vine-clad, glass-roofed pergolas link the three major exhibit areas—tropic, temperate and polar—housed in discrete buildings of brick trimmed with granite, masked by vines. The exhibit areas are centered around a square central garden that contains a square sea lion pool in its center. The sea lion pool is surrounded by glass fencing to allow visitors to observe the sea lions and their daily feedings. Exhibits and other buildings The structure at the central garden's southwestern corner is the "Tropic Zone", which contains a two-story representation of a rain forest. The rain forest contains Rodrigues flying foxes, Seba's short-tailed bats, emerald tree boas, pythons, cotton-top tamarins, white-eared titis, toucans, black-and-white ruffed lemurs from the Bronx Zoo and a large variety of birds including scarlet ibis, emerald starlings, superb starlings, pied avocets, speckled mousebirds, sunbittern, troupials, Taveta golden weaver, blue-crowned motmots, crested couas, blue-gray tanagers, African pygmy goose, ochre-marked parakeets, white-fronted amazons, blue-headed macaws, plum-headed parakeets, Derbyan parakeets, Fischer's lovebirds, golden conures, red bird-of-paradise, superb bird-of-paradise, Nicobar pigeons, black-naped fruit doves, Victoria crowned-pigeons, coroneted fruit doves, kagus, blue-and-yellow- and green winged macaws. The zoo also keeps piranhas, pig-nosed turtles and red-footed tortoises. There is also a large free-flight area for birds. The elephant house of the original menagerie was formerly located at the site. To the west of the garden is the "Temperate Territory", a landscaped series of paths surrounding a lake. It hosts animals such as red pandas, white-naped cranes, snow monkeys, and snow leopards. A snow leopard exhibit in the Temperate Territory opened in June 2009. The Temperate Territory is located on the site of the 1934 zoo's cafeteria. The northern side of the garden is adjacent to the "Penguins and Sea Birds" section. This multilevel structure contains a chilled penguin house that contains macaroni penguins, king penguins, chinstrap penguins, gentoo penguins, tufted puffins and an outdoor pool with harbor seals, as well as an outdoor grizzly bear exhibit. It is located on the site of a lion house that was built in 1934 along with the original menagerie. The eastern side of the central garden is next to the Arsenal, technically located outside the zoo. The structure was completed in 1851 and originally intended as a weapons and ammunition storehouse for the New York State Militia. It once served as an actual zoo building, but now contains NYC Parks Department offices. Central Park Zoo also includes a 4D theater,
