The Museum’s staff is thrilled to have recently become a partner of Lights Out Bend, a volunteer-operated education and advocacy program that seeks to highlight the issue of light pollution and inspire the community to reduce light pollution. In becoming partners, we join fellow local organizations keen to make a difference. This includes the Deschutes Public Library, East Cascades Audubon Society and Ruffwear.
What is light pollution and why should we care? Simply put, light pollution is the inappropriate or excessive use of artificial light, and human activities are lighting our night sky like never before. You’ve probably seen many businesses and homes leaving lights on at night. While this may seem harmless, it has major implications for native wildlife species. They evolved with predictable phases of light and dark, and many species are guided by celestial sources of light—such as the moon, stars and planets. Artificial lights interfere with these natural rhythms and behaviors. Bats, birds, moths and other species may suffer reduced hunting success, collisions with windows, disorientation and numerous other problems. Light pollution puts lives on the line.
Luckily, the solution comes with a simple flick of a switch! By turning off unnecessary lights, using motion sensor lights or lower intensity bulbs or installing fixtures that don’t direct light up into the night sky, we can improve the lives of birds and animals with whom we share the High Desert. We can also close our curtains at night to reduce the amount of light that can escape to the outside environment. While these actions are meaningful year round, they are particularly important during spring and fall migratory seasons.
Protecting the starry night sky saves wildlife. We also benefit from energy savings and a better view of the stars. It may even improve our health, as electric lights are thought to influence our own biological clocks. The Museum’s staff is committed to switching off all unnecessary lights at night. We hope you’ll join us.
