Preventing Bird Collisions with Windows: Tips and Tricks

Hello readers,

As bird lovers, we often enjoy their presence around us; however, it can be heart-breaking to see them crashing into our windows. While many bird species are endangered, collisions with buildings remain the most significant anthropogenic cause of bird fatalities. It’s frustrating for both birds and humans as the windows act like mirrors and reflect the surrounding environment, which confuses the birds.

The good news is that there are ways to prevent birds from flying into windows, and in this article, we will be sharing 12 steps to help you prevent or reduce bird collisions.

Step-by-step guide to stop birds from flying into windows

Step 1: Understand the problem

To solve this problem, we first need to understand it. When we are unaware of what’s causing birds to crash into our windows, we can’t choose the right solution. So, the first step is to learn why birds fly into windows and the species of birds involved. Several factors contribute to the collisions, such as weather, the bird’s behavior, the type of window, and the surrounding habitat.

Step 2: Install decals and bird-friendly stickers

Decals and stickers are a simple and cheap way of preventing bird accidents. Attach them to your windows at spaced intervals to break up the reflection of the surrounding environment. They also act as a visual warning to birds that there’s an obstacle ahead.

Step 3: Create an exterior visual barrier

Birds develop a preference for familiar habitats and can recognize objects in their environment. By creating an exterior visual obstruction, you create a physical blockade to birds’ sight and a warning to stay clear. Methods include installing netting, screens, or film on the outside of the window.

Step 4: Consider window tinting

Tinting your windows reduces transparency, which makes it harder for birds to see through the glass. The tint also minimizes the reflection and glare that birds confuse.

Step 5: Install bird feeders or birdbaths away from windows

Birds are natural snackers, and installing bird feeders away from windows makes them less likely to crash into them. Additionally, adding water fountains and baths help birds cool off and hydrate without approaching reflective surfaces.

Step 6: Move houseplants away from windows

Houseplants that have large leaves or are close to reflective windows can create confusion for birds, making it difficult to spot the obstruction. Moving the plant further away from your window creates a buffer zone and helps prevent accidents.

Step 7: Use external shading devices

In the warm months, external shading devices like sun-shades and retractable awnings prevent glare and reduce reflection from your home’s exterior.

Step 8: Close blinds and curtains during the day

While opening the blinds or curtains to let natural light in is admirable, it can confuse birds, making it harder to spot the window’s obstruction. Keeping curtains or blinds shut until late afternoon reduces the glare and reflection of the window, making it less dangerous to birds.

Step 9: Install insect screens

Installed screens break up patterns and reduce the reflection of our windows, making it easier for birds to spot the obstruction.

Step 10: DIY bird scare tactics

You can create DIY scare tactics such as dangling beads, CDs, or shiny strings outside the window. They create motion, which scares birds and helps reduce the frequency of collisions.

Step 11: Install different types of windows

Installing different types of windows such as stained glass or frosted glass can significantly reduce window collisions.

Step 12: Use UV-reflective glass

UV-reflective glass is a relatively new technological solution to bird strikes. The glass reflects ultraviolet light, which birds can detect.

Tips and Tricks to Prevent Birds from Flying into Windows

Tips 1: Keep your windows clean

A dirty window can potentially increase the reflection and glare, making it more difficult for birds to identify it as an obstacle.

Tips 2: Install internal lighting

By installing internal lighting, birds aren’t drawn towards dysfuctional light sources and become less likely to approach windows.

Tips 3: Remove indoor plants

Trailing indoor plants that require sunlight can trail off windows. Removing those plants from the room sends out less visual information and reduces the frequency of window strikes.

Tips 4: Use blinders or curtains on sloping windows

Inclined paned windows tend to act as mirrors, making it hard for birds to distinguish them and avoid collision. Installing blinders or curtains on these types of windows can help prevent accidents.

Tips 5: Make sure bird feeders and baths are the right distance from windows

Bird feeders or baths placed too near to windows encourage birds to fly into them. Placing them at the right distance decreases their chances of striking a window.

Tips 6: Place bird feeders in the line of sight of an indoor person

Having a locator inside the house furthers the chance of you spotting the birds and getting the opportunity to take action.

Tips 7: Create a natural screen

Creating a natural screen of trees and plants between your windows and the outdoor environment minimizes the reflection on the window, making it less noticeable for birds.

Tips 8: Turn off lights at night

Birds are nocturnal creatures and are often drawn into bright light bleeding through windows. Ensure that lights facing windows are turned off when you’re not using them.

Tips 9: Reduce reflections from other objects

It’s not solely the windows that serve as reflections. Any object with a shiny or reflective surface could create confusion for birds flying into a window. Reducing reflection from surfaces such as shiny objects and car mirrors significantly reduces window strikes.

Tips 10: Participate in bird conservation programs

Participating in bird conservation programs could help reduce glass-related accidents, among other bird hazards.

In conclusion, several techniques can prevent birds from flying into windows. It’s our responsibility to ensure that the birds we love and appreciate aren’t at risk, and we can do this by making slight adjustments to our homes and habits. By simply following the steps and tips outlined in this article, we can help reduce bird collisions and save the lives of our feathered friends.

Advantages and Disadvantages of How to Stop Birds Flying into Windows


1. Saving bird lives: By implementing methods to deter birds from flying into windows, we can save countless bird lives. Birds often mistake windows for open spaces and fly into them, causing severe injuries or death.

3. Lower energy costs: Implementing methods to prevent birds from flying into windows can also lower energy costs. As birds can mistake windows for open spaces, they may attempt to fly through the glass, causing drafts and an increase in energy consumption.

4. Reduced noise pollution: Birds flying into windows can cause a loud and unpleasant noise. By deterring birds from entering these areas, we can reduce noise pollution significantly.

5. Aesthetic appeal: Implementing methods to protect birds can also add to the aesthetic appeal of a building. Companies can utilize visual markers and other methods to deter birds without affecting the appearance of the building.

6. Educational opportunity: Educating the public about the importance of bird conservation and methods to prevent bird-window collisions can promote community engagement and do good in the environment.

7. Reduced likelihood of window strikes: Implementing methods to deter birds can help reduce the likelihood of window strikes, which can cause harm to both birds and humans alike.

8. Long-term savings: Investing in bird deterrence methods can help buildings save money in the long term by reducing damage to windows and reducing energy consumption.

9. Contributing to bird conservation: By protecting birds from window collisions, we are helping to contribute to bird conservation efforts and protecting these delicate creatures.

10. Compliance: Many cities and buildings have regulations or standards for bird deterrence methods. By complying with these regulations, companies can avoid legal issues and fines.


1. Cost: Depending on the method chosen, implementing bird deterrence methods can be costly.
