- Small cockatoo species, such as the cockatiel, have an average lifespan of 15-20 years.
- Medium-sized cockatoo species, such as the umbrella cockatoo, have an average lifespan of 30-40 years.
- Large cockatoo species, such as the palm cockatoo, have an average lifespan of 50-60 years.
However, it's important to note that these are just average lifespans, and individual cockatoos may live shorter or longer than these ranges. Proper care, diet, and veterinary care can contribute to a longer lifespan for cockatoos.
