Daniel Klem, Sarkis Acopian Professor of Ornithology at Muhlenberg College, shares how decades of research have given us the knowledge on how to reduce or eliminate hundreds of millions of bird deaths each year due to collisions with glass.

SOLID AIR

Dr. Klem captures over four decades of research experience and pleas for change.

As useful and attractive as sheet glass and plastic are in human buildings, the windows they make are indiscriminately lethal and devastating to free-flying birds.

This book describes the cause and breadth of this universal problem and how to solve it. Detailed objective observations and experiments reveal that birds behave as if clear and reflective windows are invisible to them. Alarmingly, among the dead are the fittest individuals in species populations.

Science has documented that a decline of a third of the annual North American bird population, approximately 3 billion individuals, has occurred since 1970, and one of the principal mortality sources is windows. However agreeable and possible, citizens the world over are asked to take action and join in making the human built environment safe for bird life as one of Nature’s most beautiful, useful, and spiritually uplifting creations of planet Earth.

Unlike the complexities of other environmental challenges, such as climate change, this important conservation issue for birds and people can be solved, and the means to do so are described within the pages of this work to guide this worthy effort.
