WORLD MIGRATORY BIRD DAY 2022
DIMMING LIGHTS FOR NIGHT BIRDS
Light pollution attracts and disorients nocturnal migratory birds, making them more likely to land in areas where they are more vulnerable to collisions and other hazards. In the United States alone, at least 100 million birds are killed each year by colliding with buildings. Artificial light also affects birds in the breeding and winter seasons, disrupting feeding and other vital behaviors. Because artificial light affects birds in so many ways, it is impossible to know how many birds are affected by light pollution each year around the world. Throughout the year we will spread the message to “dim the lights for birds at night” and highlight steps that people, communities and governments can take to reduce the impact of light pollution on the birds we share.
