Dr. Daniel Klem – Bird/Window Collisions: Historical Research and Contemporary Solutions


DATE: October 5, 2017
TIME: 7.30pm
LOCATION: Auditorium at the Academy of Natural Sciences of Drexel University
1900 Benjamin Franklin Parkway Philadelphia, PA 19103 United States

Keynote Speaker: Dr. Daniel Klem, Jr. Ph.D., D.Sc.

Daniel Klem, Jr., Ph.D., D.Sc. Daniel Klem, Jr. is Sarkis Acopian Professor of Ornithology and Conservation Biology at Muhlenberg College in Allentown, Pennsylvania. Dr. Klem obtained his B.Sc. at Wilkes University and his M.Sc. at Hofstra University. He served in the US military served during the Vietnam War, and was awarded the Bronze Star Medal. He subsequently obtained his doctorate from Southern Illinois University.

Among other diverse avian investigations, for 44 years and continuing to the present he studies, writes, and teaches about the threat that sheet glass and plastic pose to birds. No other scientist has comprehensively studied and published research results documenting and preventing the lethal threat that human structures pose to birds. In his 1990 papers “Bird injuries, cause of death, and recuperation from collisions with windows” and “Collisions between birds and windows: mortality and prevention”, he calculated that between 100 million and 1 billion birds are killed, annually, in the United States alone, by flying into windows.

His research has influenced the design of buildings, not least the Niagara Falls State Park Observation Tower, on which he was a design consultant. He holds several US patents relating to windows design. He is motivated by available and growing evidence that bird-building collisions are an important wildlife conservation, building industry, and animal welfare issue for birds and people worldwide. His presentation will cover the basics, and will emphasize the impact of individual homes, commercial buildings and cities. He will than talk personally about the history of the topic and end with the floor open to questions and comments.
