Cockatiel is equivalent to about 18 human years old.

  • At 5 years old, Cockatiel has completed about 25.0% of the average captive lifespan for the species (20 years).
  • Young adult birds are usually at peak energy and curiosity. Annual vet check-ups and a stimulating environment help maintain that vitality.
  • Based on the average lifespan, your bird may have approximately 15.0 more years - though well-cared-for individuals often live beyond the average.

Next stepThe best investment at any age is a relationship with a certified avian vet. Even a healthy-bird baseline exam gives you a reference point for future check-ups.
