Bird-Safe Window Treatments and Products

A range of window treatments can dramatically reduce bird-window collisions in homes and commercial buildings.

Key Facts

External window films with ultraviolet-reflective patterns are visible to birds but transparent to humans
Zen Wind Curtains, CollidEscape, and ABC BirdTape are commercially available solutions
Spacing of any deterrent pattern must be no wider than 5 cm vertically and 10 cm horizontally
Internal blinds and screens are less effective than external deterrents applied to the glass
New architectural glass standards increasingly incorporate bird-safe elements for commercial buildings

Welfare Considerations

Window collisions are the second largest human-caused source of bird mortality after habitat loss. Practical, affordable solutions now exist for both residential and commercial buildings. Wider adoption of bird-safe glass standards and retrofit treatments could save hundreds of millions of birds annually.
