Project Safe Flight Atlanta, a conservation and engagement effort to understand the issue of bird-building collisions in metro-Atlanta, uses volunteers to patrol selected routes during peak bird migration periods. They collect birds that have died or have been injured after colliding with buildings. Since Project Safe Flight Atlanta launched in 2015, more than 500 birds of 71 different species have been collected.
Current research estimates that between 350 million and 1 billion birds perish each year from colliding with buildings in the United States. Bright nighttime lights can disorient migrating birds or trap them in upward-facing beams of light where they die of exhaustion or land in dangerous areas. During daylight hours, birds struggle with reflective surfaces when they stop to feed or rest, as they are unable to distinguish between a reflection and an open flyway.
