As a species, Canada Geese are migratory, but when humans feed them in the fall, they tend to stay where they can get free meals with no work. Then, because in this species migration is not instinctive but must be learned from parents, the skill is lost in one generation, and all the offspring are doomed to freeloading. The result is beautiful wild birds becoming unwanted pests, overpopulating suburban catchment ponds and spoiling lawns with their droppings. All because some folks can't accept that wild critters are not pets.
Dealing with them is difficult, because legally they are still protected by international treaty despite no longer being migratory, or even truly wild. And, of course, some folks will object to any means of control at all. These birds could be feeding the hungry. Instead, they are killed by turtles and dogs, and hit by cars as they waddle around residential neighborhoods. Sad.
