The Issue
Since 1970, there are 3 billion fewer birds worldwide. The second leading human-related cause of this loss is a result of reflective and transparent glass collisions. North America alone loses an estimated 1 billion birds are lost due to this serious conservation issue every year. This is because birds do not perceive glass and often mistake it for surrounding habitat reflected on the exterior window surface or attempt to fly through glass barriers to reach habitat that can be seen on the other side.
