Couple things I can note:
The building at the end of the video is a new staff building/commissary. It should be open soon, supply chain issues have delayed some equipment arriving but the building is basically done.
The cafe is the building in 13:10, everything built to the right of it is sloth bear/otter.
The large tanks are part of LSS system, the bigger one is for the tomistoma pool.
The back of the construction behind the sloth bear/otter holding buildings is a path that will lead to the petting zoo from just to the left of the main Asia entrance. The construction yard across from peccary is going to be a large empty lot for quite a while, at least into phase 2 or 3 of the new master plan.
There will be a permanent fence placed where the chain link fence is blocking the old babirusa exhibit, and that’ll be a dead end area. The old exhibit will serve as an off exhibit breeding yard.
Construction is almost done, with a completion date of October-November. The exception is tapir/babirusa, which is the only area they haven’t touched. Muntjac have been dropped from the exhibit. The whole complex will still open the public in February. Construction is going well, even this video already outdated.
