Darn birds

A couple of birds decided to build a nest above the entry of our front door. This morning when I left for work and opened the front door, the birds attacked me. They came down and flapped their wings at me and nearly pecked at my head. Nearly every morning, I hear a loud *BOOM*, when the birds fly into the window above the door, and then into the wall. Last year, the birds also built a nest in the same place and chased my poor little dog down the street while pecking at his cute little head. This morning he tried to protect me and barked at the birds while I screamed. I've got to do something about these birds or else I'm not going to be able to use the front door for awhile.
