With the right diet Cockatiels live on average 18-20 years, and sometimes longer. A Cockatiel's diet should consist of plenty of pellets, a little seed and the occasional treat. Salad or other greens are also acceptable additions to a Cockatiel's diet. In the wild a Cockatiel enters its nest hole backwards or tail-first due to its very long tail. A Cockatiel's voice starts to develop at around 12 weeks of age and by 6 months is pretty well developed.
