@birdsandbats I took this photo right around the time we found out they'd switched to South American, so most likely it's the original signage. I didn't see a coati so I can't say which was in there at the time.
I have not seen it (hiding the couple times I have been seen they got it), but it is South American. The sign you see in the window says it is closely related to the white-nosed coati native to the Sonoran Desert (which is why they have a photo of one).
This is not the main (and far more spectacular) coati exhibit, which has been empty for a couple years. It will likely remain empty for a while because they are going to do construction in that area for a new riparian habitat. This was a gray fox exhibit; the fox is now moved to the exhibit at the opposite end though for a very brief period they had a fox in both. Originally (decades ago) this was a jaguarundi exhibit.
