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.
This duck feeds on vegetation by grazing or dabbling [3] and to a lesser extent on small fish, invertebrates, and seeds. It can become a problem to rice farmers. Knob-billed ducks often perch in trees. They are typically seen in flocks, small in the wet season, up to 100 in the dry season. Sometimes they separate according to sex. [8]
Instead, the wings are used like paddles to help skim rapidly across the surface of the water. This species outweighs any other wild species called "duck" and is about the same mass as the largest wild geese in the world, although this species is only distantly related to most true ducks (for example of the genus Anas). On males, the head and ...
Common pochards feed on plant material (including seeds), small fish, molluscs, and other aquatic invertebrates. [13] [19] They feed primarily by diving to retrieve items from under the water's surface; however, they will also upend and dabble at items on the water's surface. They do most of their feeding at night.

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 ]
Chicks can jump from as high as 50 feet, surviving by landing either in water, or on top of soft material such as leaf litter. [18] The mother calls them to her and guides them to water. [17] The ducklings can swim and find their own food by this time. Wood ducks prefer nesting over water so the young have a soft landing.
Though classified as a diving duck, this pochard feeds more like a dabbling duck feeding on seeds roots, sedges, aquatic plants and other grasses. [ 2 ] [ 3 ] Netta is Ancient Greek for "duck" and peposaca is a transcription of the Guaraní name of this species which means "showy wings", referring to the broad white stripe that is only visible ...
