Elegant and precise are words that always seem to come to mind when watching Northern Harriers fly the fields in search of a meal. The Northern Harrier is a very distinct looking hawk hawk with their owl-like face and easily identifiable in flight by a white patch at the base of their tails.

Northern Harriers are the most owl-like of hawks (though they’re not related to owls). They rely on hearing as well as vision to capture prey. The disk-shaped face looks and functions much like an owl’s, with stiff facial feathers helping to direct sound to the ears.

Northern Harriers hunt mostly small mammals and small birds, but they are capable of taking bigger prey like rabbits and ducks. They sometimes subdue larger animals by drowning them.
