I've actually been working on a project where I'm making pie graphs of different zoo's continent representation. So far I've finished the St. Louis Zoo, and I'm working on the San Diego Zoo. One of the things I've been noticing is how both zoos have very little European animal representation.
That seems to be quite common in North American zoos (very little European animal representation). I can't think of any zoos in the US or Canada with a dedicated Europe area... as "Eurasia" at the LA and Toronto Zoos are both mostly focused on Asia. I'd love to see a Europe exhibit at a North American zoo. I don't think Russia's Grizzly Coast at the Minnesota Zoo counts because 1) it primarily focuses on Asian Russia and 2) North American animals are used as stand-ins.
