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. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most variably sized bird order in terms of length. 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 altricial (helpless) young.
an African grey parrot has a life span of 40 to 60 years, Amazon parrots have 25 to 75 years of life span and so on. Small parrots such as hanging parrots, lovebirds and budgets have shorter lifespans of up to 15–20 years. The cockatoo of Major Mitchell is the oldest living parrot which was 82 years old. moo
The birds have learned how to trade a token for food: one each for a low, medium or high value food. The task was to choose between an instant food reward and a token that they could exchange for higher quality food. In control tasks, however, selecting a token resulted in an equal or lower payoff.
The parrots only rejected the immediate reward and chose the token, if the token's value corresponded to a higher quality food compared to that of the immediately accessible food. The results show that parrots are capable of deliberate and profit-maximizing decisions. At the same time, they provide evidence that certain motivational factors can influence decision-making, because for some individuals, the token itself had an intrinsic value that prevented them from choosing economically in control tasks
