About Ferruginous Hawks

Ferruginous Hawks are found in deserts and open range because of their preferred hunting style from a lone tree, cliffs, or high up in the sky. It is the largest hawk to grace the North American sky. Ferruginous hawks eat small mammals sometimes standing over their entry holes and wait for the prey to pop out.

Ferruginous Hawk Behavior

They are found alone or in pairs and in the winter, they hunt in close range of each other. They roost on cliffs and pairs may be together year-round with a few exceptions where three adults have been observed in the same nest. During courtship, the pair soars into the sky performing “sky dances” where they do stead dives and ascend. They may grab onto each other’s beaks and talons as they spiral towards the ground. During the breeding season, they are aggressive attacking intruders with open talons.

What Ferruginous Hawk Eat

Their prey mainly consists of small to medium-sized mammals such as rats, mice, various
species of squirrels, hares, etc. but they are also known to feed on reptiles and other birds from
time to time. These include snakes, grasshoppers, crickets, owls, larks, ducks, pheasants, etc.
They fly over open lands in search of prey and are also known to hide and wait outside the
prey’s habitat. They follow a bimodal pattern of hunting, where they hunt in early mornings and
late afternoons.

Their diet is limited to small mammals like rabbits, hares, and ground squirrels. The western ferruginous hawks divide their diets and occasionally include reptiles, amphibians, and birds.

Where Ferruginous Hawks Live

Ferruginous Hawks are sensitive to human presence and therefore prefer the open countryside,
grasslands, and plateaus devoid of trees. They often abandon nests and territories if
encroached upon by humans. During the nesting season, nests are built in open areas or trees.
Their winter habitat is similar to that of the summer, avoiding areas populated by humans and
preferring open grasslands or plateaus.

Ferruginous hawks are grassland and open country birds with their breeding habitats in cliffs and tree groves. They spend the winter in deserts abundant in hares and rabbits.

Range and Migration

Ferruginous Hawks are native to North America. They usually reside in the interior parts of
North America, with habitats ranging from South-Western Canada, Western United States and
Northern Mexico. Their year-long habitats are concentrated in and around the states of Utah,
Colorado, New Mexico, and Arizona in the United States, with nesting around the Northern parts.
They are known to winter in Western, South-Western, and Southern parts of North America
along with some parts of northern Mexico. They migrate short to medium distances. Ferruginous
Hawks in the Alberta to Texas regions tend to first move in the South-East direction and then to
the South, following the grasslands. Certain populations that nest in the South are known to be

Ferruginous Hawk Lifecycle

Ferruginous male and female hawks chose a nesting site together and build the nest together with the male searching for most of the material and the female doing the construction. Nest materials include twigs, sticks and metal debris. The female lays an average of 8 eggs and on a minimum of 1 per breeding season. She incubates the eggs for 32 to 3 days. It takes at least 38 days for the chicks to be strong enough to fly out of the nest.

Ferruginous Hawk Nesting

During the breeding period cultivated fields and modified grasslands are avoided as locations
for nests, open areas, trees, and swamp oaks near waterbodies are preferred for the same,
though the presence of water near the nest is non-critical. They maintain minimum distances
from other nesting raptors, and nests facing different hunting territories are tolerated better as
compared to nests facing the same hunting territories. Courtship and copulation occur during

and after the nest-building period and carry on until the laying of eggs. Nesting period typically
lasts between 38-50 days.
