SDAS member Shiela Preston shared this information regarding bird window collisions.
Message: I discovered something amazing this summer. I have a sunroom with all windows and we love to feed the birds. Unfortunately we were getting two or more bird hits a week and sometimes daily. I searched for a solution on line and I bought the large bird stickers but they really didn’t do much at all.
I was reading about birds and one article said that they done like white or shy away from it. So about three months ago I ordered a plastic white flag banner and hung it outside across the top of the window. Since then we have hardly had any hits. And no dead birds. I got the flags in white from Amazon.
