It is a large prey of birds that have distinctive identical markings in both sexes. The term “ferruginous” refers to the reddish-brown or rust color.

The ferruginous hawks have a reddish upper back, white breasts, pointed tips, brownish rust back, and wings. These species form two types of coloration i.e. light morph birds and dark morph birds.

Ferruginous Hawk

Moreover, it has a white head with a dark streak that extends behind the eyes. At the time of the flight, the ferruginous hawks form a “V” shape and its underparts are light colored with dark legs.

Previously, it was called ferrugineous rough-leg which was closely related to the rough-legged hawk. Similar to rough-legged, the ferruginous hawks have rusty or whitetails, long broad wings, and legs feathered to the talons.

Mainly, it can be observed in savanna, forest edges, river edges, thorn-scrub woodlands, and clearings.

Feeding: Its main diet is small mammals, lizards, snakes, large insects, frogs, and some birds. Usually, they sit in an open high-perch area to swoop their prey.

4. Swainson’s Hawk (Buteo swainsoni)
