Zusammenfassung:PROBLEM TO BE SOLVED: To provide a bird-repelling system emitting stimuli to which birds are hardly acclimated and also easy to install without affecting the peaceful environment for neighbouring residents and passersby. SOLUTION: The bird-repelling system includes multiple light emitters 1 turned to directions differing from each other. In this system, each of the light emitters 1 is equipped with a light-turning-on/off control unit 2 functioning to vary in an irregularly periodical way two or more parameters among lighting time, lighting-out time, emission wavelength and mutual turning-on/off timing, wherein the control unit 2 is constituted of an exclusive subcontrol unit 3 for each of the light emitters 1.
