Parrots, also known as psittacines ( /ˈsɪtəsaɪnz/), are birds of the roughly 372 species in 86 genera that make up the order Psittaciformes, found in most tropical and subtropical regions. The order is subdivided into three families: the Psittacidae ('true' parrots), the Cacatuidae (cockatoos) and the Strigopidae (New Zealand parrots). Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere as well. The greatest diversity of parrots is found in South America and Australasia.

The Singapore Zoo (Chinese: 新加坡动物园; pinyin: Xīnjiāpō Dòngwùyuán; Malay: 'Taman Haiwan Singapura'; Tamil: சிங்கப்பூர் விலங்குக் காட்சிச்சாலை), formerly known as the Singapore Zoological Gardens and commonly known locally as the Mandai Zoo, occupies 28 hectares (0.28 km²) of land on the margins of Upper Seletar Reservoir within Singapore's heavily forested central catchment area. The zoo was built at a cost of S$9m granted by the government of Singapore and opened on 27 June 1973. It is operated by Wildlife Reserves Singapore, who also manage the neighbouring Night Safari and the Jurong BirdPark. There are about 315 species of animal in the zoo, of which some 16% are considered threatened species. The zoo attracts about 1.6 million visitors each year.

From the beginning, Singapore Zoo followed the modern trend of displaying animals in naturalistic, 'open' exhibits with hidden barriers, moats, and glass between the animals and visitors. It houses the largest captive colony of orangutans in the world.^{[citation needed]} In 1977, primatologist Dr Francine Neago lived inside a cage with eighteen orangutans for six months to study their behavior and communication.
