Hawk Ferruginous basic information
There are generally two color variations (or morphs) for the ferruginous hawk, the 'light morph' and the 'dark morph'. The darker of the two is a dark brown to cinnamon in color. The exceptions to the solid color being a white patch on the top of the wing and a yellow stripe by the beak. The lighter of the two variations generally gives the bird rust colored backs and shoulders. The head would be paler with gray tints and streaks. The wings often get large white crescent shaped patches on the upper side with a dark comma shaped patch underneath. The leg feathers start white as a juvenile, darkening to a rust color as they get older. The bird's underside is white with either spots or streaks. This pattern generally gives the bird a white tail tipped with a pale rust color. The name Ferruginous literally means rust colored. Arguably the largest bueto in North America, the ferruginous hawk has an average length between 22 and 25 inches, with a wingspan range generally between 53 and 56 inches. The females are often slightly larger than the males up to an average of three point six pounds (1,231 g) versus the three point one pound (1,059 g) average for males.
