They hunt during the daytime.Like most hawks, they use two forms of hunting; still-hunting (watching for prey from a perch and then stooping) and watching for prey while in flight. Unlike most other large raptors, they may engage in hovering flight above the ground while searching for prey.

'''Nesting:'''  Sexes are alike with females being larger.  The plumage is predominantly brown in color and often shows a high degree of speckling. A broad brown chestband is present in most plumages and a square dark carpal patch contrasting with the white under-wing is an easily identifiable characteristic in light morph individuals. There are a wide variety of plumage patterns are exhibited in light vs. dark morphs, males vs. females and adults vs. juveniles and they can easily be confused with the [[Eurasian Buzzard]] (''Buteo buteo'') and the [[Red-tailed Hawk]] (''Buteo jamaicensis''). Distinguishing characteristics in all plumages include long white tail feathers with one or more dark subterminal bands. The wing tips are long enough to reach or extend past the tail when the animal is perched. The common buzzard can be similar-looking, with a similar long-tailed shape and can be notoriously variable in plumage. The rough-legged is longer-winged and more eagle-like in appearance. The red-tailed hawk is chunkier-looking and differs in its darker head, broader, shorter wings, barring on the wings and the tail, dark leading edge to the wings (rather than black wrist patch) and has no white base to the tail. The [[Ferruginous Hawk]] is larger, with a bigger, more prominent bill and has a whitish comma at the wrist and all-pale tail

Nests are built soon after arrival to breeding grounds and require 3–4 weeks to complete. Twigs, sedges and old feathers are used as building materials. They sometimes contains the bones of caribou along with sticks. Nests are 60–90 cm (24–35 in) in diameter and 25–60 cm (9.8–23.6 in) in height. Cliff ledges and rocky outcroppings are preferred nesting sites.
