of Tropical Realm was converted to house a pair of aye-aye and a group of Malagasy giant jumping rats. The outdoor area houses a group of cotton-top tamarins. European Aviary This aviary was formerly home to Andean condors and American Black vulture but is now the home to a variety of European birds after Europe on the Edge was demolished in late 2017. The species include here consist of European black vultures, (being the zoo's largest birds of prey). There are also Eurasian spoonbills, northern bald ibises and little egrets as well as a selection of waterfowl. Smaller birds include rock doves, azure-winged magpies and the native but rare red-billed chough. Rare Parrot Breeding Centre Parrots housed off-show here include red-vented cockatoos, lesser sulphur-crested cockatoos, red-and-blue lories, Mount Apo lorikeets and blue-and-yellow macaws. The only ones on show are Ecuador amazons. Most of the birds were moved to the Rare Parrot Breeding Centre from the old parrot house when it was demolished in 2005 to make way for Realm of the Red Ape. Magnificent Macaws This exhibit consists of two aviaries housing rare and endangered South American parrots and macaws. These include great green macaws, in the aviary outside of the Tropical Realm and blue-throated macaws and elegant crested tinamous in the other, next to the Sand Lizards. Aquarium The aquarium is a small and traditional building (one of the oldest at the zoo, built by George Mottershead's daughter and son-in-law in the 1950s) housing a varied collection of freshwater and marine fish, aquatic invertebrates and amphibians. It has had notable success breeding seahorses and achieved the first captive breeding of the freshwater motoro stingray. Other notable fish include Pinstripe Dambas, Mudskippers, tropical reef fish and various Lake Malawi cichlids. Invertebrates such as starfish, sea urchins and several species of coral and shrimps are housed with the fish. Asian Plains and paddocks In 2008, Asian Plains received its official opening. Based around a mixed-species paddock featuring Burmese brow-antlered deer, the exhibit has recently been extended to include new enclosures for greater one-horned rhinoceros. The male rhino was joined by a female in 2008 to form a pair which the zoo hoped would breed. Sadly in November 2009 the male Indian rhino Patna was put down due to a longstanding leg injury. The zoo obtained a replacement male from Edinburgh Zoo in March 2010. Since they were closely related the previous
