Psittaciformes are generally believed to be long‐lived birds and are frequently said to reach ages of 100 years old or more. In reality, however, life spans rarely exceed 50 years of age, although a few reliable records exist of parrots aged up to 65–70 years. Cockatoos appear to have the highest longevities and the longest reproductive life spans. Larger psit‐tacines are generally longer‐lived than smaller ones, although there seem to be some exceptions to this trend and quite remarkable differences in longevity between some similar‐sized parrot genera. Some particularly interesting longevity histories, information on maximum breeding ages and trends in longevity are discussed.
