A system and method for driving geese away from an area employs predetermined random illuminations of particular wavelength light directed in a fashion that repels geese while avoiding annoying humans. Embodiments include systems associated with golf course flags and other structures and animal decoys that hide undesired aesthetic appearances of prior art industrial lighting elements. Other embodiments employ adjustable/movable mirror elements used in conjunction with systems powered by solar energy panels positioned below the light source, which can be adjusted in terms of direction, shielding, color, duration, wavelength and pulsation, providing a variety of random patterns so as to avoid habituation by geese.
