@samueltyler2 Canadian Geese are very dirty birds. Where my best friend has lived, a huge migrating area where they stop and leave their poop all over.
@Kstrong Agreed as to the fact that what they do is consume large quantities of grass and poop a lot, I call them flying poop manufacturing plants. But, they are not particularly dirty themselves. The golf courses around here hire trained dogs to chase the geese away and they put a form of netting over some lakes and ponds to prevent the birds from landing on them. They also have decoy statues of dogs around the courses.
