The City of Ottawa blames geese for E. coli despite routinely dumping raw sewage into the Ottawa river due to linked storm and sanitary sewers. The beaches are closed after significant rain storms.
Parents (ie. voters) see the poop, they don't see the sewage dumping.
In general, it is like people blaming cats for decimating birds population (in SF parks for example) while people happily gather wild birds' eggs (seems it is popular in Asian cuisine as i saw only Asians doing it).
Note: cats actually protect birds population from rats (who is actually able to eat eggs) and by occasionally eating an ill bird (we've been through this with wolves). Unfortunately cats can't protect birds from people.
