The residents of the Bronx Zoo, much as their enviroment is pristine and by human standards lovely they live an artificial live. They live in captivity.

None of the migratory species are able to migrate because they exist in enclosed and controlled environments for the sole purpose o human recreation.

Oh don't take me wrong... the zoo keepers do a very good job of maintaining the environment, its flora, and habitat. After all it is a billion dollar industry.

Humans are moved on trolleys from one exhibit to another experiencing the captive wildlife through bars, glass, and moats.
