The Captive Life Span
The average life span for a parrot in captivity is considerably shorter than his potential life span. This is due mostly to nutritional problems and a lack of veterinary care early in a disease process. Birds will do their best to hide their illness, sometimes until they're too ill to recover. The following lists are approximate life spans for various species of birds (keep in mind that how long your bird lives has a lot to do with proper diet and proper veterinary care):
Macaws
Macaws have been known to live well over 50 years in captivity. With proper diet and veterinary care, they should live 30 to 50 years easily. The smaller "mini" macaw's life span is at the lower end of this range.
Cockatoos
Cockatoos have been known to live well over 40 years in captivity. With proper diet and veterinary care, they should live 30 to 40 years easily.
Amazons
Amazons can live 50 years or more with excellent nutrition and veterinary care. Average life span is probably more around 20 years. Amazons are very prone to obesity and fatty liver disease, which can lead to death.
African Greys
African greys have been known to live 50 years or more in captivity. With proper diet and veterinary care, they should live at least 25 years. They are highly intelligent and prone to feather picking and self-mutilation, due to boredom or stress, which can reduce longevity.
Conures
These noisy little mischief-makers can live anywhere from 15 to 20 years, sometimes up to 35 to 40 years.
Pionus
Pionus can live up to 30 years with proper care. Their average life span is probably around 15 years.
Lories and Lorikeets
These birds usually live 15 to 20 years. Females have a lower average life span than males, due to reproductive problems such as chronic egg laying.
Parrotlets
Parrotlets have a life span of approximately 15 years. You may see them having birthdays up to 20 years.
Parakeets
Parakeets can live up to 18 years with proper diet and veterinary care. Depending on the type of parakeet, the life span may range between 15 to 18 years.
Lovebirds
Lovebirds live an average of 10 years. Occasionally, you'll run across a lovebird that's 15 to 20 years old. They can be prone to obesity and associated problems.
Canaries
Canaries may live 20 to 25 years with an average life span of 10 to 15 years.
Finches
Finches can live 15 to 20 years; however, the average is probably closer to 5 to 10 years.
Pigeons
Pigeons usually live 10 to 15 years.
Ducks/Swans
Depending on the species, ducks and swans can live anywhere between 10 to 30 years.
