 (Or order custom Acopian BirdSavers here)

‘Quick Guide’ to make your own Acopian BirdSavers

    • Use 1/8″ diameter (approximate), dark colored, paracord (nylon parachute cord). Use Polyester cord if the cords will be attached at both the top and the bottom for cords that will be longer than about 8 feet.
    • How to make your own BirdSavers:
    • Attach the paracord on the outside of the window, above the glass.
    • Space the vertical hanging paracord anywhere from 3.5” to 4.25” apart.
    • If you are concerned about wind blowing the cords, the bottoms of the  cords can be attached below the glass, although many people like the effect when the cords stop about 2” above the bottom of the glass.
    • When you are finished, please send us some photos. We would love to see your BirdSavers! Thanks.
