I am semi rural, on the edge of what use to be a big farm and so there is lots of bird activity. There are several hawks, a few large and a few smaller ones and when they are near, everybody else scatters ! Sometimes one sits on my back fence, facing the field and sometimes I see a large one sitting on the fence across the front road at the edge of the horse pasture. So far, I have never actually witnessed one take another bird or rodent down, but there is a bunny that lives under the bushes at my back fence and one day it "appeared" to be a mature hawk and a young hawk and I thought the older one was trying to show the young one the ropes. They were camping out in some trees beside my yard and I was just sure "bunny" was going to be their lunch, but a few weeks later, I saw bunny again and was kind of happy that it had not been a victim.
