Hawk vs Crow

On our walk this morning, I was watching a crow at the top of a small tree, and when it flew and then suddenly swerved over to the fence I realized it had seen a hawk and was chasing it. They both landed on the fence. The extra shows the crow looking at the hawk, but you can't see the hawks face in that one. Looks to me like probably a Cooper's hawk, and definitely a juvenile (yellow eye). A Cooper's hawk is said to be "crow sized" and you can see that it is that.
