Hi, thanks Moebelle for the responses. I have been to the Cincinnati Zoo before, though I don't think the Aye-Aye was there when I was. Could you go a bit more into that "festival of Lights" comment, as I might be in the area that time of the year if that works better. Is it just glass in front of his enclosure or are there bars or wire? Thank you for the comments, I'm also interested in a few of the other animals like the Sumatran Rhino, the sifakas, aardwolf, fossa etc. If there are animals you specifically find to be in great exhibits or rare, let me know

twice we've tried seeing the rhinos but they are never there when we've checked though those were often times during the winter.
Sorry for the late reply.
The exhibit is full behind glass and it is a pretty large exhibit, especially for the other two small species. The viewing is okay but if you look at my map of the Africa building you can see that there is barely any room to take a pic of the exhibit square on.
As for the rare species and their locations; here is a list.
Aardwolf-Night Hunters
Chinese alligator-Reptile House
Coquerel's sifaka-Jungle Trails
Florida manatee-Manatee Springs
Fossa-Night Hunters
Garnett's galago-Night Hunters/Jungle Trails
Grey's crowned guenon-Gorilla World
Mexican wolf-Wolf Woods
Mueller's gibbon-Jungle Trails
Pallas' cat-Night Hunters
Potto-Night Hunters/Jungle Trails
Przewalski's horse-Wildlife Canyon
Sichuan takin-Wildlife Canyon
Snow leopard-Cat Canyon
Sumatran rhinos-Wildlife Canyon
Yucatan neotropical rattlesnake-Reptile House
White lion/Southeast African lion-Siegfried and Roy's White Lions of Timbavati
As for great exhibits.
Bonobo-Greatest one in the world. Super lush/Very large/Great climbing opportunities/Indoor habitat viewing
Red panda-Two lush, overly-natural looking habitats with loud flowing water from the lake. Real plants from China and real trees for tall climbing. Best in the world.
Sumatran rhino-Large canopies to protect them from the sun. Many watering and mud holes. Just completely covered in mud to keep the rhinos cool.
