Eurasian sparrowhawks have a typical lifespan of from 15 years and 2 months to 25 years and 3 months, with a maximum recorded lifespan of 20 years and 3 months, and a theoretical lifespan ranging from 14 years and 4 months to 20 years and 6 months. The age of sexual maturity for the species ranges from 3 months and 1 week to 3 years. During the "Embryo" stage, the developing embryo grows within an egg, utilizing nutrients from the yolk and not feeding independently. The "Nestling" stage lasts from 3 weeks and 3 days to 1 month, during which the young are covered in down and completely dependent on their parents. Following this, the “Rapid Growth Juvenile” stage lasts from 6 months to 2 years as the young bird learns to fly and hunt independently. The "Adult" stage, when the species is able to reproduce and successfully hunt, lasts from 1 to 10 years.
