Physical Description

Ferruginous Hawks are usually between 50-66cm (20-26 in.) in length, have an average wingspan of 134-152cm (53-60 in.) and weigh 980-2030g (2.2-4.5 lb.). They are the largest hawks in North America, and are sexually dimorphic. The female hawk may be up to one-and-a half times larger than the male. "Ferruginous" is derived from the Latin Ferrugo, meaning, "rust", which is the predominant color of this hawk. Adults have a rusty color on their back and shoulders, which extends downward onto the legs. The under-part is a whitish color spotted with rufous. A view of the bird in flight will show that the leg feathers form a V shape against the belly of the hawk. When perched, the gray tips of the hawk's long and broad wings often reach the tip of their white, rust, and gray colored tail. Juvenile Ferruginous Hawks lack the rust colored legs and have less color on their backs (Malik 1987; Clark 1987).

Range mass: 980 to 2030 g.
