Lights Out participation helps to dramatically reduce collisions and terminal exhaustion, protecting our feathered friends. Sadly, up to one billion birds are lost to collision every year across North America. Once trapped among windowed cities, birds either hit buildings directly or circle them until they collapse from exhaustion. When migrating birds fly over brightly lit homes and buildings, the skyglow (light pollution) drowns out the stars, confusing and disorienting them into urban areas. Every spring and fall, birds soar across the Dakotas in large flocks, filling the night sky with a superhighway of birds! By dimming non-essential lighting during peak spring and fall migration, we can help birds make it to their destinations safely. Many of these birds, some weighing as little as an ounce, make their remarkable bi-annual migration at night, all while using the earth's magnetic field, moon, and stars to navigate their journey. Your tax-deductible gift makes these shows possible.Every year, millions of birds migrate across North and South Dakota, often flying thousands of miles! From Sandhill Cranes, ducks, and geese, to songbirds, like the Black-and-white warbler, the prairies, wetlands, and woodlands of the Dakotas provide critical habitat for birds to rest, refuel, and seek shelter.

Research: Study Names Top Cities Emitting Light that Endangers Migratory Birds Tenijah speaks with Julia Wang, project leader at BirdCast and the Lights Out Texas campaign at the Cornell Lab of Ornithology. BirdCast, a tool that can forecast the peak migration nights of the season, is helping these programs make a greater impact. “Lights Out” programs get cities and their residents to turn off nonessential lighting during migration seasons which can help make their journeys a little easier (and save energy!). Drawn off course by bright, artificial lighting, birds can wind up fatally colliding with windows or wasting precious time and energy that they need to survive. Migratory birds use starlight to find their way on their long journeys - which makes light pollution a serious threat.
