Up to one billion birds die each year by striking windows. Bird eyes do not interperet windows as solid objects. At Utah State, hundreds of birds die each year in bird strikes. One of the buildings that is responsible for a large portion of bird strikes is the Chase Fine Arts building. Fruit trees in front of the Chase Fine Arts windows cause a reflection which confuse birds A redution in window reflectivity greatly reduces bird strike problems.
