Dear Beam: Canada geese are nuisances in many places in US, but are still protected. Smithsonian magazine had article about company with very large lawn surrounding a pond getting specially trained Border Collie to keep herding them off the grass into the pond. Since there was nothing in the pond they wanted, they stopped oming.
I also marvel that Dulles Airport has a large pond with many geese crossing landing strips to get to the pond. One goose in jet intake = one horrible crash. But the bleeding hearts won't allow the geese to be harassed in any way.
