Why Birds Hit Windows—And How You Can Help Prevent It. For birds glass windows are more than invisibility. By reflecting foliage or the sky, they appear as inviting spots to fly through. Because the sheer volume of windows the cost to birds is enormous. Around 1 billion birds are kill by window-related injuries within the U.S. each year,

The positive side lies in the fact that you can drastically minimize the risk windows of your house can pose to birds by using easy remedies, adequate to Christine Sheppard who is the director of the Bird Collisions Program of the American Bird Conservancy. The organization offers an extensive guideline on how to avoid collisions on its website. It also has the The Fatal Lighting Awareness Program also provides valuable tips on how to avoid collisions with birds.

How do birds react to the impact that strike windows? Unfortunately, the bird frequently is kill, even though it is just temporarily stunned and then flies away. Most often, these birds die from the internal bleeding, or from bruising especially around the brain. Daniel Klem of Muhlenberg College has been studying this subject from the 70s. He wrote “Glass is an indiscriminate killer that takes the fit as well as the unfit of a species’ population.”

Why Birds Collide With Windows

Why Birds Collide With Windows

There are two kinds that window crashes occur: nighttime and daytime. When it is daylight, birds fly into windows because they can see reflections of plantsor view through the glass to potted plants or the vegetation on the opposite side. At night, nocturnal migratory birds (including the majority of songbirds) smash into windows due to their flight into windows that are lit.

In a way that is not fully understood the lights divert nocturnal migratory birds from their path of travel and, in particular, during low-ceiling fog-like conditions. In the area that is lit the birds flit around and sometimes cross paths with another or the light structure. A hazard that follows those displaced by lighting in urban areas may choose to roost at a safe distance and then become susceptible to the reflections of windows in the daytime the next day. This is where the BirdCast Project as well as the Fatal Light Awareness Program are the desirable sources for information on the issue.

There’s an extra reason: birds may observe their reflections through windows and then strike it. It’s most frequent in spring, when territoriality is at its peak. While it may be a nuisance to homeowners, it’s not an issue for the bird’s life. The majority of the solutions suggested here for window smacks can also benefit to solve the issue of a bird slashing its reflection.

How To Safeguard Your Windows For Birds

Begin by identifying the windows that could be dangerous such as huge picture windows windows that are paired that are at an angle to each the other, or windows that have feeders outside. Look outside and observe your window from the bird’s view of perspective. If you can see branches or the sky shining from the window. Those are what birds be able to see as well. The previous recommendations on feeders’ safe distances from the windows have been believe to be accurate, Sheppard says. “If you’ve got windows near a bird feeder. You should make them bird friendly and don’t fear about how far away they are.”

Treatments For Existing Windows

To discourage small birds the vertical marks on windows should be ideally place on 2 inches by 2 inches. (This can make windows safe for the smallest of birds like hummingbirds, siskins, gnatcatchers and others.) Any marking technique should be applied to exterior part of the windows.

  • Paint or soap. Mark the outside of your window with tempera paint or soap which is affordable and long-lasting. It is possible to use either the grid that measures 2 inches by two inches (see above) or you can get imaginative and create patterns together paint or designs on your windows.
  • Decals. Put decals, stickers the suncatchers, mylar strips masking tape or other items (even sticky notepads) onto the exterior on the windows. They only work when they are place in a very tight space (see the previous paragraph). The silhouettes of hawks are not satisfying to stop bird strikes. Remember: placing only one or two window stickers on a huge window will not stop collisions. They must cover the majority of the glass and fill in the space between them that is too narrow for birds to maneuver through.
  • Dot patterns as well as Tape. Long-lasting tape products make it easier to ensure the proper spacing of dots across your windows. The products available from Feather Friendly can be use to help to prevent collisions.
  • Acopian Bird Savers. Also referred to as “zen curtains,” these close-spaced ropes hang on windows. They perform the same function as tape or decals, but are less difficult to install and also look attractive. They’re extremely efficient and are what that we employ to protect windows in Cornell Lab. Cornell Lab headquarters. It is possible to purchase them that will fit in your windows, or build ones of your own.
  • Screens. Installing mosquito screens on your windows can be extremely effective as long as they are place on an outside edge of your window, and are covering the entire window.
  • Netting. Cover the glass on the outside with netting, at minimum 3 inches away from the glass. It should be and taut satisfying to bounce off birds before they strike. Small mesh nets (around 5/8′ (or 1.6 centimeters) is best to assure that birds don’t get their heads and bodies caught, but bounce away without harm. It is possible to mount the netting on frames, such as the frame for a storm-window, which allows ease of removal and installation.
  • Transparent film that is one-way. Products such as Collidkescape let people on the inside to look outside however they make windows appear opaque on the outside. They may decrease sunlight through your window (this will also lower the cost of cooling), compatible to Sheppard.

