There is a similar enclosure to the left of this photo, and the two exhibits have a pair of linking tubes that go over the heads of visitors. In theory the bats can fly back and forth between the two areas, but I'm curious as to how often the tubes are used.
I was unclear in my description on this one. The sign above the exhibit is removed, and I could just barely see what looked like a prehensile-tailed porcupine inside. I did not see any bats flying back and forth, so perhaps these two exhibits are not a success. There were certainly bats on the exhibit on the other side though.
