First opened in 1982, the zoo's historic Aquatic Bird House featured two main theater-style galleries. The first featured three species of penguin - the rockhopper, chinstrap and king penguins, all in an 18,000-gallon, temperature-controlled pool, with a chilly temperature of around forty degrees Fahrenheit for the air and water, while a computer system imitates the natural daylight cycle penguins experience in the wild. The second gallery featured puffins, murres and razorbills swimming in a 10,000-gallon pool based on the North Atlantic coast, where the birds made their homes on rocky cliffs. The historic building closed on December 5, 2011, and is being replaced with Regenstein Macaque Forest. The sixty-six birds that lived in the previous exhibit were moved to eleven other locations, including the Shedd Aquarium, the St. Louis Zoo, the Detroit Zoo, the Central Park Zoo and the Oregon Coast Aquarium A new African penguin habitat was built by the current site of the Robert McCormick Bear Habitat, and opened in 2016.
