'World's Largest Aviary'

The Niagara Falls Aviary, also known as Niagara Falls Aviary: Birds of the Lost Kingdom, is an aviary (or bird zoo) located in the tourist district of Niagara Falls, Ontario, Canada. The building previously housed the Niagara Falls Museum. Re-opened as a free flying aviary in May 2003, it is now one of the largest indoor aviaries in the world, encompassing approximately 45,000 square feet (4,200 m2), and it houses over 300 individual birds, a majority of which come from Australia, South America, and Africa.
