Want to Know How to Stop Birds from Flying into Windows? Birds often fly into windows because they see reflections of the sky, trees, or themselves and mistake it for open space. Unfortunately, these collisions can seriously injure or kill birds. Luckily, there are effective ways to prevent this from happening. One of the simplest solutions is to break up window reflections. Apply window decals, stickers, or tape in patterns spaced 2 to 4 inches apart. This signals to birds that the surface is solid. You can also use netting, screens, or exterior shutters to block reflections while still allowing light in.
