10. Rose-breasted Grosbeak

I hate to see that. Your bird is a male Rose-breasted Grosbeak, a migratory songbird. Birds are unlikely to be OK after a collision like that.

Birds behave as if sheet glass is invisible to them. They strike clear and reflective window panes in all types of human-built structures worldwide with death rates in the billions every year.

The science documenting this significant scale of loss has been known for decades, but only recently have meaningful efforts to address the problem begun. In this book, Dr. Daniel Klem, Jr., describes and summarizes the challenges and solutions to this important conservation issue to protect our beloved birds. Architects, developers, legislators, legal professionals, urban planners, homeowners, and renters alike can use this book as a guide to creating a more bird-friendly world.

Unlike the complexities of other environmental challenges, such as climate change, this important conservation issue for birds and people can be solved right now. The blueprint to start is described within these pages and will serve as our guide in supporting this worthy effort.

Why Birds Hit Windows—and How You Can Help Prevent It

For birds, glass windows are worse than invisible. By reflecting foliage or sky, they look like inviting places to fly into. And because the sheer number of windows is so great, their toll on birds is huge. Up to about 1 billion birds die from window strikes in the U.S. each year, according to a 2014 study.

The good news is that you can greatly reduce the danger your home’s windows pose to birds with some simple remedies, according to Christine Sheppard, who directs the Bird Collisions Program of the American Bird Conservancy. The group offers extensive information on preventing collisions on its website. The Fatal Light Awareness Program also offers great information on preventing bird collisions.

What happens to birds that hit windows? Sadly, the bird often dies, even when it is only temporarily stunned and manages to fly away. Many times these birds die later from internal bleeding or bruising, especially on the brain. Daniel Klem of Muhlenberg College has researched this issue since the 1970s. He writes, “Glass is an indiscriminate killer that takes the fit as well as the unfit of a species’ population.”

Stop Birds Hitting Windows

Up to one one billion birds die each year in the United States when they hit glass windows, walls, and other structures, making this threat one of the most costly to bird populations.

But it's also a relatively easy problem to solve. We've made it even easier by evaluating and rounding up a list of products shown to reduce collisions on glass. Please have a look at the options below for homeowners and architects.

We present these products in two categories: (1) Those that have been tunnel tested by ABC and received a score of 70 or higher. These products are denoted with ABC's ‘Saves Birds' logo. (2) “Also Recommended” products that were tested using other, peer-reviewed protocols that we deem sufficient, or which have been shown by experienced monitors to demonstrate a significant reduction in collisions. Learn more about ABC's ratings.
