Large, reflective windows often trick and injure or even kill birds. Birds are fooled by reflections of nature in windows or a window may be so clear that birds cannot even see it and believe that they can fly right into your house. If you believe that you have a hazardous window, try one or more of the following to minimize the risk. Cover windows with netting or hang ribbons or other strips of material on the outside. Close your blinds or draw the drapes during the spring and fall migration seasons. Hang hawk silhouettes of aluminum or wood to deter other birds (moving images are most effective). Angle windows down during installation to decrease the likelihood of a mirror like reflection of the outside world. Place bird feeders less than one yard or more than three yards away from the window. Cover window with spray starch to reduce reflections.
