Windows are reflectors. Trees and all other foliage are reflected in them and invite birds to fly right into the glass. This reflection takes a high toll on birds as there are so many windows in their environment. Studies show that more than one billion birds die every year in the United States resulting from window strikes.
When a bird collides with a window, it will either die immediately or be temporarily stunned and manage to fly away. Even though you see a bird fly away, this does not mean it is unharmed. Most times when a bird collides with a window, it will die later from internal bruising or bleeding. The most damage occurs to their brain, and typically results in death at a later time.
Why Birds Fly Into Windows
Two main reasons or types of window collisions are nighttime and daytime. At night, a nocturnal migrant, which includes most of our songbirds, will fly into a window because they are attracted to the light. Sometimes the collisions are by chance, but most often the lights lure the birds to their death.
Nighttime lights divert nocturnal migrants from their original path, especially in foggy conditions. If there are lights in a low-ceiling structure, you will see birds milling about, colliding with each other or into the structure. Daytime collisions occur either because the foliage is reflected or they see the foliage on the other side of the glass, such as potted plants. Seeing the foliage makes the bird think they have a clear flight path right to it.
Another reason birds may fly into your windows as they see themselves and attack it. This problem is high during the spring months when birds are more territorial. It does not necessarily injure the bird if they peck on your window thinking they are warding off a potential threat, but it can become annoying.
How to Prevent Birds From Flying Into Your Windows
The first step is to go outside and look at your windows from a bird’s point of view. Whatever you see reflecting in your windows is what the birds are going to see. Windows that are especially dangerous are the large picture windows or windows that have been paired at right angles to each other.
There is something you can do to reduce or prevent birds from flying into your windows. The American Bird Conservancy has put together some simple remedies for homeowners, or anyone with windows on their structure to prevent bird collisions:
1. To deter small birds from colliding with your windows, you can make vertical markings on them that are no more than four inches apart. Horizontal markings should be no more than two inches apart. The markings should cover the entire window area. You will want to apply these markings to the outside of your glass. The markings can be made with either tempera paint or soap which are both inexpensive solutions.
2. Other ideas to use on your windows if you are having a problem with collisions.
Decals can be effective if you space them closely (Hawk decals will do little to scare birds)
ABC bird tape is a long-lasting solution and easy to apply
Zen curtains are spaced ropes that hang down over windows and work as well as decals or tape
Screens are very effective
Netting will cover the entire glass on the outside and will bounce birds who attempt to fly into the window
A transparent film will allow you to see outside but make the window appear opaque to the birds
