Hanging Cords (BirdSavers)

Hanging cords in front of windows (also known as BirdSavers) can be a highly effective and attractive way to reduce bird-window collisions. They can be made at home using simple, affordable materials.

Effectiveness

A study of BirdSavers using olive-colored cord found them to reduce bird-window collisions by more than 90%.

Cost

The material costs to treat a 3′ x 5′ window with a simple BirdSaver design (paracord suspended vertically from a horizontal header cord) would be around $11-$17.

Installation

BirdSavers are simple to make, but can be time consuming when treating many or large windows. Installation is also simple, providing your windows are accessible from the ground or ladder.
