Aviary

Whats in here?

Peacocks

I was thinking they looked like they were built for hornbills, so I had a quick look for another photo.

Is it the same double-aviary as in this photo by Hix where they were housing Indian Hornbills? (The aviaries look much larger in your photo than in his where there is a person for scale, but they have the same "bridge" between the two aviaries).

They are at least identical, but now I'm wondering if there are two of these doubles?
In any case, hornbills would be a big upgrade.
