A stock dove aged 5 years is like a human aged 21 years 3 months

If a stock dove is 5 years old, that is like a human aged about 21 years 3 months (accuracy ±6 months 2 weeks). It is not “multiply by 7”: the calculator matches life-cycle control points — birth, puberty, adulthood, average and maximum lifespan — and builds a conversion curve from them.

How old is a stock dove aged 5 years in human years?

About 21 years 3 months (accuracy ±6 months 2 weeks).

Why is the age not converted linearly?

Animals age differently: for some, childhood lasts a month, for others a decade; some live to 5, others to 200. So the calculator does not multiply by 7 — it matches up to 8 life-cycle control points.

Can I choose another age or animal?

Yes, the calculator is right on this page: pick the animals, sex and age or birth date, even an approximate one, and the result updates.
