Damn all the magpies!

If I threw large rocks at birds, would that be bad?

You all know about my paralyzing fear of birds, well my sentiments towards them go far beyond hear and well into hatred. Especially for magpies....oh magpies. They make the absolute worst sound ever ( you know the one, its the sound satan makes), and for some reason they love to make this sound early in the morning right next to my window. Now sleeping without the window open in a non-airconditioned house in july is not an option, so I need help.

Please someone, save me from the magpies.
