I have raised cockatiels and kept parakeets. I kept cockatiels and raised them for over 25 years, my last little guy passed away about 10 years ago at the age of 23. I know how old he was, since I hatched him. I had some Peach Faced love birds, too noisy!

And to just add, cockatiels are parrots! Big bird in a compact size . . . 
If you like cockatiels you would LOVE an African Grey.
