Babirusa enclosures I'm aware of are.
Islands.
Old warty pig enclosure
Old anoa Island
Old serval enclosure
Normally mixed exhibit with otters outside of rotra however the otters in the orang exhibit when I last visited
They have the ones by RORA, then in the old Serval exhibit, they also have another off-show exhibit the other side of this exhibit, it's split exhibit with an old retired from breeding female, and next to her is the main breeding male, who is moved to other exhibits to breed when needed.
There is then the ones which are reached to from this area by the keepers, but is under the walkway which goes up to where the Cheetah were, but the Wild Dogs are now.
I class that as 4 exhibits, although it's technically 5, although 2 are in the same block, it's just one house, with 2 paddocks.
The others are on Islands. The main ones you can see, which is a mum and her three offspring, and then there are the two young ones who are not on show but held in an offshow exhibit behind islands.
The groups are as follows
Mum and 2022 Offspring (Rora)
Mum and 2021 Offspring (Serval)
Retired female - offshow
Breeding male - offshow
Young male and separate exhibit with another female with access to the Walkway by Wild Dogs
Mum and three offspring - Islands
1 previous offspring - off show islands
So 6 full exhibits, but 7 if you include a split one in the same place.
13 in total, but when I was with that team in January, they did say they were planning to move on a few that couldn't be bred there. So that number may have dropped and some of the named above ones may in fact no longer be there, i,e the young male or the 1 previous young offspring.
Hope that helps.
