Black Duck feeding behaviour

[John Leonard <>]

Saw this behaviour today and, although it isn't earth-shattering, it's very cute.

Two Black Ducks were swimming and feeding on algae in a narrow stream
of water at the bottom of a drainage channel in suburban Canberra.
Their method of feeding was to approach the edege of the 1m wide stream
and paddle with their feet, scraping off the alga growing on those
surfaces; they would then submerge the head and, presumably, catch the
loosened filaments in their beak.
