Goose damage 

The problem with geese is that they eat grass, corn, wheat and the like. Goose damage can be prevented by inhibiting access to the vegetation. 

 

Based on this principle CABWIM has developed a patended approach and built a prototype on solar energy on a 2 ha meadow to mechanically and continuously threaten geese that try to fly into this area. If landed then the apparatus really provides a negative physical experience, but pain or killing is not involved.
