One of several walk-through aviaries at the zoo, all of which were locked. One was closed because the Milky Storks inside were breeding, but another (the Amazon aviary) was completely empty of birds, and this one was almost empty. I'm not sure what's going on there.
I took this photo from the side of the aviary, through the mesh, which makes the interior look terrible but it wasn't as bad as it appears.
The signage said the aviary held Lesser Mouse Deer, Small-clawed Otter, Island Fruit Bat, Lesser Short-nosed Fruit Bat, Green Heron and Black-naped Oriole. The only species I could see (from outside the aviary, but I could see the whole area) were the Short-nosed Fruit Bats, what looked like a Greater Mouse Deer, a Green Heron, a Cattle Egret, and a couple of Asian Brown Tortoises.
