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.https://www.allaboutbirds.org/guide/Northern_Harrier/overview
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.https://www.allaboutbirds.org/guide/Northern_Harrier/overview
