They all can be bad, but IMHO, hawks are the worst since a good electric fence keeps the ground dwellers at bay, hawks don't seem to mind figuring how to defeat covering of the run....
btw it is NOT illegal to "harass" them (other than a couple endangered species) killing without a permit (good luck getting that) is illegal. In fact there is a hawk thread here where the legality is explained in detail of running them off without killing them; and in my experience until they learn to fear you they WILL come right in with you there!
