I was told this information from a state wildlife officer named Kevin Behr. It is legal to kill hawks in the state of Ohio.
Accorging to the Ohio Revised Code, Section 1533.07: No person shall catch, kill, injure, pursue or have in his possession either dead or alive, or purchase, expose for sale, transport or ship to a point within or without the state, or receive or deliver for transportation, any bird other than a gamebird, or have in his possession any part of the plumage, skin, or body of any bird other than a game bird, or disturb or destroy the eggs, nest, or young of birds.
The owner of domestic animals or fowl may kill hawks or owls causing damage to domestic animals or fowl while such damage is occurring. Once they brey on a flock of domestic animals, they do not quit. IF a bird of prey is killed, the carcass needs to be disposed of and no part can be possessed, including the feathers.
