The American landscape has changed dramatically in the past few hundred years. For birds, this means that migratory pathways utilized for millenia are now unrecognizable, filled with buildings, roads, lights, and other changes. Among the most insidious new threats on landscape is glass windows, which trick birds with both reflectivity and transparency. It's estimated that between 365 million and 988 million birds die each year after hitting glass windows. Learn from Nick Lund, Advocacy and Outreach Manager at Maine Audubon, about the work that Maine Audubon and its partners in BirdSafe Maine are doing to understand the problem and raise awareness with homeowners, architects, and lawmakers.
