Parrots found in most tropical andsubtropical 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 inhabitingtemperate 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 feet. Many parrots are vividly coloured, and some are multi-coloured.
The most important components of most parrots'
diets are seeds, nuts, fruit, buds and other plant material. A few species sometimes eat animals and carrion, while the lories and lorikeets are specialised for feeding on floral nectar and soft fruits. Almost all parrots nest in tree hollows (or nest boxes in captivity), and lay white eggs from which hatch young.
