gazelle and Slender-Horned Gazelle would be of interest to you?
@Giant Eland That row of hoofstock paddocks near Northern Frontier. This particular paddock was once you exit NF and begin to head down the hill towards the birds of prey exhibit. On the map on the website there's a zebra by it.
