A light rain was falling on Friday morning, October 2, 2020, while fog shrouded the city. During a short time, an estimated 1,500 native migratory birds were killed within a three-and-a-half block radius of Center City Philadelphia. Earlier that night, the cloud cover was low, and the moon was full, at peak migration. Birds use the moon and stars to migrate and are attracted to lights within buildings but have little experience with glass. Seeking a safe place, they fly into windows, confused by the artificial light and reflective glass. Many of these deaths are preventable, but require using bird-friendly materials and enacting building standards designed to reduce the use of reflective glass.

The source imagery for these bird drawings is courtesy of Stephen Maciejewski, a former social worker and tireless Audubon volunteer, who rescues injured birds and collects and catalogues bird fatalities in Philadelphia. Stephen’s work and photographs galvanized members of the birding community to create “Bird Safe Philly” which soon established “Lights Out Philly,” a voluntary program that encourages turning off or blocking as much light as possible during peak migration times in spring and fall.
