Helping Prevent Window Strikes

Spring and Fall are prime seasons for Wildlife Migration.  During these seasons, the Wildlife Hospital always sees a steep increase in birds admitted for window strike treatment . This uptick highlights the dangers migrating birds face as they navigate urban landscapes.

Why Are Birds Striking Windows? 

During migration, birds often travel at night and may be disoriented by city lights and reflective surfaces. Glass windows and railings, which can appear invisible to birds, present a deadly hazard. With their large windows and glass balcony railings, high-rise buildings are especially dangerous for migrating birds.

The Hidden Dangers 

Window collisions are a leading cause of death for migratory and resident birds across the world. The stark reality is that these bird-glass collisions result in the death of approximately 25 million birds annually in Canada, a statistic reported by Global Bird Rescue. 

Birds that have impacted a window often suffer from concussions, internal injuries, eye injuries, and fractured bones. Even if a bird seems to recover from an initial window strike, injuries can develop or worsen up to 48 hours later. This delayed effect makes immediate care from a trained wildlife rehabilitator critical for the survival of these birds. 

How You Can Make a Difference 

There are several proactive measures you can take to help reduce window strikes and safeguard migrating birds: 

• Close Your Blinds: This simple action helps reduce reflections during day and night and makes glass windows less confusing for birds.
• Use Window Decals: Applying decals or patterns to your windows can make them more visible to birds and prevent collisions. When using window decals, it’s important to apply the pattern across the entire glass. Spaces in between stickers should be no greater than 5 cm/2 inches and each sticker at least 5 mm wide. They should be applied to the outside of the window. Find more information on window decals here.
• Get Creative with Tempera Paint: Mark the outside of the window with tempera paint, which is affordable and long lasting. You can use a grid pattern of 2 inches by 2 inches or get creative and create artwork covering the whole surface of your window. 
• Turn Off Lights at Night: Bright lights can attract birds. By dimming or turning off unnecessary lights, you can help birds navigate more safely. It’s still good to take additional precautions against window collisions using any of the above methods

What to Do if a Bird Strikes Your Window
