We have two black and white coloured birds (I'm not a bird person and have no idea what they are, but they aren't magpies) that have recently taken up the habit of continuously flying into our windows at the rear of our home. They do it at dawn and dusk every day. They don't hit with full speed, they pull up just in time but are scratching up the glass with their beaks and feet.. It's driving me insane and short of putting up a sheet in every window have no idea how to stop them before they trash our glass windows.
Any tricks on convincing these silly birds that it's just a reflection and not a friend??? Would hanging bits of alfoil in the windows help??
