The white hawk is the largest bird of all species of hawk, the male is up to 60 cm in length, weighs up to 1350 g and its wingspan measures up to 130 cm. The female, as is normal in birds of prey, is larger than the male, with a length of up to 65 cm, a weight of up to 2,100 g and a wingspan of up to 160 cm.
A notable feature is that these birds are adapted for both hunting in the air and on the ground, unlike the peregrine that only hunts prey in flight. That is why their claws are more blunt and powerful than those of their southern relative, since hunting on the ground requires this type of specialization. Like all the members of the family, it finishes to its prey by means of a point of its hooked peak in the neck.
