Zoo, also called zoological garden or zoological park, place where wild animals and, in some instances, domesticated animals are exhibited in captivity.. Most long-established zoos exhibit general collections of animals, but some formed more recently specialize in particular groups�e.g., primates, big cats, tropical birds, or waterfowl. Marine invertebrates, fishes, and marine mammals often are kept in separate establishments known as aquariums.
Parrots, also known as psittacines (pron.: /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 superfamilies: the Psittacoidea ('true' parrots), the Cacatuoidea (cockatoos) and the Strigopoidea (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.
Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. The plumage of cockatoos ranges from mostly white to mostly black, with a mobile crest of feathers on the tops of their heads. Most parrots exhibit little or no sexual dimorphism. They form the most variably sized bird order in terms of length.
