Wood Pecker Pecks

We've got a dilemma now - a wacky woodpecker who keeps hitting our front window and taking chunks out of our new house trim!  We've already tried shouting him away and putting items in the window to try to scare him away.  Next suggestion we'll try is getting a rubber snake and putting it on the ledge to see if that gets him away!  Check out our visitor's picture!

Update - Following a variety of suggestions put forth by PG ISlanders, we dropped mothballs in the hole the wood pecker pecked, put a rubber snake on the ledge below the window and another one in the hole, strung some fishing line in front of the window to blow in the wind and finally placed a dummy owl in the window.  The wacky woodpecker is gone; I guess we were just too much for him/her.
