on teaching visitors the importance of plants and improving energy efficiency. The Calgary Zoo achieved LEED (Leadership in Energy and Environmental Design) Gold in energy conservation and responsible building practices, the first facility of its kind to achieve this level of certification. Exploration Asia (Formerly Eurasia) The western portion of St. George's Island is dedicated to Eurasian animals. Animals in this area include Amur tigers, snow leopards, Pallas's cats, Japanese macaques, red pandas, Japanese serows, Bactrian camels, and Komodo dragons. This section was also home to four giant pandas which debuted in early May 2018. The giant pandas were on loan from the Chengdu Research Base in Chengdu, Sichaun, China. Panda Passage featured adult male Da Mao, cubs Jia Yueyue and Jia Panpan as well as their mother Er Shun. Since then, the pandas have been returned to China because of bamboo supply chain issues arising from CoVID-19. Formerly residing in the Panda's habitat area was a herd of Asian elephants (relocated to the Smithsonian National Zoo) and later a male Indian rhinoceros named Sabari (now residing in Safari Niagara, Ontario). The area known as Panda Passage has since been renamed to Gateway to Asia and has seen the addition of a Malayan tapir and 2 white-handed gibbons. Prehistoric Park The Calgary Zoo's six-acre Prehistoric Park features life-sized dinosaurs in their re-created geographical environment, including replicas of an inland sea and volcanic mountain, and more than 100 species of living plants. Dinosaurs include Albertosaurus, Allosaurus, Ankylosaurus, Apatosaurus, Baryonyx, Centrosaurus, Corythosaurus, Deinonychus, Dilophosaurus, Edmontosaurus, Elasmosaurus, Euoplocephalus, Iguanodon, Metriacanthosaurus, Nothosaurus, Omeisaurus, Pachyrhinosaurus, Parasaurolophus, Protoceratops, Pteranodon, Pterosaur, Stegosaurus, Struthiomimus, Styracosaurus, Tanystropheus, Triceratops, Tylosaurus, Tyrannosaurus rex, and Yangchuanosaurus. Penguin Plunge Penguin Plunge and a renovated gift shop were opened in the spring of 2012 and is located at the entrance of the Calgary Zoo. The exhibit includes king penguins, Humboldt penguins, gentoo penguins, and rockhopper penguins . Penguin Plunge consists of two main areas, an indoor climate-controlled habitat and an outdoor open-air habitat. In summer, the outdoor exhibit holds the warm-weather South American Humboldt penguins which are housed inside during the winter. On winter days when the temperature is between +5 °C and -25 °C without wind above 20 km/h, the king penguins go on scheduled walks for exercise and enrichment. Other/Former Animals The zoo contains a flock of Chilean flamingos next to the enclosure containing both a herd of alpacas and greater rheas.
