Did you know?

Light Pollution is a Problem for Birds

Light pollution, the inappropriate use of artificial lights at night, disorients the many migratory birds that travel at night.

Much like insects to a light bulb, light from towns, suburbs and cities that spill into the skies attract birds, drawing them in.

Birds exhaust themselves while navigating these unfamiliar spaces. In this confused state, they strike lit and reflective windows.

Between 365 million and 1 billion birds die in these strike, or collisions, each year in North America

There’s an easy solution

But we need your help

Visit downtown SLC for the Salt Lake Avian Collision Survey

Urban areas are places that can pose the greatest risk to nocturnal migrating birds. Looking for bird collisions downtown can help us understand the magnitude of the issue and coordinate an appropriate response. Apply today.

Self-report bird collisions in your area

Do you live outside of downtown Salt Lake? We can still use your help. Reports birds that you think died due to striking a building. Report a bird strike.
