Fort Collins, Colo. (August 30, 2021)—Over the next two nights, 9.5 million birds are expected to migrate south over Colorado, according to the CSU Aeroeco Lab. Although it may still be summer to people, it’s not to birds. Fall migration is underway and the peak is expected to occur over the next month. During this spectacular and perilous journey, birds need a simple favor. They need us to turn off our lights.
To take advantage of calmer air and protection from predators, most birds migrate at night. To navigate, they rely on cues in the night sky. Artificial light—ever increasing with Colorado’s population—poses a serious threat to migratory birds. “Outdoor lights attract and disorient birds. Some birds collide with buildings, while others exhaust themselves in confusion,” said Zach Hutchinson, community science coordinator for Audubon Rockies. Building collisions kill millions of birds each year, and light pollution is an important contributor.
To bring attention to this issue, Audubon Rockies, the Colorado chapter of the International Dark-sky Association, and Denver Audubon teamed up last spring to launch Lights Out Colorado, a program that aims to help Coloradans save millions of migrating birds.
“The good news is that it’s very easy to do your part. Simply turning off or shielding your outdoor lights during migration can save birds’ lives,” said Suzy Hiskey, conservation coordinator for Denver Audubon. To maximize their impact, Coloradans should turn off their lights as early in the evening as possible during September.
Lights Out Colorado provides two simple steps people can take to have a big impact on birds:
- Shield outdoor lights to prevent light from being emitted upwards.
- Turn off lights by midnight during bird migration seasons (April-May and August-September).
“In addition to helping birds, reducing light pollution has the benefits of lowering energy usage, saving money, and preserving night skies for everyone,” said Richard O’Brien, International Dark-sky Association Colorado chapter member.
To learn how to help birds in their communities, Colorado residents should visit the Lights out Colorado website, where they can pledge to help migratory birds and encourage local governments and businesses to take action.
