Diet. Snow Geese feed almost exclusively on plant material. During the breeding season, they eat many seeds, leaves, and roots of aquatic vegetation. The very young birds feed on invertebrates. Berries become more important in the fall. In winter, waste grain from agricultural fields has become a primary food source.
Feed Canada geese away from walking paths. Most people do not like their poop and they are exposed to dangers from dogs, bikes, racing kids, skateboards, etc. Feed them on the grass close to the water but do not throw the cracked corn or bread into the water. They have a tendency to sink to the bottom of the pond.In the heat of summer, the accumulated food can become toxic, causing a condition known as botulism, which has been known to kill pond animals.anada geese will not remain in an area because you feed them and migrating geese migrate, duh! Certain news articles and wildlife agencies advise us not to feed Canada geese. They claim that we will do them more harm than good.
