Conservation status Threatened. Has declined seriously over most of its range; current population may be fewer than 4,000 pairs. Causes of decline include shooting, loss of habitat.
Family Hawks and Eagles
Habitat Plains, prairies. Found at all seasons in very open and dry country. Inhabits dry grassland, sagebrush plains, saltbush and greasewood flats, rangeland, desert. In winter, also in agricultural country, including over plowed fields.
This regal bird is the largest of our soaring Buteo hawks, a fitting raptor for the wide skies and windswept plains of the west. It soars with its broad wings held in a shallow V, and swoops down to catch ground squirrels, snakes, young jackrabbits, and other good-sized prey. It is often seen sitting on the ground in open fields. Except when nesting, the Ferruginous Hawk seems curiously unafraid of humans, often allowing close approach.

Feeding Behavior

Hunts by watching for prey while soaring high, flying low, or from a raised perch. Sometimes waits on ground near active burrow of pocket gopher, then catches the rodent as it comes to surface.


2-4, sometimes up to 6 or more. Pale bluish-white fading to white, usually marked with brown. Incubation is by both sexes but female does more, and male brings food to her. Incubation period 32-33 days. Young: Female remains with young at first; male brings food, female feeds it to young. After about 3 weeks, both parents hunt. Age of young at first flight about 40-50 days.


Female remains with young at first; male brings food, female feeds it to young. After about 3 weeks, both parents hunt. Age of young at first flight about 40-50 days.


Mostly small to medium-sized mammals. Feeds on most readily available small prey, such as young jackrabbits, ground squirrels, pocket gophers, kangaroo rats; also cottontails, mice, others. Also eats birds, snakes, large insects.


Pairs may circle high above nesting territory, calling. Nest site is usually in top of tree, 20-50' above ground, but can be as low as 6' (available trees may be very short). Sometimes nests on cliff or on ground. Nest is bulky structure of sticks and debris, lined with finer materials, including cow dung. Historically, some nests were built of bison bones and lined with bison dung. Nest may be reused and added to annually until it becomes huge.
