Open spaces like roofs and courtyards are often difficult to protect using traditional bird control devices. Bird Barrier’s Eagle Eye is an optical bird repellent that harmlessly deters birds from unwanted areas by making use of light beams reflected from direct sunlight. The reflective pyramid rotates sending the beams around in a menacing pattern disorienting birds in flight by significantly limiting their vision. This causes the birds to deviate and fly to another destination. Bird Barrier offers motorized and wind-driven kits.
