At every zoo I've been to that exhibited sugar gliders (or any type of nocturnal gliding mammal, actually), they are always almost impossible to locate. I've always found this interesting, since a) zoos tend to prefer species that visitors can actually see and enjoy, and b) many people enthusiastically keep them as pets, at least in the United States. I'm wondering if anyone has seen an active group of gliders in a zoo, or an enclosure that highlighted them in a memorable way?
