If you can’t turn off your indoor lights, closing your blinds or curtains will also help protect birds during migration. In order to protect birds, Audubon Societies asks people and cities to go “lights out.”Īll you have to do is turn off your lights, specifically outdoor lighting, from 11 p.m. We know that several billion birds hit built infrastructure and don't survive,” Gallitano said. “They see a light, they might see the reflection of a tree and they think they can fly through a window. Gallitano says migrating birds face one specific threat, especially at night. Gallitano is a volunteer with the Wake Audubon Society and she’s worried birds will become even harder to find as their homes disappear and are replaced with buildings. If you can’t turn off your indoor lights, closing blinds or curtains will also helpĪfter four decades of bird watching, Lena Gallitano has learned a thing or two.
The Wake Audubon Society is encouraging people to turn off excess lighting, specifically outdoors, during migration.Window collisions kill up to one billion birds each year.Birds can become disoriented by bright artificial lights and fly into windows or buildings.The majority of migrating birds fly at night between March 15 and May 31, and September 10 through November 30.Assessing these landscape and architectural factors can not only allow us to focus efforts on mitigation for these buildings but can help us to predict the likelihood of a given building being problematic and requiring extra monitoring efforts. Most of the collisions found are migratory species while traveling between wintering and breeding grounds. Over the course of four semesters of recording, 445 window strikes have been documented on campus by the team, 339 of which have been fatal.
The Lights Out Buckeyes team monitors campus four times a week, covering the entirety of campus twice per week. These factors include the amount of tree cover, percentage and area of glass on buildings, as well as location on campus. The Lights Out Buckeyes team seeks to better understand specific factors causing birds to collide with a given building. Using data collected by myself and fellow members of the Lights Out Buckeyes team (OSU's avian window strike monitoring team), these smaller scale factors were further explored. Many of the fine scale factors leading to window collisions have not been fully determined. Many efforts have begun across the country to more accurately assess the impact and provide rehabilitation for window strike victims that survive. Window collisions due to both glass reflectivity and lights at night are the second leading cause of bird death in the United States (Klem 1990).
