Hi Jean. A friend of mine had exactly the same problem as you do with Corvids pecking at his window. I suspect they may have been seeing their own reflections and possibly attacking them. I know this can be quite common with Robins. What he did was to place something inside the window to help break up the reflections (in his case he used a piece of football netting from one of his children's nets). I don't know if this would be practical for you although his neighbours had the same problem and used various things to the same effect. After a time the birds stopped their attacks. Hope this helps you Jean.

Thanks Paul,
Yes, we thought the same about them pecking at their reflections. We live in a single storey cottage and have very wide windowsills so they peck at whichever window they can. The only exception is the conservatory which has the normal sills, so instead they peck at the door! They've been driving me mad this morning as I work from home in the conservatory and they keep landing on the roof and pecking at the panel for a solar light I have which is on the roof! You're right it would not be practical to put something up to the windows every day and would be unsightly - to be honest we have thought about getting window shutters.

Hi Jean
The reflection is the key, get yourself a roll of clingfilm and cover the outside of the glass of the windows where the attacks are focused. The clingfilm should cloud the reflection giving the birds no reason to continue their attacks. Let us know how you get on.
