We usually see birds flying into windows in summers without any provocation. Window glasses reflect the open outside world, which appears a clear path of flight according to the bird’s point of view and encourages them to explore the wide sky, trees and flowers reflected on the windowpane. This misconception prompts the birds to collide with the windowpane, and procure fatal injuries. According to a survey, around one billion birds are killed annually only in North America from colliding with large windowpanes.
