Apparatus and method for deterring birds by laser

An apparatus for deterring birds from a fixed structure, comprising:

• a frame fixedly disposed on a structure;
• a laser light generator connected with the frame, including a laser light source for generating a laser light beam;
• a supply circuit for supplying the laser light source;
• driving means connected with the laser light generator, for having at least a part of the laser light generator move;
• and
• a control element for controlling the laser light source and the drivable part of the laser light generator, wherein the driving means are arranged for causing a movement to be executed of at least a drivable part of the laser light generator wherein the control element is arranged at aiming a laser beam both at the fixed structure and into the air so as to clear the fixed structure by sweeping the laser beam over the fixed structure, characterized in that the control element is further arranged in that subsequently, the laser beam is caused to move by the control element with such a high frequency along side the fixed structure that the moving laser beam is perceived as a surface that keeps the birds away from a volume defined by the surface and the area of the fixed structure.
