An adult swan eats about 4kg of aquatic vegetation every day. It reaches these underwater plants by plunging its long neck into the water, or 'upending', tail in the air. To help with the digestion of these plants in its gizzard, or second stomach, the swan swallows grit which grinds up the food.
How do swan get their food?
Swans eat aquatic vegetation, which their long necks equip them to take from the riverbed. They take the molluscs which cling to the vegetation and also eat small fish, frogs and worms. They will graze big grassy fields, and can survive quite successfully in a field of short-cropped grass.
What does a swan goose eat?
Since they are herbivores, the main source of food for a swan goose is grass, roots, leaves, and plants near lakes or any other water body. Apart from their regular food, they enjoy eating seeds and berries as well.
How do swans chew?
As we have mentioned before, unlike humans and most other mammals and animals, swans do not have teeth to chew their food. Nonetheless, a swan's bill has undergone many specialized adaptations to make it easier for them to manipulate and eat their food.
What does a mute swan eat?
The main food source of mute swans is submerged aquatic vegetation (Figure 9). They also consume small fish, insects and other small animals incidentally along with plants and when plants are sparse.
