The National Aviary, located in Pittsburgh, Pennsylvania, is the only independent indoor nonprofit aviary in the United States. It is also the country's largest aviary, and the only one accorded honorary "National" status by the United States Congress. The aviary is home to more than 500 birds representing more than 150 species, and is a member of the Association of Zoos and Aquariums (AZA). Location and features The National Aviary is located at 700 Arch Street on Pittsburgh's Northside, within Allegheny Commons West Park in the Allegheny Center neighborhood. The National Aviary is open daily except Thanksgiving Day, Christmas Eve, and Christmas. Although some of the birds must be fed in private, almost all feedings (both vegetarian and carnivorous) are scheduled to be viewable by visitors. Since 1999, annual attendance has consistently topped 100,000. The National Aviary has daily interactive experiences for visitors which change seasonally. Some of these include Penguin Feedings at Penguin Point, a habitat that is home to a colony of African Penguins which offers opportunities for underwater viewing; a Penguin Encounter and a Private Penguin Feeding (for additional fees), as well as additional feedings in immersive habitats. These programs are joined by various expert talks, flight demonstrations, and encounters that help to create an immersive experience for visitors. In the fall of 2010, the National Aviary completed an $18.5 million expansion and renovation project that included the opening of a new café, classrooms, and the Helen M. Schmidt FliteZone Theater. The Helen M. Schmidt Theater is the first indoor theater in the nation built specifically for bird shows. The Aviary also began outdoor shows (weather permitting) from its new Sky Deck, featuring live flight demonstrations of eagles, falcons and kites out over West Park. Birds The Aviary is home to more than 500 birds of more than 150 species, many of which are threatened or endangered in the wild. It has one of the most diverse collections in North America. As a result, the Aviary has many species that are rarely found in other zoos or aviaries, for example, Andean Condors and the critically endangered Vietnam Pheasant and Bali Myna. Among the most popular residents are Benito and Sapphira, Hyacinth Macaws, as well as Wookiee the Two-toed Sloth both can be found in the Tropical Rainforest habitat. The Aviary has also had success in breeding; its spectacled owls had their first chick, named Franklin (after Benjamin
