I’m hoping the hippo IRA shouldn’t be too far away from finishing, meanwhile with NZ’s research the giraffe IRA shouldn’t take too long. Xenarthra I’m hoping will follow, with nothing else really on the horizon afaik. If the giraffe IRA doesn’t get completed, there’s always NZ as the middleman. A couple month quarantine with the individuals spread between the facilities would no doubt attract a lot of visitors with the fear of missing out. What if instead of the insect house being there, it’s in the Aussie section where all the kids will be, if not next to the butterfly house. This means the exhibit could be expanded to potentially hold bonobo, with mandrill hopefully next to duiker(species idk). That strip of the Congo would include the African Dwarf Crocodile, Okapi, Bongo, Yellow-Backed/Blue/Zebra Duiker and mandrill. The gorilla rainforest would have Ring Tailed Lemur, Black and White Ruffed Lemur, Red Ruffed Lemur, Western Lowland Gorilla, Pygmy Hippo, Bonobo, Black and White Colobus (exhibit also home to Pygmy hippo).
Just a note that the quarantine period required for the giraffes in a third party would be 12 months, but Hamilton Zoo have the space to accomodate them and could facilitate this potentially. It’s worth considering if Australia want to prioritise other species for an IRA.
That all sounds good, but I’m of the opinion Melbourne Zoo will likely j hold either Black and white ruffed lemur or Red ruffed lemur (not both). They’d ideally need two exhibits if they wanted to breed either as females have to be transferred out if males are in the exhibit as they fight with their mother. Socially, they’re very different from the gregarious Ring-tailed.
