Cords, strings and ribbons

Hanging cords, strings, and ribbons can be effective in preventing collisions.

Hanging cords, strings or ribbons in front of your windows can be effective and unobtrusive, even pleasant. Make them yourself or order a product like Acopian BirdSaversTM which are custom-made based on the size of your window(s).

Another ingenious invention along these lines is called The Bird Crash Preventer!TM and uses a series of monofilament line to create an effective, yet invisible warning system to keep birds from hitting windows.
