Ground Perching – the hawk will stand on the ground at a rodent burrow after initially locating it from the air. As the burrowing animal reaches the surface, the hawk rises into the air and pounces upon it even while it is still underneath the loose earth.
Low-level Flight – birds will course over the landscape within a few yards of the ground and pursue in direct, low level chases, or they will hunt from 40 to 60 feet (12 to 18 m) above the ground.
High-level Flight – birds will hunt while soaring, but the success rate is generally low.
Hovering – using quickened wing beats, often in times of increased winds, the birds will search the ground and drop on the prey.
Cooperative Hunting – mates have been known to assist each other.
Piracy – the Ferruginous Hawk has been observed gathering around a hunter shooting prairie dogs, and to claim shot "dogs" by flying to them and mantling over them.
cultivation of native prairie grassland and subsequent habitat loss
tree invasion of northern grassland habitats
reductions in food supply due to agricultural pest management programs
shooting and human interference
Toxic chemicals have not been suggested as a significant threat to the Ferruginous Hawk. Management strategies must include the retention or reclamation of native grasslands for breeding as well as on the wintering grounds. Maintenance of high populations of prey species in wintering areas seems critical to the hawks' abilities to move onto the summer range in breeding condition. The integration of agricultural practices and policies into the management strategies is a crucial component of any overall scheme for conservation. The provision of nesting platforms has had positive effects and should be a part of local strategies. Public education and the elimination of persecution and human disturbance must be an important part of the overall conservation program. Source
