Window Strikes and Birds Pecking at Windows
If a bird is flying at your window, it's probably a case of mistaken identity. The bird sees its own reflection and perceives the "other bird" is a competitor. The bird is attempting to drive away the "intruder" by attacking the window.
During breeding season, songbird hormone levels rise, making the birds more territorial and defensive of their territory. They attack other birds to protect their mates, food, and nesting or roosting sites. This behavior increases their chances of successfully raising a family.
What can I do?
- Decrease the reflectivity of your windows. Consider using soap or other water-soluable solutions on the outside of your window. Shades and other interior window covers don't change the window's reflection.
- Break up the reflection by hanging a decorative window film over the window or by using one-inch wide tape or ribbon to create vertical stripes every four inches on the outside of the window.
- Create a physical barrier: Put a screen or fine-mesh netting over the window.
