Mortality Threats to Birds - Collisions

... Up to Parent Page Towers Buildings Wind Farms Power Lines

In recent years, the problem of bird strikes with buildings, towers, wind turbines, and overhead powerlines has become of increasing concern to conservationists. Hundreds of millions of birds - mostly night-migrating songbirds - die each year in collisions with such structures, including many species on ABC/Audubon WatchList. Lighting on these structures - both for the purposes of aviation and decoration - appears to be a primary causal factor, and efforts have been made to limit or change lighting regimes to minimize the hazard.

American Bird Conservancy continues to be a leading force in ongoing efforts to protect birds from collisions, working with industry representatives, the federal government, and other conservation groups. Click on one of the pictures below for more information on specific threats to birds.
