Nature at Work

I was wondering how I could get a good photo of one of the birds on my feeder, when the question was answered for me.  I heard a loud bang and went to the window to see if a tree had fallen in the yard.  I looked down on the patio and discovered the source of the sound.  A hawk had captured a Mourning Dove, after flying into my kitchen window.  I believe it's a Cooper's Hawk.  After spending a few minutes on the patio, it flew into the tall trees, with the dove in its talons.
