The Pacific black duck is mainly vegetarian, feeding on seeds of aquatic plants. This diet is supplemented with small crustaceans, molluscs and aquatic insects. Food is obtained by 'dabbling', where the bird plunges its head and neck underwater and upends, raising its rear end vertically out of the water.
In cooking and gastronomy, duck or duckling is the meat of several species of bird in the family Anatidae, found in both fresh and salt water. Duck is eaten in many cuisines around the world. It is a high-fat, high-protein meat rich in iron. Duckling nominally comes from a juvenile animal, but may be simply a menu name.
They mainly eat vegetation or insects near to the water, consuming animals such as larvae, crustaceans, and mollusks. They likewise eat plant foods: leaves as well as seeds, grains, and nuts. Many assume that the falcated duck helps disperse seeds over large areas because of their diet. These ducks are primarily herbivorous.
Commercial bird food is widely available for feeding wild and domesticated birds, in the forms of both seed combinations and pellets. [9] [10]When feeding wild birds, the Royal Society for the Protection of Birds (RSPB) [11] suggests that it be done year-round, with different mixes of nutrients being offered each season.

This polyculture yields both rice and ducks from the same land; the ducks eat small pest animals in the crop; they stir the water, limiting weeds, and manure the rice. Other rice polycultures in the region include rice-fish-duck and rice-fish-duck- azolla systems, where fish further manure the rice and help to control pests.
