March Goslings and geese eating their natural food

The goslings and geese are enjoying grazing naturally on grass and plants on the riverbank in March Cambridgeshire. No bread or petfood - just the natural plants. Geese graze on grass from which they get their nutrients. They are not like ducks and other waterfowl. They do not eat in the water but graze the grass on the riverbanks. This is especially the case in summer when there is plenty of grass and plants available. No need for any extra feed. These geese are living wild and should be self-sufficient, not relying on humans for food. They have to look after themselves and their goslings against predators. .
