Turns out I was wrong, the "future and newly renovated black rhino exhibit" will not be for a black rhino it will be for an Indian Rhino. I do not know whether or not it will be for the nearby Manjula oor if the zoo is getting a new one.
There are also a few changes as well. In Jungle Trails, in the Orangutan/Gibbon exhibit, the vines in the outdoor habitat have been raised and expanded from tree to tree for better brachiation. In Manatee Springs, the Hermit Crab exhibit was taken off display completely, the green tree frogs and brown anoles were as well, and lastly dollar Sunfish have been placed in the former, small saltwater tank.
In Dragons! The unnecessary walls that create small turns have been taken down by both the entrance and exit.
In World of the Insect, in the aviary, the Jumbo Fruit Dove and the African Pygmy Goose have been taken off. Sad that I'd never see the "goose" again, I discovered that it was moved to the aviary in Jungle Trails.
