Every year, billions of birds migrate north in the spring and south in the fall. The majority of the birds fly at night, navigating using the Moon, stars and night sky. As they pass over big cities, they can become disoriented by bright artificial lights and sky glow. An estimated 600 million birds in the U.S. die each year from collisions with buildings. A recent study published by Cornell Lab of Ornithology ranked metropolitan areas in Missouri, Kansas and Illinois where, due to a combination of light pollution and geography, birds are at the greatest risk of becoming attracted to and disoriented by lights and crash into buildings.   

Organizations from the Heartland area of the USA are partnering together to create bird-friendly communities.  "Lights Out Heartland" is in good company becoming one more voice in dozens of "Lights Out" initiatives throughout the USA as outlined on the National Audubon Society website.
We hope that you will learn more about our program by reviewing our website and join our initiative to create bird-friendly communities.


The International Dark-Sky Association is pleased to announce a new partner in the critical work of protecting the night from light pollution: the National Audubon Society. The two organizations are an excellent fit! Encompassed in Audubon’s mission to protect birds and the places they need is the conservation of critical habitat, including the sky, creating a natural intersection with IDA’s focus on protecting the night from light pollution.   Learn more at www.darksky.org
