The headline says it all: "New Jersey declares war on Canada Geese." The saga of the Canada Goose (Branta canadensis) is an interesting one. The species was once quite rare, but now populations have expanded to the point where the geese are now unwelcome guests in many parts of the U.S. In large quantities, their waste can pollute bodies of water and is an unsightly mess in grassy areas. An additional problem is that some geese have altered their migratory patterns to overwinter in cities, becoming a year-round issue.
Canada Geese have of course been introduced into Europe and the U.K., where they are causing similar problems and winning similar affections from people. As a response to unwanted geese, various inventions have sprung up to combat local goose "infestations." My favorite one is the RoboGoose (the video is a must-see!).
