Just wanted to share that last week, I placed a shiny spinning pinwheel on the same post where that hawk is pictured (in my post (#47)) and next to it some mirror garland (several 2" square mirrors connected with fishing wire) hanging over the fence. Since then I have not seen or heard hawks in my yard, nor have the chickens been freaking out about a predator. The mirror garland constantly throws random reflections, so I hope it's doing the trick and not just a coincidence that the hawk is gone!
