Flight Behavior:

The Northern Harrier typically migrates alone. They soar, but more frequently flap and glide while migrating at tree-top level. Occassionally, they will rock in flight like a turkey vulture.

Feeding habits:

Northern Harriers search in open habitats, flying close to the ground in buoyant gliding and flapping flight. They prefer to hunt in areas with mixed vegetative cover and avoid short vegetation. Harriers feed on small to medium sized mammals, particularly rodents, as well as birds, reptiles, amphibians and insects.
