[10] A molecular genetic study published in 2019 unexpectedly found that the Eurasian goshawk and the American goshawk were not sister species.
Hunting in groups of two or three, the hawks soar at a height of 50 to 200 m (160 to 660 ft) in the sky. When one of the birds spots prey or a rotting carcass, they signal to the other members. The dominant hawk of the group feeds from the prey until it is satisfied, as the other hawks in the family group submissively wait their turn to feed.
Hawks, including the accipitrines, are believed to have vision several times sharper than humans, in part because of the great number of photoreceptor cells in their retinas (up to 1,000,000 per square mm, against 200,000 for humans), a very high number of nerves connecting the receptors to the brain, and an indented fovea, which magnifies the ...
