According to a study conducted in 2014, approximately 1 billion birds die in the U.S. each year due to collisions with windows and glass surfaces.
The behavior of birds often surprises observers, even though they have been a subject of scientific research for a long time. Notably, one of their peculiar “habits” is to dive headfirst into, peck at, and damage completely inanimate objects like windows, car windshields, and rearview mirrors…

According to a study conducted in 2014, approximately 1 billion birds die in the U.S. each year due to collisions with windows and glass surfaces.
Scientists explain that most bird species cannot distinguish their own reflections in mirrors. For them, the first instinct upon seeing this image is to dive in to attack to protect their nests and chicks.
This phenomenon occurs most frequently in the spring when territorial behavior in birds is at its peak. “Birds are clearly not the Einsteins of the animal kingdom,” said Rita McMahon, director of the Wild Bird Fund in New York City.
“Animals need a certain level of awareness to pass the mirror test, and birds typically do not achieve this.”
Windows and glass surfaces may also reflect images of the sky, grass, etc., making it hard for birds to differentiate. At night, migratory birds often collide with glass surfaces due to seeing lights.

To date, science has not yet explained why light diverts nocturnal migratory birds from their original paths, especially under low ceilings or foggy conditions.
In illuminated areas, they tend to fly erratically, sometimes colliding with each other or with illuminated structures.
Experts suggest that making a few small changes can prevent windows and glass surfaces from becoming a “target” for birds. One solution is to use non-reflective materials for the exterior of windows and glass.
Additionally, installing sun shades or outdoor awnings on windows can help reduce sunlight reflections. Blocking window access with greenery and hanging baskets is also an effective solution.
