Parrots, also known as psittacines are birds of
the roughly 372 species in 86 genera that make up
the order Psittaciformes, found in most warm and
tropical regions. The order is subdivded in three
families: the Psittacidae, the Cacatuidae (cockatoos)
and the Nestoridae (New Zealand parrots). Parrots
have a pan-tropical distribution with several species
inhabiting the temperate Southern Hemisphere as
well. The greatest diversity of parrots is found
in South America and Australasia...
