Buteo regalis
North America's largest buteo, big enough to be mistaken for an eagle. The light morph is rusty brown above with a pale head and underparts, and the legs are feathered down to the talons. It is well regarded in falconry.
The ferruginous hawk (Buteo regalis) is a large hawk endemic to the arid grasslands, prairie and shrub steppe of interior North America; 'ferruginous' means rust-coloured. It is the largest North American buteo and is often mistaken for an eagle. Of the roughly thirty Buteo species worldwide, only the upland buzzard of Asia averages larger in length and wingspan. The wings are long and broad and the tail grey, rusty or white. Like the rough-legged buzzard, its legs are feathered to the talons. There are two colour morphs: light birds are rusty brown above and pale on the head, neck and underparts with rusty legs, while dark birds are dark brown throughout. There are no subspecies. It hunts mainly small mammals such as rabbits, hares, ground squirrels and pocket gophers. It is a well-regarded falconry bird, but its size, power and aggressive temperament make it unsuitable for beginners, and it is recommended for experienced falconers. In Japan captive-bred birds are sold by raptor specialists.
