Possible cure for birds hitting windows

We just started staying in this place that has big beautiful windows, and lots of bird life.  Unfortunately, there were a variety of bird bodies lying on the deck under the windows with two more casualties before the week was out.In a hurry to try anything at all to end the carnage, I taped a few streamers of wrapping ribbon to the top of the windows.So far, no more bird death!This might be all it takes.  It's not terribly esthetic.  The wind blows them all around and the curly nature of the ribbon can make them knot and tangle, but as long as it works -.  I think the moving, waving ribbon, even when it's blowing clear off the glass, creates enough sense of dimension to get the point across.  This is not sky access!
