An aviary is a large enclosure for confining birds, although bats may also be considered for display. Unlike birdcages, aviaries allow birds a larger living space where they can fly; hence, aviaries are also sometimes known as flight cages in the United Kingdom. Aviaries often contain plants and shrubbery to simulate a natural environment.
