There are 4 gorilla enclosures, which is similar to what is done very well at Zoo Atlanta. In Omaha the human walkways are mazelike, and they are grey cement bunkers. The gorilla yards are all naturalistic but not huge in size, although it is interesting to see them share space with colobus and diana monkeys indoors. Also, there are "bubbles" where humans can look and see gorillas only inches away.
I'm not sure if the gorillas are rotated, and the entire area is quite confusing to navigate. The bland, featureless human area is deliberately boring and nothing but grey cement, and the idea is to shock visitors as they peer out at lush ape enclosures. I'm not a huge fan of this area of the zoo, as I think that the nearby 65-foot tall pair of orangutan exhibits are much better than the gorilla habitats. With the gorillas the human "bubbles" are cool viewing areas, as is an overhead glass tunnel. There is a red river hog/cattle egret exhibit somewhere in the maze, and Wolf's guenons are somewhere in there as well. Apparently visitors are always within about 20 or so feet from a gorilla, and it is definitely a unique way to exhibit the apes.
This photo is just one of the gorilla yards, and I think it is the smallest as well. The hallways through the building have multiple views of multiple exhibits of active bachelors which is quite thrilling, not a family group in sight until the end of the exhibit sequence. I like the contrast of an architectural human space (the corridors) with the fairly naturalistic gorilla exhibits.
