@FunkyGibbon Americans, of course! Apparently there is a corner exhibit with some Texans and their cattle; a New York display with humans perpetually wandering around a museum; a few cowboys and grizzlies in the Montana ecosystem; a really cool alien habitat in the New Mexico complex; a mini-General Motors factory setup in the Michigan exhibit; and some gators and fishermen in the Louisiana coastline aquarium. That last zone actually won an AZA Best Exhibit award!
@FunkyGibbon A lot I don't have the exact species list, but I would estimate about 15 species of reptiles, including Rosy boa and Alligator, several frogs, a few Callichtrids, Sloth, two species of Armadillo, Guinea pig, Agouti and a dozen of birds, like Burrowing owl, Gambell's quail and some interesting passerines. Then there is the aquarium in the basement.
@snowleopard Then the exhibit is rather poor. Where are the carnival dancers of Rio, the peruvian lama shepherds, the guarani tribes and the Caribbean beach tourists?
