Up to one billion birds die from window strikes in the US annually. Simple modifications to buildings significantly reduce this preventable welfare toll.
Window strikes cause traumatic deaths or serious injuries to hundreds of millions of birds each year, making glass buildings one of the largest human-caused sources of bird mortality globally. A bird hitting glass at speed typically suffers blunt trauma including brain injury, internal bleeding, and broken bones. Survivors often succumb to delayed neurological injury or become easy prey. This is a welfare crisis with widely available solutions - deterrent films, external screens, and bird-friendly glass can dramatically reduce the toll.
