Understanding the Problem
Bird-window collisions are a common problem that can lead to injury or death for birds. Birds often don’t see windows as a solid barrier because they are transparent or reflect the surrounding environment. This misunderstanding can result in birds flying into windows at high speeds, causing injuries or fatalities. Additionally, birds might be attracted to windows due to what they perceive as shelter, food, or potential mates inside.

One primary reason birds hit windows is due to reflection issues. When birds look at windows, they often see the reflection of the sky, trees, and other natural surroundings, rather than a solid pane of glass. This leads them to believe they are following a clear flight path, which unfortunately results in a collision with the window. Reflection issues can be especially problematic during migration and breeding seasons when birds are more active and might be less cautious about where they are flying.
Migration and Breeding Season
Migration and breeding seasons are critical times of increased activity for birds. During these periods, birds are focused on finding food, establishing territories, and searching for mates. As a result, they may be more likely to have window collisions due the increased movement and distractions. Migration in particular can exacerbate the problem, as birds might be unfamiliar with a certain area and its windows. Addressing the bird-window collision problem during these seasons can be a key step in protecting our feathered friends.
Window Decals and Stickers
One effective method to deter birds from hitting windows is using window decals or stickers. Placing them on the glass at 2-inch intervals can help protect even the smallest birds like hummingbirds and kinglets. These decorative decals can create visual barriers that prevent birds from flying into windows, reducing the risk of injury or death.
Installing Window Screens
Window screens are another effective prevention strategy. By installing screens on the exterior of your windows, you create a physical barrier that prevents birds from striking the glass. Aside from their protective function, screens can also help with ventilation and keeping insects out of your home.
Using Window Film
Applying window film to your glass surfaces is another method to minimize bird strikes. One-way transparent film allows you to see outside while obscuring the view from outside. This reduces the window’s reflectivity and transparency, making it less appealing for birds to fly towards.
Applying Tape or Paint
Using tape or tempera paint on the exterior of your windows can also deter birds. Vertical white tape strips spaced 4 inches apart or horizontal black strips spaced 1 inch apart help create a visual barrier. Alternatively, you can draw a pattern on the glass with a paint marker or soap to reduce the chances of collisions.
Window Blinds and External Shutters
Lastly, window blinds and external shutters can serve as an effective prevention technique. Blinds should be tilted halfway and in a way that reduces glare, while external shutters can be closed when windows are not in use to avoid attracting birds. Both measures can help reduce reflection and transparency, further reducing the risk of bird collisions with your windows.
Strategic Bird Feeder and Plant Placement
Interrupting Birds’ Flight Path
Placing bird feeders and plants strategically can help prevent birds from colliding with your windows. One way to interrupt birds’ flight paths is to use plants around your window area. Create an environment that encourages birds to slow down and navigate around the vegetation instead of flying straight towards the window.
Another method is to apply window decals or other visual deterrents on the window surface, making it more identifiable as an obstacle for birds.
Creating Safe Distances
To minimize the risk of window collisions, it’s crucial to find the ideal distance between your bird feeder or plants and the window. According to Marc Parnell, author of The Birding Pro’s Field Guides, a bird feeder should be placed at a distance of at least 25 feet from the window. This distance allows birds enough time to adjust their flight pattern, reducing the chances of a fatal collision.
However, another source suggests that feeders can be placed within 3 feet of windows Birds and Blooms. At this close distance, birds are less likely to gain enough momentum to cause harm during collisions. Consider the layout of your space and strike a balance in distance according to your specific needs.
Predators, such as cats and other animals, can pose a threat to birds visiting your feeders and plants. All About Birds advises that bird feeders should be placed in safe locations, away from areas where predators can easily hide and ambush unsuspecting birds.
Consider the following when managing predators in your bird-friendly space:
- Install bird feeders high enough to deter ground-dwelling predators.
- Keep bushes and other hiding places away from the feeder area.
- Use devices such as baffles or specialized feeder designs to prevent larger animals from accessing the bird food.
By applying these measures to your bird feeder and plant placement, you can reduce the risk of birds hitting windows, create a safer environment for them, and better enjoy their presence in your space.
Additional Deterrents and Solutions
In this section, we will explore various deterrents and solutions to help prevent birds from hitting windows, such as Acopian Bird Savers, window netting, wind chimes, and scare devices.
Acopian Bird Savers
Acopian Bird Savers, also known as “zen curtains,” are an effective and eco-friendly solution that help to prevent bird collisions. These are essentially strings of paracord hanging vertically outside the window, spaced about 4 inches apart. The cords act as a visual barrier, alerting birds to the presence of the window and preventing them from flying into it. Installation is simple and can be a DIY project or done professionally. Acopian Bird Savers come in various colors to match your home’s aesthetic and require little maintenance.
