Solid Air, Invisible Killer: Saving Billions of Birds from Windows: A Presentation by Dr. Daniel Klem, Jr. (Registration Required)

Valley Forge Audubon Society, in conjunction with the John James Audubon Center, welcomes Dr. Daniel Klem, Jr., Sarkis Acopian Professor of Ornithology and Conservation Biology at Muhlenberg College and world expert on bird collisions with glass.

An alarming number of birds die every year after flying into glass they cannot see, because clear and reflective windows are invisible to them.  In fact, one of the principal mortality sources cited as contributing to the decline of a third of the North American bird population since 1970 is window strikes.

Dr. Klem will delve into the cause and breadth of this universal problem and share how we can take action to make the human-built environment safer for birds every day.

Following Dr. Klem’s presentation, Vince Smith, Valley Forge Audubon Society chapter president, and Leigh Altadonna, Wyncote Audubon Society chapter president, will discuss the work of Bird Safe Philly, a vital Philadelphia-based partnership that aims to create safe spaces for birds by developing awareness of the issue of bird collisions and implementing solutions in partnership with the Philadelphia community.

Space is limited. Register here for this free in-person event.

COVID-19 safety measures:  Current Montgomery County guidelines require that masks be worn inside all County buildings.  This program will take place in the Pavilion and additional spacing will be provided between seats.
