Light And Sound Pollution
What is light and sound pollution?
Light and sound pollution is an excess of anthropogenic (human caused) light and sound, that occurs beyond the natural levels. This is most commonly found in urban areas due to the high density of lights from buildings, street lights, cars, and so on.
Lit structures have caused bird fatalities due to collisions into the structure during migration
What can we do?
Bird researchers have begun raising awareness on the effects of light and sound pollution through citizen science programs. Your help in this citizen science program will help researchers better understand the impact on birds caused by light and sound. Once we understand how birds are affected, we can work towards a solution to help protect bird populations.
How is light and sound pollution harmful?
Human caused light and sound pose a major threat for bird populations, with the accelerating growth of urban development. Birds are particularly sensitive to light and sound pollution, which can alter their regular behavior. Lit structures have caused bird fatalities due to collisions into the structure during migration.
Changes to natural lighting have also caused changes to health, mating and predation. While changes to natural sound levels have affected bird communication, mating, and social behavior.
