There are 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 in South America and Australasia. Parrots are intelligent birds with vibrant plumage, which is usually predominantly green with varying amounts of other bright colours. Other characteristic features include a strong, curved bill, an upright stance, short legs and strong claws. Parrots find walking a little awkward and they sway clumsily from side to side as they go! Although no good for walking; their feet, toes and claws act more like hands, enabling them to grasp food items and making them fantastic climbers.