Window netting is another effective solution to prevent bird-window collisions. Made of lightweight and durable mesh material, the netting covers the exterior of the window, creating a barrier between the birds and the glass. Netting can be easily installed using hooks or brackets, and it is removable for cleaning purposes. This inconspicuous method not only protects birds but also reduces window glare and maintains your view from inside.
Wind Chimes and Scare Devices
Incorporating wind chimes and scare devices can be helpful in deterring birds from approaching windows. Wind chimes produce sound that can startle or distract birds, preventing them from flying towards the window. Place the chimes near windows where bird collisions are frequent for optimal effectiveness.
Scare devices, such as reflective tapes, predator decoys, and holographic repellers, can also be used to deter birds. These devices mimic the presence of a bird’s natural predator or create visual disturbances, which can discourage birds from coming near windows. When using these methods, it’s essential to change the location of the devices regularly to maintain their effectiveness, as birds can become accustomed to them over time.
Helping Collision Victims
Identifying Injured Birds
When you encounter a bird that has collided with a window, it’s important to first examine it for any external injuries. Check if both wings are properly held, with neither dangling, and if the eyes appear normal. If the bird can perch on a branch unassisted, it’s best to leave it to recover on its own.
Providing Safe Temporary Shelter
If the bird is unable to perch or is in an unsafe area with potential predators, you should provide temporary shelter for the injured bird. A shoebox or a paper bag can be used to create a safe space for the bird to rest. Ensure that the container is large enough for the bird to spread its wings, and line the bottom with newspapers or a clean rag to create a comfortable surface.
- Shoebox: Make sure it’s clean and free of debris. Poke small air holes in the lid.
- Paper Bag: Choose one of appropriate size and ensure it’s clean and free of debris.
Place the container in a quiet and dark location to help reduce the bird’s stress and enable a smoother recovery.
Contacting Wildlife Rehabilitators
In some cases, the bird may require the assistance of a professional wildlife rehabilitator to ensure proper care and treatment. If the bird appears to be in pain or is exhibiting other signs of serious injury, such as difficulty breathing or severe bleeding, seek help immediately.
To contact a wildlife rehabilitator, search for local organizations or individuals specializing in bird care. Keep the bird in the temporary shelter while awaiting further instructions, and provide any information they may need to evaluate the bird’s condition and determine the best course of action.
By knowing how to identify and assist window collision victims, you can play a vital role in protecting birds and reducing the impact of birds hitting windows.
Reducing Light Pollution
Turning Off Lights at Night
One effective method to prevent bird-window collisions is to reduce light pollution. By turning off unnecessary lights at night, particularly during migration seasons (from mid-March through early June and late August through mid-November), you can help protect birds as they navigate through the dark sky. Additionally, this conservation measure saves energy and reduces your electricity bill.
Installing External Sun Shades
Apart from turning off lights, installing external sun shades can help block light pollution and prevent bird deaths caused by window strikes. External sun shades, including window films and roller blinds, break up reflections on the glass and disrupt the false scene that birds perceive as a safe passage. As a result, birds become aware of the obstacle and avoid flying into the window.
Awnings are another excellent solution for reducing light pollution and preventing birds from hitting windows. By providing shade and limiting reflections on the glass, awnings not only protect birds but also help you maintain a comfortable indoor temperature. Moreover, they come in various materials, styles, and colors, making it easy to find a suitable option for your home.
Remember that these measures – turning off lights at night, installing external sun shades, and using awnings – are essential for reducing light pollution and protecting birds from window collisions. By implementing these best practices, you contribute to a safer environment for our feathered friends.
Design Considerations for Windows
Choosing Bird-Friendly Designs
Considering bird-friendly designs is essential for residential and low-rise buildings, as they can minimize the risk of bird collisions. The Audubon Center suggests using window decals but placing them no more than 2-4 inches apart for maximum effectiveness. This strategy is especially crucial during migration seasons, when a large number of migrating birds are prone to window collisions.
Another effective approach to choose a bird-friendly design is to utilize window treatments with a 2-inch by 2-inch grid pattern. This layout helps safeguard windows for smaller birds such as hummingbirds, gnatcatchers, and kinglets, effectively reducing bird strikes on the glass. Implementing such designs can be done by using window markers or tempera paints to create visually appealing and bird-safe patterns.
Implementing Bird-Friendly Building Features
Installation of external building features can also assist in protecting birds from glass window collisions. For instance, placing items such as decals, sun catchers, crystals, Mylar strips, or windsocks outside windows can break up a window’s reflection, guiding birds away from the glass surface.
Another method is attaching window screens or light nets at least 2-3 inches away from windows. When properly installed and taut, these screens create a trampoline-like effect, enabling birds to bounce off without getting injured or trapped.
All in all, incorporating bird-friendly design considerations to residential and low-rise buildings can significantly reduce avian mortality rates, protecting both the local bird population and the overall ecosystem.
