Physiology of the sparrowhawk

Sparrowhawk: what is it like

The Eurasian sparrowhawk’s body length ranges from 29 to 41 centimeters, with a wingspan of 67 centimeters; its mass varies from 171 to 314 grams. The embryo stage has a body length from 3.5 to 4.2 centimeters and a body mass from 15 to 25 grams. During the fledgling stage, the young have a body length from 10 to 25 centimeters and a body mass from 20 to 180 grams. The post-fledgling stage shows young individuals with a body length from 25 to 38 centimeters and a body mass from 120 to 220 grams. Adult individuals have a body length from 29 to 34 centimeters and a body mass from 110 to 200 grams.

The quail hawk is a small predatory hawk. It flies quickly between trees and catches small birds in the forests of Europe and Asia.
The quail hawk differs from the goshawk by its smaller size and ability to fly quickly through dense forest. It is important for nature because it limits the number of small birds and rodents.
