How this parrot age calculator works
MSD Veterinary Manual publishes very different average ranges by bird group, from up to 20 years for parrotlets to 30 to 60 for macaws. The selector changes the denominator used for lifespan progress.
A human-age number is omitted because no credible, broadly accepted conversion would improve the result.

What does “percentage of lifespan completed” mean?
The calculator divides exact elapsed age by the midpoint of the cited typical lifespan range. For a parrot with a 30 to 50 year range, that midpoint is 40 years. It is a simple way to place age in context, not a forecast for an individual animal.
A result can exceed 100% when a pet lives beyond the midpoint. That does not imply anything is wrong. Typical ranges describe populations and individual lives can sit outside them.
Why exact age matters more than novelty “pet years”
Exact calendar age is stable and checkable. Human-age analogies can help make rapid early development easier to picture, but only when a credible species-specific model exists. Life Dates always leads with the real date and labels every comparison as approximate.
