FORT COLLINS, Colo. (April 1, 2022) – Governor Polis has April 2022 as Lights Off for Bird Migration Month, effective today. "In the coming weeks, tens of millions of birds - from statuesque sandhill cranes to smaller meadowlarks and bluebirds - will pass through our state, marking a yearly pilgrimage that Coloradans have marveled at for generations. As we celebrate Bird Migration Month this April, the Polis-Primavera administration is proud to partner with Colorado's Լ����Ƶ community to ensure that our magnificent bird populations continue to thrive, by preserving and protecting the precious natural resources these species depend on," said Lt. Governor Dianne Primavera.  

While Coloradans celebrate the return of migratory birds, one key fact is often overlooked: most birds migrate nocturnally. “To avoid predators and take advantage of calmer air, 80 percent of migratory birds migrate at night,” said Zach Hutchinson, community science coordinator for Լ����Ƶ Rockies.

Unfortunately, Colorado’s rapid development is causing the deaths of thousands to millions of these birds. According to Governor Polis’s proclamation, “During nocturnal migration, intense artificial lights can cause birds to collide with windows or walls, or cause them to circle in confusion, leaving them weak and vulnerable during their arduous journeys.” 

Governor Polis proclaimed Lights Off for Bird Migration Month to raise awareness for this issue and its solutions. Fortunately, reducing light pollution is an easy action that every Coloradan can take to help birds migrate safely. “Because of the immense scale of development in Colorado, we need as many people as possible to help by turning off and shielding their lights,” said Richard O’Brien, International Dark-Sky Association Colorado chapter member.

A year ago, the Colorado chapter of the International Dark-Sky Association, Լ����Ƶ Rockies, and Denver Լ����Ƶ partnered to create, a statewide awareness campaign. It encourages businesses and community members to turn off all non-essential outdoor lights to reduce light pollution. Doing so provides safer migration routes for birds. On the campaign’s website, Coloradans can take a pledge to help migratory birds, learn techniques for shielding lights, and find resources for contacting their local government and businesses. In celebration of spring migration, Lights Out Colorado is holding a free about bird migration, featuring renowned Colorado State University scientist Kyle Horton.

“This April and May, millions of birds will fly to and through Colorado. The challenges they face from light pollution have been overlooked, but Governor Polis’s proclamation helps drive the action that the birds need,” said Karl Brummert, executive director of Denver Լ����Ƶ. With it, Colorado joins a growing number of cities and states across the country that are trying to help birds migrate safely.
