Wild Bird Window Strike Prevention

Bird-window collisions kill an estimated 600 million birds annually in the United States alone. Simple, proven solutions can dramatically reduce this mortality.

Key Facts

Approximately 600 million birds die from window strikes in the US each year
Glass reflects sky and vegetation making it invisible to birds
UV-reflective patterns visible to birds but not humans are highly effective
Low-e glass used in energy-efficient buildings is particularly dangerous to birds
Most strikes occur at residential homes rather than skyscrapers

Welfare Considerations

Birds that survive window strikes often suffer severe injuries including brain trauma, internal bleeding, and broken bones. Even apparently stunned birds that recover may have impaired navigation and reduced survival rates. The scale of mortality makes window strikes one of the largest human-caused threats to wild bird populations. Unlike many wildlife threats, this one is uniquely solvable through product choices and retrofits.

What You Can Do

Apply bird-safe window films or decals to glass in your home
Install external screens or mosquito netting on problematic windows
Support bird-safe building legislation for new construction
Donate to organizations that rehabilitate window-strike survivors
