Migratory Birds

Light Einstein Exploration Station
The above shows what a birding association collected off the streets of downtown Toronto after just one night during migration season.

In the U.S. alone, between 100 million to 1 billion migratory birds die each year when light pollution disorients them or causes them to fly into buildings. Most migratory birds fly at night, relying on the light of the moon and stars to help them navigate. Bright city lights are confused for the celestial lights above.

Those who escape the fatal crash may spend their energy flying around, calling for help, and making themselves vulnerable to other urban threats.
