Save migrating birds from window collisions

10% off Feather Friendly DIY deterrent markers, ABC BirdTape & Bird Divert

Feather Friendly features adhesive markers applied to the outside of windows. When the backing is removed, a grid of dots or small squares is left behind. The markers can be removed if needed and do not cause any permanent damage to the glass. The DIY product lasts 8+ years if installed correctly; Pro DIY product lasts 10+ years.

The company also manufactures and sells ABC BirdTape, a white or light blue vinyl material applied to windows in long strips or a pattern of squares. The tape lasts an average of four years, and is translucent enough to allow natural light through and not impact the view. It’s easy to apply and customize.

As well, the company offers Bird Divert, which uses ultraviolet (UV) reflective technology that takes vantage of most birds’ ability to see in the UV spectrum. The markers are designed to reflect UV wavelengths up to 420 nanometers, creating a pattern birds recognize as a barrier, while remaining practically undetectable to the human eye.
