Over 1,000 birds a year die from smashing into windows.

 Bird-window collisions are a significant problem for many bird species, with an estimated one billion birds dying from such collisions in the United States alone each year. The problem is caused by the reflection of the sky or trees in the windows, which can cause birds to fly into the glass. This can happen to birds of all ages and sizes, and can be particularly devastating for migrating birds.

Windows on buildings and homes are the most common cause of bird-window collisions, but they can also occur at other types of structures such as wind turbines, power transmission lines, and skyscrapers. Birds are attracted to the reflection of their natural habitat in the glass, and they may not be able to see the obstacle until it is too late.

There are several things that can be done to prevent bird-window collisions. One simple solution is to apply a visible pattern, such as decals or window film, to the windows. These patterns can make the glass visible to birds, helping them to avoid flying into it. Another solution is to install bird-friendly screens on windows, which can help to break up the reflection and make it less attractive to birds.

Another way to reduce bird-window collision is to plant more bushes, flowers and trees near the windows, so that the birds have a better chance to see the windows. This can also provide the birds with a safe place to hide if they do fly into the windows.

It's also important to keep the lights off or dimmed during night time for migratory species since it disorientates the birds and attracts them towards the light source.

Bird-window collisions are a serious problem, but with a little effort and creativity, we can reduce the number of birds killed by these collisions. By taking simple steps to make our windows more visible to birds, we can help to protect these beautiful creatures and preserve their populations for future generations.
