I have a cockatiel that is 10 years old and we expect to have her another ten years or more. She talks up a storm, fusses at the dogs and is just like another member of the family.
One of my cockatiels will be 15 years old in October. Never had a problem except for a bad molt a few years ago. He looked pretty ragged, but the vet said he was OK.
(For anyone looking for an inexpensive member of the parrot family as a pet, I highly recommend cockatiels. Sweet, funny, and affectionate. But folks have to devote time to them, since hand-raised birds are bonded to humans. They’re not meant to just look pretty in a cage, like finches.)
We had cockatiels but I was not that good with them as they were not comfortable with me, bit the heck out of me and did not like the wings clipped.
At the same time our neighbors had one and they watched 700 Club back then daily.
Their Birds fave saying “Praise the Lord”. : )

...is probably a he. The females don’t usually talk. My tiel hoots a lot, but has never talked :) The macaw’s, however, never shut up! lol
