Artificial light at night (ALAN) on tall or upward-pointed lighting installations affects the flight behavior of night-migrating birds. Every night during the spring and fall migration seasons, thousands of birds are killed when they crash into illuminated windows, disoriented by the light. Watch our seminar on bird/glass collisions: Use newer technology to avoid over-lighting areas. Our work has been featured in publications by the BBC, Washington Post, and Huffington Post. Install automatic controls and sensors to turn off lights not in use. Lights Out DC is patterned after highly successful lights-out programs in Chicago, Toronto, Boston, New York City, and Baltimore, to name a few. This tool depicts migration patterns in near real time or as a summary of a whole night after nocturnal periods end (2021-present. The statistics are used to convince building owners and managers to adopt light abatement procedures for the sake of migrating birds. The new BirdCast Migration Dashboard provides summaries of radar-based measurements of nocturnal bird migration, including estimates of the total number of birds migrating, their directions, speeds, and altitudes. Injured birds are monitored and released (if recovered) or taken to City Wildlife’s rehabilitation center if their injuries are more severe. The blow can be fatal or it can leave the birds injured and vulnerable to predators and street sweepers.ĭuring migratory seasons, Lights Out DC volunteers walk a four-mile route in downtown Washington to inspect buildings and collect dead or injured migratory birds that have collided with glass. Passing over cities, they are often attracted to artificial lights and frequently strike transparent or reflective windows. Most neo-tropical songbirds migrate at night to avoid turbulence in the air and they navigate by the stars. ![]() In urban areas, the problem worsens during periods of migration. ![]() Collisions with buildings kill more birds than any other single human factor besides habitat loss and domestic cats. ![]()
