I work at a hospital that has several large green lawns spread around it.
Apparently, sometime in the past the hospital decided there was a geese problem and decided to erect seven plastic coyotes across the grounds.
One month ago the hospital's green turf was spotted with gaggling fiends. Then the yearly coyotes were put up. Now the lawn is geese free.
I made the following pictures to explain the plastic coyote/geese relationship.
