Up to one billion birds collide with glass and are killed every year in the U.S., according to the American Bird Conservancy. A group in Washington, D.C., including City Wildlife, is conducting a “lights out” fall monitoring project, gathering data on building strikes by looking for dead or injured birds along preset routes in the city early in the morning. Data can help convince managers at problem buildings and government officials to reduce bird collisions. You can learn more here. Some Fairfax County officials recently met with American Bird Conservancy experts to learn about bird-friendly building design. If anyone would like to conduct a similar project in Northern Virginia, contact Glenda Booth.
