Every year in the United States, between 365 million and 988 million birds are killed after colliding with buildings.

Contrary to conventional wisdom, the greatest mortality does not occur at gleaming, glass-covered high-rises, but at shorter buildings, and especially at residences.

This means that homeowners across the country have a great opportunity: By decreasing the number of birds that strike the windows of our residences, we can dramatically improve the state of our birds. 

Indeed, making windows safe is one of seven simple actions that scientists at the Cornell Lab of Ornithology say will dramatically improve the state of North American’s birds. 

In this presentation, Chuck Hagner will describe proven strategies and effective products that homeowners can use to keep birds from striking the windows of their home. 

Hagner is the author of the American Birding Association Field Guide to Birds of Wisconsinand the director of Bird City Wisconsin. From 2001 to 2017, he was the editor-in-chief of nationally distributed BirdWatching magazine. He is board chair of the Western Great Lakes Bird and Bat Observatory.
