I have "black crows" and "owl" decoys all over my back yard and they do work! I have owls that move their heads,,,,,and yes, you have to spend the time to move the decoys all around the yard.....those nasty hawks are smart, and they will notice if the decoys never move! I even have big black crows I got from a Halloween store....big birds with wings out stretched....I hung them from a string so they would "fly" when the wind blows.....looks fake to me, but I think the hawks are buying it! |
