@ThylacineAlive this doesn’t look like much of an enclosure to me. Not trying to be critical but it looks more like of a way for the macaws to travel on and interact with guests outside.
@John Marchwick I think it's better than the "parrot on a stick" display most zoos do. This is of course only part of it and the little house structure makes it a bit better.
I think one thing we can be really thankful of in Europe is that parrots on a stick are almost non-existent. Sadly they are still all too common in Asia.
