@PossumRoach I visited the park for work, so I was on a private tour, but yes, currently you must book a special experience to see any of enclosures only visible from the tram tour. The tram tour is expected to reopen within the next couple of weeks, however. The only field exhibit visible otherwise is the East Africa exhibit.
@Wyman - I think it's vastly more interesting that they are managing a breeding pair of black rhinoceros in a mixed species exhibit than to be concerned about the subspecies not being geographically accurate for the exhibit. None of the field exhibits have inhabitants that 100% match what the exhibits are called-- it's just not realistic.
Awesome picture. Do you know why black rhinoceroses are never seen in mixed species exhibits? Do they seem to be meshing well with the other species in the field exhibit?
