Yaş
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.
Fenotip
The Eurasian sparrowhawk chick possesses a small beak already featuring a hook, and receives torn prey from its parents, while a quantity of soft down feathers helps retain body heat. Young birds after rapid growth have brown plumage on top and dark stripes underneath for camouflage, and they possess sharp claws on their feet to grasp and hold prey, as well as a number of wings that allow for quick maneuvering between trees. Adult Eurasian sparrowhawks have a short, strong beak with a sharp hook to tear prey, and a quantity of large yellow eyes with keen eyesight to spot prey from a distance. The female’s plumage is brown on top and white underneath with dark-brown stripes, whereas the male’s plumage is greyish-blue on top and white underneath with reddish stripes that aid in courtship displays. Adult birds have long, sharp claws that firmly hold caught birds, and a number of short, broad wings allow for sudden turns in forests during chases.
