Abstract: The disclosure presents systems, methods and computer program products relating to a wind farm. The presence of flying animals, such as birds, bats, and insects may be determined. Deterrence elements such as acoustic and/or visual deterrence elements may be activated in an attempt to deter animals whose presence was determined, and/or independently of a determination of animal presence. The rotation of the blades of one or more wind turbines may be slowed down and/or halted if collision is probable, in order to prevent flying animal casualties. Energy from deterrence elements may produce a predetermined tempo-spatial pattern of lights and/or sounds.

Abstract: In a system for deterring intruding animals in a surveillance space or surveillance area, one or more detectors monitor the surveillance space or area for the presence of intruding animals. Each detector generates a signal that is analyzed by a processor in order to determine whether any intruding animals are located in the space under surveillance. When an intruding animal is detected, the processor determines an azimuth and elevation of the intruding animal. The processor then aims deterrence devices at the intruding animal and activates the aimed deterrence devices.
