Did You Know?

1. Can birds see glass? Yes, but not always. Some birds cannot see glass and may accidentally collide with it, while others can perceive it.
2. A type of bird called the African Grey Parrot has been scientifically proven to possess the ability to recognize itself in a mirror, implying that it can see its reflection and understand it is not another bird.
3. Many bird species have an additional eyelid called the “nictitating membrane.” This transparent membrane serves as protection while still allowing birds to see their surroundings, which is especially useful when flying through densely forested areas.
4. Pigeons have a remarkable ability to navigate, even in unfamiliar locations. Researchers believe that they use visual landmarks, such as the position of the sun and the angles of buildings, as well as their incredible memory to find their way home.
5. Falcons, known for their exceptional eyesight, have an additional adaptation called “foveae.” These are specialized areas of the retina that contain a high concentration of photoreceptor cells, allowing them to spot prey from great distances and while in high-speed flight.


Window Decals And Screens

Bird collisions with glass windows are a concerning issue that affects millions of birds each year. However, there are various measures that can be taken to prevent these unfortunate accidents.

One effective method is the installation of window decals or screens. These products create a visual barrier that birds can recognize, reducing the likelihood of collisions.

  • Window decals come in a range of designs, such as silhouettes of birds of prey or patterns that birds can easily spot and avoid.
  • Screens, on the other hand, create a physical barrier that prevents birds from flying directly into the glass.

With these simple preventative measures, we can minimize the number of bird collisions and ensure their safety.

Soap Or Tempera Paint Markings

Another way to prevent bird collisions is by marking windows with soap or tempera paint. This method involves creating grid patterns or creative artwork on the windows, which help birds distinguish between a solid barrier and an open path. The markings break up the reflective surface of the glass, making it more visible to birds and reducing the chances of them crashing into it.

By using soap or tempera paint, we can transform our windows into bird-friendly surfaces and protect these magnificent creatures from unnecessary harm.

Mosquito screens are designed with small openings that allow air circulation while ensuring the safety of birds. By incorporating mosquito screens into our windows, we can create a safe environment for birds without compromising the comfort and functionality of our living spaces.

Netting For Bouncing Birds Off

Netting positioned at least 3 inches away from the glass serves as a protective barrier and helps bounce birds off. By creating a cushioning effect upon impact, the netting absorbs the force of the collision and redirects the birds away from the window. This approach reduces the likelihood of injury and gives birds a chance to avoid crashing into the glass. The proper installation of netting is crucial to ensure its effectiveness in preventing bird collisions and maintaining a safe living environment for birds.

  • Netting should be positioned at least 3 inches away from the glass.

External Shutters

Installing external shutters and keeping them closed when the windows are not in use is an effective way to prevent bird collisions. These shutters act as a solid barrier, making it evident to birds that there is an obstruction in their flight path. By closing the shutters, we create a physical barrier that ensures the safety of birds and minimizes the risk of collisions. External shutters are a practical and visually pleasing solution that adds value to buildings while protecting bird populations.

External Sun Shades Or Awnings

External sun shades or awnings prevent bird collisions by blocking sunlight reflection that can attract birds and mislead them into believing that the window is an open path. By installing these shades or awnings, we minimize reflective glare that confuses birds and reduces their ability to perceive the presence of the glass. This approach not only protects birds but also provides shade and temperature regulation benefits for buildings, contributing to a more comfortable living environment.

Windows With Screens

A proactive measure during construction or window replacement is to choose windows with screens on the entire outside surface. This design ensures that birds can easily recognize the presence of a barrier and avoid collisions. By incorporating screens into windows, we create a bird-friendly environment from the initial stages of building development, minimizing the risk of bird collisions and promoting their safety.

Avoiding Bright Windows

To prevent bird collisions, it is essential to avoid having bright windows on the opposite wall that may create an illusion of an open path to the sky. Birds can be easily misled by reflections on windows, mistaking them for the sky or a clear path. By ensuring that bright windows are avoided, we eliminate this confusion and minimize the chances of collisions. This simple yet crucial measure significantly contributes to bird safety around buildings.

“Lights Out” Initiative

Participating in the “Lights Out” initiative is an important step in reducing artificial light that can draw migrating birds off course. Many bird species migrate at night and use celestial cues for navigation. Artificial lights, such as those from buildings, can disrupt their natural navigation patterns, leading to collisions with windows. By turning off unnecessary lights at night, especially during migration seasons, we can provide a safer passage for birds and contribute to their conservation efforts.

The prevention of bird collisions with glass is a pressing matter that requires our attention and proactive measures. Here are some tips to create a safer environment for birds:

  • Use window decals or screens to make windows more visible to birds.
  • Mark windows with soap or tempera paint to create a barrier that birds can see.
  • Utilize objects on the outside surface of windows, such as dot patterns with tape, zen curtains, mosquito screens, or netting, to break up reflections.
  • Consider using one-way transparent film, external shutters, or external sun shades or awnings to reduce the reflectiveness of windows.
  • Install windows with screens or interior vertical blinds to create a physical barrier.

Being mindful of bright windows and participating in initiatives like “Lights Out” can make a substantial difference in protecting bird populations. Let’s take action today to ensure that birds can safely navigate their surroundings without the threat of colliding with glass.

FAQ

What do birds see when they see glass?

Birds perceive glass as a deceptive obstacle. Instead of seeing it as a solid barrier, they may overlook its presence and perceive it as an extension of their environment. Glass can either appear as a pathway to the other side or a continuation of the surrounding landscape, leading birds to mistakenly fly into the glass with unintended consequences.

Can birds see their reflection in glass?

Birds, with their keen eyesight, are indeed able to see their reflections in glass. However, the image they perceive is often mistaken for an intruder rather than a reflection of themselves. The confusion arises because birds interpret their own reflection as a rival encroaching upon their territory. This prompts them to engage in aggressive behavior, such as pecking or striking the glass, as a means to defend their space.

Can birds see me through windows?

Birds, unfortunately, cannot see through windows, which often leads to unfortunate collisions. The human-made concept of windows is unfamiliar to them, as they have not evolved to recognize them as barriers. The transparent and reflective qualities of windows create a deceptive illusion for birds, making them unaware of the solid obstacle in front of them. Consequently, these collisions serve as a reminder of the challenges wild animals face when interacting with human structures.

What do windows look like to birds?

To birds, windows can be deceptively misleading. Rather than appearing as solid barriers, they often reflect the surrounding nature, creating an alluring illusion of open spaces. Whether mirroring vibrant foliage or a boundless sky, windows appear as tempting destinations for flight. Tragically, the staggering quantity of windows exacerbates the problem, resulting in an alarming toll on bird populations. Studies indicate that an estimated one billion birds meet their untimely demise from window strikes annually in the United States alone, indicating the dire consequence of this deceptive relationship between birds and windows.
