Wildlife and Habitat Conservation News reported on the threat of house windows to birds. Birds can mistake windows for openings and crash into them flying at full speed. In Canada it is believed that crashes into house windows results in 22 million bird death annually. This number does not include birds who die from crashing into commercial buildings. Most common victims of these crashes are common birds such as sparrows, robins and chickadees.
Crashes are greatly reduced by putting stickers on windows or placing objects in windows to break up the reflections. This takes away the illusion of an open space.
