Hawks are known for their unique mating season and means of reproduction. Some species of hawk are monogamous and have one partner their whole lives. The male and female of a mating pair build their nest before mating season then improve it throughout nesting season. They usually do this before mating. [20] Hawks have a striking mating ritual.
The red-tailed hawk, ferruginous hawk, and rarely, the red-shouldered hawk are all examples of species from this genus that are used in falconry today.

Buteo is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in the New World (Etymology: Buteo is the Latin name of the common buzzard [1]).
Ferruginous hawks have been known to live for 20 years in the wild, [44] but most birds probably die within the first five years. The oldest banded birds were recovered at age 20. First-year mortality has been estimated at 66% and the adult mortality at 25%.
Harris's hawks range in length from 46 to 59 cm (18 to 23 in) and generally have a wingspan of about 103 to 120 cm (41 to 47 in). [6] [7] These hawks have a brownish plumage, reddish shoulders, and tail feathers with a white base and white tip. [8] They exhibit sexual dimorphism with the females being larger by about 35%.

The Accipitriformes are known from the Middle Eocene [citation needed] and typically have a sharply hooked beak with a soft cere housing the nostrils. Their wings are long and fairly broad, suitable for soaring flight, with the outer four to six primary feathers emarginated.
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 ...
The rough-legged buzzard (Europe) or rough-legged hawk (North America) (Buteo lagopus) is a medium-large bird of prey. It is found in arctic and subarctic regions of North America, Europe, and Asia during the breeding season, and migrates south for the winter. [ 3 ]
