Parrots, also known as psittacines are birds of the roughly 372 species in 86 genera that make up the order Psittaciformes,[4] 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).[5] Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere as well. The greatest diversity of parrots is in South America and Australasia.
