You don't. Unless you A: apply for the permit in order to shoot them. B: illegally harm them. Remember, they are federally protected and fines are HUGE. Also, nature abhors a vacuum, so killing one will just suck another into the opened up territory.
If they are safe and just fussing, big deal. Mine fuss whenever a swallow or crow flies by. They are just reacting to a potential aerial threat.
I find it funny that people have so many issues with birds of prey. Just the other afternoon I was on the porch watching my chickens free range in the tall grass. A coopers hawk was flying over the fields looking for a meal, dipping and weaving. It passed right over my birds and eventually found itself a nice rodent. Considering the chickens would have been easy prey, it must be hard for most chicken owners to realize that NOT every bird of prey is out to eat your chickens.
