on a wing

and a prayer.
I had taken my pic I was going to use today or so I thought.
On my way home tonight, I was walking through the lane between our estate and the little trading estate and I spotted this on the path.
Whatever had taken the bird had struck it with such force, the wing had been snapped off at the bone, you can just see the speck of blood on the edge. I know we have buzzards and sparrowkawks over in the woods but don`t know what bird this belonged to..
