@MennoPebesma I read that on Facebook, but I did not mention it. Not sure why they took them out of the South American monkey forest, they seemed to fit in quite well there. I do hope a second monkey species will be kept again in there. That said, I also read they intend to start keeping black howler monkeys with pied tamarins in the former Carboniferous area (near the bush dogs).
@MennoPebesma That's a legimate reason, sure. I do think the building for the monkey forest is probably a bit on the small side and perhaps should be enlarged, even if just for the squirrel monkeys.
