Huh, I had no idea windows were so deadly to birds. Via @[588732176:2048:Christine Peterson]
"Decals that stick to the glass are not very effective, but strips of tape on the outside of the glass, or strings or feathers hanging outside the window, each no more than 10 inches apart, are fairly effective. Decorative features like stained glass designs or window dividers can achieve the same result. Outside screens are very effective both to reduce the reflection and to cushion the impact. In short, anything that reduces or breaks up the window’s reflection will reduce bird strikes."
