They had two, brother and sister Sav and Serena.
Welcome to ZooChat! I always like seeing more New Englanders around here. Indeed, I understand there are good reasons for a lot of the weak spots I mentioned, and looking at each one in a vacuum they are understandable. That said, when looked at holistically, it is clear that Capron is in a bit of an awkward transition period right now, with infrastructure that needs to be replaced, a number of species being phased out, and economic struggles that makes getting the necessary work done difficult. It isn't necessarily going to be easy, but if the zoo could find ways to fix some of these, it could substantially enhance the visitor experience. Even simple changes can go a long way. If new animals isn't possible in the old nocturnal building right now, perhaps the zoo could look into placing some graphics over the empty exhibits to give visitors something to look at. For Rainforest, housing a larger flock of an existing species could be an alternative to bringing in an entirely new species. If a new sloth bear isn't possible, hopefully the zoo moves as quickly as possible to find a new species suitable for that exhibit, whatever it may be.
Take this as you will; I just called the zoo and the person who answered told me he is not that knew, but arrived about six months ago after plans to get a pudú dissolved.
Will the pair up the remaining individual with an unrelated partner?
I believe the building in question is the nocturnal building that the zoo recently announced is closed until further notice for a renovation into a "new exhibit experience."
The Capron Building is indeed the Nocturnal Building, and is the oldest building in the zoo (at one point being the entire zoo). I have no clue what the current plan for that building is, but I will say renovations of it are sorely needed, and the collection in that building has been declining for the better part of a decade now. Whatever happens to that building, at minimum there is a need for behind-the-scenes improvements (e.g., heating and HVAC systems), and hopefully some of the currently empty exhibits will be filled too.
I wonder if this means something is going to be done with the lemur islands, as I'm assuming the black-and-white ruffed lemurs will move somewhere too. Then again, I might be making a lot out of nothing. If something is being planned, I hope it entails removing or changing the water body and the islands because they're all a waste of space, but that will cost a lot of money that I expect isn't available.
