The sound of a bird window strike is horrible. There are many reasons birds fly into windows, but there is a simple, highly effective DIY solution to prevent bird injury or death.

The video below shows why bird window strikes happen and how to prevent them.

The problem:

Birds window strikes, where birds fly into the window glass, is the number one cause of bird mortality in North America. There are a number of reasons birds crash into windows, but many of those birds will not survive. More often though, you might not even realize it has happened because the bird was injured or killed, and a then predator or scavenger dragged the poor bird away.

A bird colliding with our window happened again recently at our house, and I knew something had to be done. Under those circumstances, I began to research ways to prevent these tragedies.

Overall, nothing met my criteria of being aesthetically pleasing, in addition to being reasonably cost effective. Many solutions involve stickers adhered to window glass, but these are visually intrusive and really interfere with our ability to view our wonderful flying friends out our windows. Another solution incorporates replacement glass with anti-reflective properties, but that’s a very expensive remedy.

Window strikes are preventable

The solution:

Surprisingly, an undeniably effective method was developed decades ago, although I had not heard of it until now. As a matter of fact, it was in the 1980s when the Acopian family of engineers and naturalists invented a method for preventing bird window collisions.

They call them BirdSavers, and are also referred to as “Zen Wind Curtains” due to the calming effect of the cords swaying in the breeze. Importantly, they have not only been scientifically proven effective, but they are great looking too! Win—win for the birds AND us!

It turns out they are super easy to make, but for those that can’t or don’t want to make them, they can be purchased on the website. 

There’s a great deal of information on the website for making BirdSavers for yourself as a fun and easy DIY project. In fact, they’re perfect for having the kids or grandkids join in! You can also see where BirdSavers have been installed and are saving birds worldwide on their “Where are BirdSavers?” page and interactive map. If you’ve installed BirdSavers (purchased or DIY), you too can have your location added to the constantly growing list!

The video above shows my method for making these BirdSavers out of metal for a long-lasting, elegant solution. The result is, they look great from the inside and outside of the house or commercial building, and they don’t interfere with the view out of the windows.

Prevent needless deaths of our flying friends!
