Many songbirds migrate at night. Light pollution from urban areas can throw them off course and increase the likelihood that they hit buildings. Adopting responsible lighting control practices and reducing unnecessary lighting at night, especially during the critical periods of spring and fall migration, are simple ways to help migrating birds. As a bonus, these techniques also lead to energy and cost savings from decreased electricity usage and help reduce your building’s carbon footprint.
