Hmm I highly doubt. Nothing seems permanent in Bioparque do Rio. We thought the orangutan exhibit was definitive, it wasn't at all. We thought the "kings of the jungle" enclosures would be definitive, they weren't at all (we went from an exhibit with spectacled bear, who were moved for a quite bad one, now we have otters in their place. Otters that came from another enclosure at the zoo... The tiger exhibit was already occupied by brown bear and jaguar, and the lion exhibit has already held jaguar at some point). Lear's macaw? Not even six months on exhibition. King vultures took their place. Pelicans that substituted the otters? Changed to another enclosure. Flamingos who were beautifully kept in the big lake of the Burle Marx gardens? Sent to the former pelican enclosure. And these changes are just a few, not to mention the numerous moves on the small carnivore area.
Bioparque do Rio is without a doubt a very big improvement compared to the former Rio zoo, when talking about structure, at least, even if not perfect in many aspects, but they do have a lot to evolve. Zoos don't usually do constant changes like this. It seems to me that their exhibits are still lacking foliage and more specific structures for the species they hold so they can remain neutral to receive whatever species they decide to put on display. From bears to otters, from tigers, to brown bears, passing through jaguars... I understand they still have a lot of animals being held in the backstage, waiting for new on show homes, but I definitely don't think these frequent rotations are the solution. It definitely doesn't help on the animals' adaptation. Actually, pretty much the opposite.
Having said that, I honestly don't think any of these animals on the newly renovated area will be permanently kept there. Maybe the maned wolves and the pelicans, but I'm not sure. Let's keep following their steps, and hoping they get some improvements.
