The Problem
"During their migratory season, millions of birds representing hundreds of species fly through our city on their way to their summer or winter homes. Lights from tall buildings can disrupt these migratory paths, causing birds to circle buildings repeatedly. As a result, many of them die from exhaustion or after colliding with a building.”  Lights Out Chicago

"Studies show an estimated 600 million birds a year die after hitting windows in the US and Canada. The problem is that windows reflect the sky and trees, and birds can't tell the difference. Lights left shining in glass buildings at night also draw birds, especially during migration periods -- like the one about to happen this fall. This happens with high-rise buildings, as well as, homes and offices." Source

The Problem
All across North America bird populations are in steep decline. “Migratory shorebirds, along with grassland birds that migrate from the Great Plains to Mexico, have lost on average almost 70% of their populations since 1970.

As we continue to use land for our own expansion, the breeding success of birds depends more and more upon our actions and willingness to support them in the urban, suburban and rural landscapes that we maintain around our homes and businesses.” Source
