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.

Follow a little songbird as the bright lights lure it into the dangers of the city. The threats it faces are common to migratory birds trying to navigate urban environments. By turning off non-essential lighting at night, birds are less likely to become disoriented on their long journeys.

Light pollution and its impact on migratory birds is the central theme of World Migratory Bird Day 2022, a global campaign that aims to raise awareness about migratory birds and the need for international cooperation to conserve them. The 2022 campaign slogan is "Dark nights, safe migrations!"
