Black swans are almost entirely vegetarian.  They feed mainly on algae and submerged weeds, which they pull up by ‘updending’ – tipping forward and reaching their long necks down below the surface, their bottoms in the air and their legs comically waggling in the air.  In shallower water black swans are able to dabble – filter-feeding at the water’s surface, or dip its head to feed on plants just under the water’s surface.  When conditions are good it is also common to see black swans grazing on pasture on shore.
