Bird B Gone Solar Bird Chase Super Sonic™ is an outdoor sound device powered by solar energy and is used to scare birds away. Ideal for use in large open spaces where there is no access to a power source. It clears open areas of nuisance birds by broadcasting 22 distress and predator calls every 10 min. Solar panels charge and store energy to keep the system operating during inclement weather. A built-in light sensor automatically powers down the deterrent when the sun goes down. Install the product in a location that is easily accessible in order to turn on the unit every morning.
