I have been to Cleveland and enjoyed it a lot. Both the excellent Rainforest building plus some other excellent exhibits (Along with the Rainforest, I especially liked the African Elephant Crossing and the Primates, Cats, and Aquatics Building). To be honest, Cleveland was not one of the zoos I was thinking about when writing about sunbittern, ringed teal, and scarlet ibis. Cleveland, while it does have those species, at least does a decent job of including some other unique species in the walkthrough aviary as well, such as Red-Crested Turaco (a personal favorite of mine), Chestnut-Naped Green Imperial Pigeon (which I don't think are that common in zoos), Luzon Bleeding Heart Dove (a surprisingly active and visible individual, might I add), and Crested Oropendola. Plus it's just overall a great, lush aviary that's a nice home for both the free-flying birds, the turtles, and the large mammals. Pair that with a good orangutan exhibit (soon to become an even better orangutan exhibit), some solid habitats for some small carnivores, and a great herp/invertebrate collection, and the RainForest at Cleveland is one of the most solid exhibits I've seen anywhere (since I started keeping track, I've been to 22 zoos and the RainForest ranks as my number 1 exhibit, and Cleveland as my number 1 zoo).
