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.
Grass and pond plants are the best food for goslings. WHEN NOT TO FEED CANADA GEESE: If your park has a NO FEEDING policy (indicated by signs posted throughout the park), for the sake of the geese, please DO NOT FEED THE GEESE! To me, these are indications of intolerance toward Canada geese.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.
