A finch has been tapping on R's window all week!

What does that mean? lol It will fly up to a tree and come back to the brick windowsill and sit/tap it's beak on the window. I assume it is the reflection. 

Any way to stop it? R does not care for the birdie knocking at his window. I was about to line the outside with empty beer cans to keep it from landing, but thought it might look trashy. hehe
