I have been having a lot of success with this just a thin piece of rebar held up with rebar. Foam doves on the wire and a mojo on each end. I leave the foam birds out all dove season. Some of my foam birds have been missing since horses are in that pasture I thought they were pulling them off. Last week my nephew called me and said I was missing a dove.
He said while dove hunting a hawk swooped down and snatched one of my birds off the rebar and took off with it. Guess time to buy some more birds.
