Why Birds Hit Glass

Birds don't understand the concept of glass as an invisible barrier that can also be a mirror. They take what they see literally: Glass appears to be habitat they can fly into, whether that habitat is reflected or visible through glass.


Continuing Education Classes

ABC offers bird-friendly building design courses for American Institute of Architects and LEED continuing education credit. Both in-person classes and webinars are available. To learn more about bird-safe buildings, contact Dr. Christine Sheppard by clicking below.


Legislation, Ordinances, and Code

Many local governments in the U.S. and Canada now require some level of bird-friendly design. We provide a model ordinance, a summary of existing bird-friendly building codes, guidance on writing and promoting legislation, and much more.

If you are designing a LEED-rated building, think about birds in the design phase and earn the popular Pilot Credit #55. We'll show you how!


Research & Testing

Learn more about ABC's research and evaluation program, which safely uses real birds to test bird-safe glass collision solutions and ensure their effectiveness.


From Bird Killer to Model Building

New York City's Jacob K. Javits Convention Center was a notorious source of bird collisions. When bird-friendly glass was installed as part of a major renovation to improve energy efficiency, collisions declined by more than 90 percent. Watch the video for a brief overview of this successful bird-strike prevention project.
