🚨 Lights Out Alert🚨 An estimated 23 million birds are expected to pass through Wisconsin tonight during a major migration event tonight!
Most birds migrate at night, and artificial light can disorient them and draw them toward buildings, increasing their risk of window collisions. Turning off unnecessary outdoor lights from 11 p.m. to 6 a.m. can help give migrating birds a safer path through our communities.
We can make a bigger difference when we do it together. Talk to your neighbors, friends, local business owners, and community leaders about turning out unnecessary lights tonight. The more of us who take part, the more we can reduce artificial light across our communities.
