Preventing Bird-Window Collisions (In-Person & Live-Streamed Talk)

Annual bird mortality resulting from window collisions in the U.S. is estimated to be between 365 million and 988 million birds (Loss et al. 2014) with some annual estimates as high as 500 million birds (Klem et al. 2009, Klem et al. 2024). Birds are easily deceived by reflected images of habitat and sky on windows installed in the conventional vertical position and can strike these windows, leading to injury or mortality. However, there are many different solutions that can be implemented.

For new or remodeled infrastructure, designers can use features such as overhangs, shutters, mesh, and awnings, or install windows at an angle to reduce glass reflections. For existing infrastructure installing specific “bird friendly glass” or reducing the exterior reflectivity of windows by applying bird collision deterrents such as window film or other exterior mountings that create a pattern to break up reflective surfaces are some of the best options. Additionally, turning off, dimming, or installing motion activated lights near windows at night can also reduce impacts to birds.

We will discuss the issue of bird window collisions and how we as a community and individuals can protect birds from this threat.
