Aquarium du Quebec - Pavillon des profondeurs, Hyacinth Macaw

Is that a glass case for macaws, with wire on top? Or is the front of the case also wire? It's a bizarre enclosure!

@snowleopard The front is also wire, just this one side is glass; it's the only side people directly face. Not sure if it was a design choice or done specifically because of a behavior of this bird. It's the only enclosure here that felt off, or too small, which makes me think there must be a reason for it, hopefully?
