The easiest way to stop birds from pecking on a window is to take a piece of ribbon, cord, ski line, whatever and drape it along the frame or base of the window being attacked.  The bird will associate this with the illusion of a snake and stay away.  Works for us every year that nutty cardinal comes back to protect his babies.
