Cooper's Hawk

We had another hawk in the neighbourhood on Monday. I was just about to take supper off the BBQ when I spotted it on the neighbours light post.  Duncan & Drew are going to have to wait a few minutes for there supper while I get my camera and head up the street to get a few shots. It seemed unaware of my presence for a few minutes and then it suddenly flew off. I wonder if it was looking for some supper to enjoy? Maybe they have discovered our growing squirrel population and are going to help reduce it for us.
