@lintworm It's the indoor western lowland gorilla habitat, but the gorillas haven't used it in quite some time. These days it's shared by a pair of Abdim's storks and a hadada ibis.
@lintworm Yes, it seems the whole gorilla family shares the outdoor area. The storks are always perched around that spot in the picture, but the ibis is way up near the top of the atrium on those pipes, so they must be able to fly.
