Bird Kingdom is located in the tourist district of Niagara Falls, Ontario, Canada. Previously the home of the Niagara Falls Museum, the building was 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, the majority of which come from Australia, South America, and Africa. It also houses mammals, insects, and reptiles, and even an amphibian-the dyeing poison frog. Bird Kingdom has been voted Niagara Falls Attraction of the Year four times, and Trip Advisor Destination Winner for 2011 & 2012.
