History of the Bird House

Bird aviaries and waterfowl ponds have long been a part of the Smithsonian's National Zoo. The first aviary or "flying cage" at the Zoo was constructed in 1901 and was located nearly underneath where the new Asia Trail bridge spans today. It was a dome-shaped structure 158 feet long by 50 feet wide by 50 feet tall, and was one of two commissioned by the Smithsonian Institution. The original at the Zoo was demolished in 1975.

The second cage was sent to St. Louis for the 1904 Louisiana Purchase Exposition and World's Fair. The site of this World's Fair was incorporated into the St. Louis Zoo. The second cage was recently renovated and serves today as an exhibit for North American birds of the Mississippi River cypress swamps.

An eagle cage was incorporated into the hillside (along the western side of the proposed site) in 1932. This cage was demolished in fall 2004 as a part of the cleanup effort after the wetlands boardwalk fire. Remnants of a man-made rock cliff remain on site near the footprint of the Eagle Cage.

Construction of the Bird House began in spring 1927 and was completed and opened in the summer of 1928, with exterior work and outdoor cages completed in 1929. The final third of the building was added in the late 1930s.

Construction began on the Great Flight Cage in 1963 and it opened to the public in 1965. It received an award for excellence in design by the American Iron and Steel Institute.
