Recently we have been woken in the early hours of the morning by very loud noises like someone throwing stones at the windows. After a couple of nights of this, we managed to catch sight of the culprit, a huge magpie banging on the window with his beak. We think he was attracted by bright shiny photo frame on the windowsill. Obviously I have moved this now, but the banging is still happening every couple of nights. There are still some items (books etc.) on sill but nothing shiny. Anyone heard of this happening before? More importantly, any suggestions to stop it?
