The seeds are high in energy, and this energy is also important for controlling temperature stressors. [3] Though they are classified as diving ducks, they feed by dabbling on the surface of the water, upending in shallow water and occasionally grazing on land, but they rarely dive. [2]
Ducks eat pests (e.g. brown planthoppers) in the crop; they stir water, limiting weeds, and manure the rice. Surface must be even; water depth must suit ducks; young ducks best as they don't nibble rice leaf tips. [5] Rice-fish-duck: China: Fishes bred on rice terraces: Fattens ducks and fish, controls pests, manures the rice.
A mixture of seeds in a bird feeder. Bird food or bird seed is food intended for consumption by wild, commercial, or pet birds. It is typically composed of seeds, nuts, dry fruits, flour, and may be enriched with vitamins and proteins. [1] Bird food can vary depending upon dietary habits and beak shapes.

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.
The canvasback feeds mainly by diving, sometimes dabbling, mostly eating seeds, buds, leaves, tubers, roots, snails, and insect larvae. [3] Besides its namesake, wild celery, the canvasback shows a preference for the tubers of sago pondweed , which can make up 100% of its diet at times. [ 10 ]
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
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. [15] [16]
