I had a Lutino tiel that I got from my boyfriend's grandfather. I knew she was old, but I had no idea what her age was. I had her for about 6 years, then she got sick and I had to put her down. I thought she was about 18 when she died. My boyfriend's grandfather came to visit the next week and he told me she was at least 23. So they could have a lot of years left.

PS. They are beautiful!
