Several below have had problems with Hawks. This past summer I saw SOMEPLACE wind socks that looked like all kinds of birds. One was a big Bald eagle. These socks had wings that actually flapped in the wind if suspended from a tall flexible 'fishing pole'like rod. I am just wondering if any one has tried one of these (say owl or eagle) to deter wild hawks. I personally do not have a hawk problem but just a noseyness that might help others.... Later, like this!
