Hawk behavior

[Nicky Davis <nicky-davis at earthlink dot net>]

I'm trying to decide if the hawks (I think I have 2 different ones) coming into my yard are SS or Cooper's. The one that came today wagged its tail each time it landed. It went from a tree to my wall around the yard to the top of a bird feeder to the ground, back to the wall and then flew off.  Each time it landed it wagged it's tail. Is this a characteristic behavior for both the SS and the Cooper's? It's an adult.
