I too read somewhere last year about placing cd's on the clothes line. We have a chicken wire fence for the dogs off the back porch, and I went and got some flashy pinwheels and zip tied them to every post. It looks rather funny, but I haven't seen any birds of prey hovering around any longer. Myah also has a light weight dress, that has a strip of flashy sequins on it that I put on her when she goes outside.
Before we put all the flashy stuff out....we had birds circling over head all the time. Not any more.
