I love seeing these Cuvier's Gazelles! There are very few here in the U.S. (and I believe that they are descendants of animals imported from European Zoos) and this is one of the few captive antelope species that I've not had a chance to see (and I haven't see ANY antelope species in the wild besides our native Pronghorns).
@Summer Tanager This is my first time seeing them too; they're quite shy animals, their paddock has rather reduced viewing windows, so thsy don't get too stressed by people.
