The theme of this year’s World Migratory Bird Day, “Dim the Lights for Birds at Night,” focuses on the impacts of light pollution on migratory birds. Most birds migrate at night and need dark skies to safely navigate between their breeding and non-breeding grounds. Light pollution attracts and disorients migrating birds, making them more likely to land in areas where they are more vulnerable to collisions and other dangers. There are many things we can all do to reduce artificial light at night. Learn more and see tips at migratorybirdday.org/takeaction.
