Yea, this is a bizarre exhibit. Looking at all the people in there and the size of the room, I imagine there is quite a bit of echoing and probably constant noise. The birds don't have anywhere to hide either by the looks of it. Probably terrible for the birds who will be stressed out constantly.
The building in the back is their holding space which was open for them to access. The netted space goes all the way in the back above the blue awning as well. This picture was taken as the dolphin show was let out so it was crowded, but the birds seemed unaffected by it all. At the bottom is a small pool, gravel substrate, and a few plants.
