The parrot is believed to be one of the most intelligent of all the bird species, mainly in the sense that parrots are able to replicate (mimic) the noises made around them. Some parrots are able to mimic modern sounds and human voices to almost perfection. One African grey parrot was found to have a vocabulary of more than 800 words!
Nearly all of the different parrot species around the world are known to live for a long time, particularly in comparison to other species of bird (even other species of animal). The average lifespan of the parrot is around 60 years although it is not uncommon for parrots to be much older ages, as many parrot individuals have reached the age of 100. Source: a-z animals
