Ducks not all they are quacked up to be

We all know that ducks quack. But do they really? Most male ducks are on the silent side, while female ducks make more noises.

While some quacking may be involved, vocalizations can also include hisses, purrs, grunts, squeaks, whistles, honks, and much more. Sounds differ according to need—for example, they might signal that the duck is begging for food, begging for love, or warning of danger.
