This related thread What zoo has the best display/# species of North American animals? got me thinking about how many zoos there are in the United States that have ONLY animals native to the United States. I realize a lot of zoos have a section devoted to their region as well as animals from other parts of the world. Those are included in the other thread. I am simply interested in a list of facilities (zoos and aquariums and nature centers) that have American animals exclusively. If they have a section for that but also sections for other parts of the world, please do NOT list them. I am using the term American and America to refer to the United States specifically (which is how the term is generally used), though of course I am well aware that America consists of two continents covering dozens of nations.