New Homes And Remodels

  • Install shutters on the outside and make sure they are close when you’re not there or enjoying the view or light. (These are huge energy savers as well!)
  • Install sun shades on the outside or awnings on windows to block reflections from sunlight. Remotely controlled shades are readily available.
  • When building a new house or building new windows, think about windows with screens all around the glass.
  • Install vertical blinds in the interior and make sure that the slats are only half-open.
  • Beware of visual pathways to the skies and greenery. Window windows that are bright that are located opposite to your picture window can create the appearance of an open space to the opposite side. The closing of a shade for windows or an entrance between rooms may occasionally solve this problem.

Lights Out

The Lights Out initiative is growing within U.S. Cities which include Dallas, Houston, Philadelphia and New York. The dazzling light from the streetlights and offices in urban areas is particularly dangerous because it can entice birds to change the path, slowing their movements and making them more vulnerable to collisions with windows. Switching off lights that are not essential as well as installing lighting that faces downwards are a simple way to minimize the danger of artificial light in the night. It is nevertheless advisable to protect yourself from window collisions together any of these strategies, particularly for homeowners.



If a bird is struck by the window and is injured. Its accurate chance of recovering is to seek benefit from an animal rehabilitation center immediately. Victims of window collisions may suffer from internal and pain injuries that aren’t apparent initially, but they will get worse as time passes. They are at risk of pedestrians and predators when left unattended. If you see an animal shivering from an accident with a window This is what you should do:

You should try to capture and hold it. The bird should be approach from behind, and apply two hands to protect it. The bird might flutter around or call out, so don’t be frightened. Be aware that birds of small size are incredibly fragile, so avoid closing your hands or fingers around their bodies. Hold the bird with care, but secure.

Choose an appropriate container like unwaxed bags of paper or a small cardboard boxes covered with tissues or a towel for the bird to grasp. Place the container closed in a dark, quiet area warm, and far from pets and children.

Don’t handle, feed or drink the bird after it is inside the container. Be aware that wild birds could see humans as predators, therefore try not to put too much stress on the bird.

Look for a rehabber close to your home (via the web-based directory) and reach them for more information. If you aren’t able to take the bird away contact the wildlife rehab facility know, and they might be able offer alternative alternatives.

In the event that a facility asks you to release the bird then bring it to a wooded area (or any other appropriate habitat in the particular species) in a safe distance from any buildings. Prior to releasing the bird remain away from plants or trees to be able to observe the bird’s movements. The bag or box should be pointed towards the direction of vegetation, and then slowly open the lid. If the bird is unable to fly as well, you can try to capture it again and connect with the wildlife rehab center to get more advice.


Why do birds hit your windows?

The best method for stopping it grab some cling-film and roll it as high as you can so that it’s wrinkled and then lay it over it on the exterior (not to the inner) of the glass.

Why do birds like windows?

“Birds see differently from humans,” Martyn states. ” They don’t perceive glass as something solid. For them, it might appear like you’re flying across the glass towards the opposite side. The glass also reflects the sky, the landscape or the water and it appears as if the landscape is continuing which is why they may just fly straight into it.”
