Ducks exploit a variety of food sources such as grasses, grains and aquatic plants, fish, insects, and the like. The sound made by some female ducks is called a "quack"; a common (and false) urban legend is that quacks do not produce an echo. The males (drakes) of northern species often have showy plumage, but this is moulted in summer to give a more female-like appearance, the "eclipse" plumage. In many species, moulting birds are temporarily flightless; they seek out protected habitat with good food supplies during this period. This moult typically precedes migration.
