Roger Williams Park Zoo Faces of the Rainforest is another exhibit that could easily be considered amongst the worst new exhibits in the AZA. Not only does it waste space, many parts of it are considerably less natural than the exhibit it replaced and I do not believe the cost of the building justified the end result. The building may look cool on the outside, and the additions of giant otters and piping guans are exciting, but I do think the exhibit could have been significantly better executed, and have been designed in a way such that less space was wasted. Even if they wanted the building to be the current size, they could have designed in a way so that the kangaroo walkthrough didn't need to be abolished and so that maned wolves were not dropped from the plan, and returned king vultures to the area.
