Abstract: A pest deterrent apparatus that uses a rotating mirror to paint a beam of sunlight onto a predetermined area of interest. The beam of sunlight being reflected onto the area of interest deters birds and other pests from landing or gathering in the area of interest. A global navigation satellite system (GNSS) device and a compass are used to determine the position of the sun with respect to the mirror. A pattern generator computes the movement of the mirror required to paint the predetermined area of interest with the beam of sunlight. The movement of the mirror is adjusted as the sun moves across the sky such that the predetermined area of interest continues to be covered with the beam of sunlight as the sun moves across the sky.
