In the Wisconsin area? What are some of the species you are thinking of? Any bats, moles, shrews, voles or other small rodents?
Little Brown and Big Brown are around at pretty much every nature center or wildlife sanctuary. They might have an Eastern Red Bat at Ledgeview Nature Center but I'm not sure. Franklin's Ground Squirrel is the only species still present in the area, at Shalom Wildlife Zoo, but other species pop up frequently. As for mice, similar situation to the ground squirrels. Only White-footed is present right now, at Bay Beach Wildlife Sanctuary. Other species pop up from time to time.
Audubon has Talapoin monkey, Brazilian ocelot, Nancy Ma's night monkey, St Vincent agouti. Hattiesburg, MS zoo has Blue duiker. Don't know about Jackson. Indian muntjac at Baton Rouge and other ungulates also at that zoo
Maybe so, but actually seeing the flying squirrel is rare in my experience! Usually a ball of fur at best.
Amazing Animals in Florida claims to keep Azara's night monkey Amazing Animals Inc- Meet our animal ambassadors
I've found another facility with pale fox! Cub Creek Science Camp in Missouri has 2. Pale Fox - Cub Creek Science and Animal Camp They also have a geoffroy's cat that lives with the foxes. I've found at least 4 places so far that have geoffroy's.
I highly doubt there are any actual African Leopards left in US zoos, but rather generic Leopards being called African. ~Thylo
