Most homes in the U.S. are estimated to kill a few birds every year. Fortunately, there are easy solutions to solve the problem of birds hitting windows!
Almost 50 percent of bird collision mortality happens on home windows, and the most likely place for birds hitting windows is near bird feeders.
If you have outside screens on all your windows, you’re already on your way to having a bird-friendly home. The patterns made by mullions in colonial windows also reduce the likelihood of collisions.
Luckily, there’s a lot you can do to make your house and yard safer for birds. See our Bird-Smart Glass page for a variety of easy solutions.
Research has identified ways to alert birds to windows. The easiest way to stop birds hitting windows is to apply visible patterns to the outside of windows.

Because some windows are difficult to access from the outside, such as in a high-rise building, a frequent question is, “Will putting something on the inside of my windows work for birds?”
Only a test can provide the answer, because different kinds of glass have different levels of reflections. Put a sample of your proposed solution, or a sticky note or piece of adhesive tape, on the inside of the window and then look from the outside every hour or two, starting in the early morning.
If you can clearly see your test material most of the time, birds will, too, and you can use an “inside” solution. However, in many cases, reflections will mask the view during part or all of the day, and you’ll need a solution on the outside of your windows. Solutions like tape or decals must also be carefully spaced to effectively stop birds hitting windows.
