Diet / Feeding:

Geese feed mainly on plant material. When feeding in water, they submerge their heads and necks to reach aquatic plants, sometimes tipping forward like a dabbling duck.

Flocks of these birds often feed on leftover cultivated grains in fields, especially during migration or in winter.

Ducks and geese generally feed on larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails, and crabs.
