Ducks are a part of the Anatidae family, which includes swans and geese, and there are 23 common members of this family in Australia. Ducks can be dabblers, filter-feeders, or diving ducks, and they are all birds of the wetlands with webbed feet and flattened bills. The Australian duck industry produces over 8 million ducks annually, and the demand for duck meat is increasing. Ducks' diets change as they mature, and they require a balanced diet to remain healthy and breed successfully. So, what do Australian ducks eat?

What You'll Learn
Australian Wood Duck diet
The Australian Wood Duck, also known as the Maned Duck or Maned Goose, is a dabbling duck found throughout much of Australia. It has a wide geographic range and can be observed in a variety of environments, including grasslands, open woodlands, wetlands, flooded pastures, and coastal areas. They are highly social and may form flocks consisting of 2,000 or more individuals.
The Australian Wood Duck is an agricultural pest in some regions of Australia due to its preference for foraging on land, particularly in grasslands and crops. They mostly feed by grazing in flocks and have been known to damage crops and pastures. Their diet consists primarily of grasses, grains, clover and other herbs. They also occasionally eat insects.
This duck species is rarely seen on open water, preferring to dabble in shallow water to forage. They are commonly found near permanent water sources such as dams, ponds, pools, and irrigated grass areas. They benefit from the abundance of freshwater sources provided by agriculture and urban developments.
The Australian Wood Duck has a medium-sized goose-like appearance, with a dark brown head, a pale grey body, and two black stripes along the back. The male, or drake, has a small dark mane, a speckled brown-grey breast, and a black underbelly. The female, or hen, has a paler head with two white stripes above and below the eye, a speckled breast, and a white underbelly.

Black Swan diet
Black Swans, iconic in Australia, feed on aquatic vegetation in shallow water. They also eat grasses on land and the occasional bug or insect.
In general, swans eat plant matter but can also consume small aquatic animals like fish, worms, and frogs. They should never be fed processed meats. Swans also eat vegetables, and specialist swan and duck food pellets that float are a great choice. Swans have been seen feeding on leftover potatoes in fields, but these should be unseasoned and cut into small pieces.
During the summer, swans' diets consist mainly of aquatic vegetation, eaten while swimming, such as underwater plants and algae. They also eat grasses found along the banks. In the winter, they eat small insects and cultivated grains in open fields.
When feeding swans, it is best to stay as close to their natural diet as possible. Bread is not good for swans, as their digestive system is not designed to metabolize refined flour, preservatives, yeast, or refined sugar. Bread displaces the natural foods swans should be eating and is very high in protein compared to their natural diet. If swans eat too much bread, they become weak and breed unhealthy young.

Green Pygmy-Goose diet
The green pygmy goose, or Nettapus pulchellus, is a small perching duck that breeds in southern New Guinea and northern Australia. It is one of the smallest species of duck, ranging from 30 to 36 cm in length, with a wingspan of 48 to 60 cm. These ducks inhabit well-vegetated lowland lagoons and other permanent fresh waters, particularly those with water lilies.
The diet of the green pygmy goose is largely vegetarian, consisting of aquatic vegetation found in shallow waters. They are particularly fond of water lilies and other freshwater plants. In addition to vegetation, green pygmy geese may also include small insects in their diet, such as flies or mosquitoes that are attracted to the watery habitats they frequent.
Like other ducks, the green pygmy goose's bill is adapted for feeding in water. It has grooves called lamellae that help to grip vegetation and filter out water. This adaptation allows them to efficiently forage for food in their aquatic environment.
In comparison to other Australian ducks, the green pygmy goose is less likely to be found foraging on land or in more urban environments. They prefer to remain in their freshwater habitats, where they can dabble for food and socialise with their flock.
The diet of the green pygmy goose may vary slightly depending on the specific location and availability of food sources. However, overall, they primarily rely on aquatic vegetation and small insects that are abundant in their wetland habitats.

Magpie Goose diet
The Magpie Goose, found abundantly in the tropical wetlands of northern Australia, is a large black-and-white goose with a prominent, rounded knob on its forehead and naked red skin on its face. It is the only goose in the world that can sleep in trees, thanks to its strong hind toe that provides a secure grip on branches.
The Magpie Goose is almost entirely vegetarian, feeding on aquatic vegetation, blades of grass, seeds, bulbs, and rhizomes dug from underground using its hooked bill. They congregate in large, noisy flocks of up to a few thousand birds to feed. Magpie Geese often forage in water for submerged vegetation and the corms of water chestnuts, submerging their head, neck, and forebody, but they do not dive.
During the breeding season, two females lay their eggs on a floating platform of reeds made by a single male. Once the eggs hatch, the three parents feed the chicks by bending tall grasses with their feet so that the goslings can eat the seeds.
The Magpie Goose plays an integral role in the lives of Aboriginal people across northern Australia, who hunt the geese and their eggs for food. However, they are considered agricultural pests and have been affected by the ongoing draining of wetlands for additional farmland, which destroys their breeding habitat.

Australian Shelduck diet
The Australian Shelduck, also known as the chestnut-breasted shelduck or mountain duck, is a member of the Anatidae bird family. It is found across southern Australia and Tasmania, and has a size range of 56-72 centimetres, with a wingspan of 94-132 centimetres.
The Australian Shelduck is an upright grazer that feeds on pasture and wetlands. Its diet consists of a variety of food sources, including tubers, plant material, insects, crustaceans, and molluscs. They are known to eat saltbush and samphire, and also feed on grass and insects.
These ducks are not popular game birds, so they have not been overhunted. However, they are occasionally hunted due to their habit of grazing in agricultural fields and damaging crops. Despite this, their populations have grown in recent years due to increased agricultural irrigation and the construction of new water impoundments, which provide more food and habitat.
The Australian Shelduck has a unique feeding technique, dabbling and filtering the water to capture their food. They are not diving birds, but young ducklings dive freely, and adults will dive when wounded or frightened.

Frequently asked questions
The diet of an Australian duck depends on its breed and its age. For example, wild Mallard ducklings feed on insects and other small invertebrates, while adults are mostly vegetarian. The Australian Wood Duck, on the other hand, eats grasses, grains, clover, herbs, and occasionally, insects.
The Australian Wood Duck is a medium-sized goose-like duck with a dark brown head and a pale grey body. It is found in a variety of environments, including grasslands, wetlands, and urban parks.
In addition to calories, ducks require proteins, essential amino acids, fats, and various vitamins and minerals. Domestic ducks require high-quality commercial food to stay healthy, while wild ducks should be fed natural foods like seeds and vegetables.
