How to Prevent Cardinals from Attacking Your Windows

Hello friends, have you ever experienced the frustration of having a beautiful garden and watching as cardinals fly into your windows, causing damage to your home and harm to themselves? If so, you are not alone. Many people struggle with figuring out how to stop cardinals from attacking windows, but with the right knowledge and tools, it is a problem that can be solved.


Step 1: Identify the Gender

The first step in stopping cardinals from attacking windows is to determine the gender of the bird. Male cardinals are the culprits in most cases, as they often mistake the reflection in the window as a rival male. If the bird is a female, the attacking behavior is less likely to occur.

Step 2: Cover the Windows

A simple solution to stopping cardinals from attacking your windows is to cover them with a material that will eliminate the reflection. Options include window film, netting, or temporary covers made from cardboard or paper.

Step 3: Install Decals or Stickers

Another option for deterring cardinals from attacking windows is to install decals or stickers on the glass. This breaks up the reflection, reducing the chance of the bird attacking.

Step 4: Place Objects in Front of Window

Bird feeders, wind chimes, and potted plants placed in front of the window can also be effective in stopping cardinals from attacking. These objects are visual barriers that will disrupt the reflection and prevent the bird from attacking the window.

Step 5: Reduce Light Inside the House

If your windows are particularly large or numerous, reducing the amount of light inside the house can be effective in reducing reflections.

Step 6: Take Down Mirrors

Mirrors can also be a problem when it comes to stopping cardinals from attacking windows. If you have mirrors in your garden or near the windows, it is best to take them down or cover them up.

Step 7: Use Deterrent Sprays

Deterrent sprays, such as vinegar or lemon juice, can be sprayed on the outside of the window or on the window coverings to reduce reflections and prevent birds from attacking.

Step 8: Try a Bird Deterrent

Specialty bird deterrents, such as bird spikes or netting, can be installed around the window to prevent birds from landing in that area.

Step 9: Move Bird Feeders

If you have bird feeders near the window, consider moving them to another location. This will reduce the amount of time the birds spend in the area and lower the risk of them attacking the window.

Step 10: Use Motion-Activated Devices

Motion-activated devices, such as sprinklers or sound emitters, can be effective at deterring birds from approaching the area near the window.

Step 11: Trim Trees and Shrubs

Trimming trees and shrubs near the window can also be effective in stopping cardinals from attacking. This eliminates high perches and reduces access to the window.

Step 12: Seek Professional Help

If you have tried all of these steps and the problem persists, it may be time to seek professional help. A bird control specialist can provide further assistance in finding a solution to stop cardinals from attacking your windows.


As mentioned, male cardinals are more likely to attack windows as they often mistake the reflection for a rival male. The reflection triggers their territorial instincts, causing them to attack the window repeatedly. By covering the window, reducing the reflection, or providing visual barriers, it eliminates the trigger for the bird’s behavior.

Deterrent sprays can mask or eliminate the reflection and deter birds from landing on or near the window. Specialty bird deterrents can be installed to create a physical barrier that prevents birds from landing on or near the windows. Motion-activated devices can be used to scare birds away from the area.

Trimming trees and shrubs eliminates high perches and physical access to the window. Seeking professional help can provide you with additional strategies to deal with the issue.

Tips and Tricks

Tip 1:

Place objects in front of the window that are non-reflective, such as bird feeders, wind chimes, and plants.

Tip 2:

Use tempera paint to create abstract designs on your windows. This breaks up the reflection and reduces the chances of birds attacking.

Tip 3:

Keep your windows clean to prevent the buildup of dirt and grime, which can increase reflection and trigger bird behavior.

Tip 4:

If possible, move your bird feeders to another location, away from the windows.

Tip 5:

Use tape to create a criss-cross pattern on your windows. This can help to break up the reflection and deter birds from attacking.

Tip 6:

Try using a combination of methods to increase effectiveness. Use window film along with bird deterrents or visual barriers.

Tip 7:

Be patient. Cardinal behavior is instinctual, and it may take time for the birds to adjust to new visual cues and deterrents.

Tip 8:

Keep in mind that the cardinal’s behavior is not meant to be malicious. They are simply responding to their instincts.

Tip 9:

Take action as soon as possible. The longer the behavior persists, the greater the risk of harm to the bird and damage to your home.

Tip 10:

Remember that prevention is key. Taking steps to prevent birds from attacking windows is much easier than dealing with the aftermath.
