Why Birds Collide With Windows
Birds often fly into windows because they see reflections of the sky or trees. These reflections make the glass look like open space or habitat. Birds cannot tell the difference between real space and reflections. They try to fly through, causing collisions.
Transparent windows also confuse birds. They may see plants or sky through the glass and think it is safe to fly. This happens especially with clear glass that shows the inside of a room or plants behind the window.
Bright lights inside buildings can attract birds at night. Birds may get disoriented and fly into windows near these lights. This happens more during migration seasons when birds travel at night.
