Parts of Europe and Asia have several kinds of harriers, but North America has only one. Harriers are very distinctive hawks, long-winged and long-tailed, usually seen quartering low over the ground in open country. At close range, the face of our Northern Harrier looks rather like that of an owl; like an owl (and unlike most other hawks) it may rely on its keen hearing to help it locate prey as it courses low over the fields.
Has disappeared from many former nesting areas, especially in southern parts of range, and surveys suggest that it is still declining in parts of North America.
|Marshes, fields, prairies. Found in many kinds of open terrain, both wet and dry habitats, where there is good ground cover. Often found in marshes, especially in nesting season, but sometimes will nest in dry open fields.|
Mostly small mammals and birds. Diet varies with location and season. Often specializes on voles, rats, or other rodents; also takes other mammals, up to size of small rabbits. May eat many birds, from songbirds up to size of flickers, doves, small ducks. Also eats large insects (especially grasshoppers), snakes, lizards, toads, frogs. May feed on carrion, especially in winter.
