Why go Lights Out?
Most birds migrate at night, employing an incredible sensory system to navigate and to orient in darkness. Light pollution attracts and disorients these migrating birds, disrupting these systems and increasing birds' vulnerability to collisions with structures. An estimated 365 – 988 million birds die in collisions with buildings annually, including a number of species of high conservation concern. You can help dramatically reduce the hazards from light pollution for nocturnally migrating birds by turning off all non-essential lighting.
