This invention relates to a method and apparatus for averting water fowl settlements using a humane, non-lethal, optionally solar and rechargeable battery operated microcontroller controlled by preset code, a multi-patterned and changing light generating apparatus, with at least 500 nm to 570 nm visible and 300-399 nm ultraviolet spectrum LED lights, activated by means for sensing ambient light levels to determine activation periods and resting periods for retraining water fowl to relocate settlements to an alternate location by disrupting their dark-adapted night vision. The apparatus may be in the form of a floating buoy or a land or other structural surface mountable device and includes means to prevent perching thereon.
