The zoos in the US that have pangolins are the Brookfield Zoo, Columbus Zoo & Aquarium, Memphis Zoo, and Essex County Turtle Back Zoo.
At one point, Pittsburgh and Gladys Porter were also holders - unsure exactly which facilities still hold them currently.
Does anyone know the exact number of Tree Pangolins in the US. It seems like it's a decent amount.
As I already said, the population statistics are not known to the public - overall or at any individual facility. No way to keep track when nearly all of them are behind the scenes and the zoos are not providing regular updates on their status.
Yes, thats an interesting debate for sure.
For reference, this was that debate - or at least the primary one, the discussion has come up multiple times since. Also the original source of information about the import and project: https://www.zoochat.com/community/threads/several-us-zoos-receive-pangolins.466979/
