DEVILS LAKE - With fall migration underway, Audubon Dakota encourages community members to help birds safely journey to their wintering habitat by participating in Lights Out for Birds. Every year, millions of birds migrate across North and South Dakota. From Sandhill Cranes, ducks, and geese, to songbirds, like the Black-and-white warbler, most migratory birds make their remarkable bi-annual migration at night. Since they use natural cues by which to navigate in the night sky, light pollution from buildings and brightly lit homes can confuse and disorient birds. Once drawn to cities and suburbs, birds often fly into buildings directly or circle them until they collapse from exhaustion. Up to one billion birds are lost to collision and exhaustion every year in North America. Dimming non-essential lighting during peak migration can help birds make it to their destinations safely.
