This is a very nice-looking Black Rhinoceros enclosure. I'm glad to see that they have a more grassier enclosure as oppose to the ones found over here. That said, with the Black Rhinoceros being a browser, it would be more benefited naturally with the addition of some shrubs or maybe a tree or something. Though that's, of course, not something the zoo would add if they were specifically trying to control what and when the rhinos ate.
