"Collisions Between Birds and Windows: A Vital Conservation Issue”
Speaker/Guide: Dan Klem, Jr.
Location: Smith Wilkes Hall
Years of study reveal a number of historic accounts of birds striking windows, with investigations that document and validate that birds behave as if clear and reflective windows are invisible to them. A billion birds annually are estimated to die striking windows in the U.S. alone. With the exception of habitat destruction, and losses to domestic cats, more birds are annually killed flying into windows than any other human-associated avian mortality factor; exponentially more than the higher image attrition attributable to communication towers, oil spills, pesticides and poisons, vehicles, and wind turbines. The results of research addressing the evaluation of preventing bird-window collisions have revealed several effective methods, but additional education and short- and long-term solutions are needed to ensure the human-built environment is safe for birds the world over.
Daniel Klem, Jr. is Professor of Biology and Sarkis Acopian Professor of Ornithology and Conservation Biology at Muhlenberg College in Allentown, PA. Considered the foremost scientific expert on avian mortality attributable to windows, he studies, writes, and teaches about the threat that sheet glass and plastic pose to birds. He is supported by research grants from government agencies, NGO’s, and industry to evaluate methods to prevent these avian deaths by retrofitting existing windows and developing new bird-safe panes for remodeling and new construction. His research has resulted in U.S. patents to guide the development of novel films and windows using ultraviolet signals that birds see and humans do not.
