* For female ducks, it can be used as an alarm call to warn her ducklings of danger.
* For male ducks, it can be used to acknowledge a greeting from another duck or as a general greeting signal.
* As a signal from ducklings, it can be a basic call for their parents to get their attention.
- Repeated Quacks (Rapid): A series of rapid quacks from a duck signifies danger or excitement.
- Low Quack: A single, long, drawn-out quack from a duck signifies contentment.
- Soft, Rhythmic Quack: Ducks also tend to quack in a rhythmic manner during preening and bathing, expressing a calming and contented mood.
Cackles/Laughing Sounds

Hisses
- A hissing sound from a duck signifies agitation or annoyance, much like a low-pitched version of a cat’s hiss. Ducks might also emit hisses when faced with a serious threat, such as a predator.
Squeals
