The Ferruginous Hawk’s range is widespread throughout most of the southern western and central U.S. The northern portion of the range only applies to breeding season, while the southern portion applies for the winter. These birds can be found year-round in very particular portions of Arizona, New Mexico, Colorado, Utah, and Nevada.

Identification

The Ferruginous Hawk is a large, stunning bird of prey, with gorgeous white, hazelnut, and dark brown feathers. Males and females appear the same, with the females usually larger than the males, while juveniles lack coloration and appear mostly white and pale brown. Adult Ferruginous Hawks have stunning dark and warm brown feathers on their wings and back, with the undersides of the wings mostly being white feathers with dark brown tips. The tan is a similar warm hazelnut color, as is the streaked head. They have a golden beak with a dark black tip, and similar colored legs. Due to the shape of their head, it appears that they have a dark streak across their eyes, but it is actually just a shadow from the bone above their eyes. These birds are commonly silent, but can give a piercing screech when alarmed.

Habitat

Ferruginous Hawks thrive in open, arid landscapes, particularly grasslands and shrub-steppe habitats, including pastures, hayland, and croplands.They avoid dense forests and prefer areas with short vegetation, often nesting on solitary trees, utility structures, or near the ground on hillsides or river cutbanks. The Ferruginous Hawk inhabits semiarid to arid western plains and intermountain regions. It occupies open country with scattered trees, primarily prairies, plains, and badlands.

Threats to Conservation

Ferruginous Hawks face several threats to conservation, primarily stemming from habitat loss and human disturbance. These threats include the conversion of grasslands to agricultural land and urban development, which reduces their available habitat and prey base. Additionally, human activities like energy development, mining, and even recreational activities can disturb nesting sites and negatively impact breeding success.
