* Hiss: This is their most common sound, used as a warning. It's a sharp, exhaled "sss" sound.
* Growl: A deeper, more guttural sound, also used to express aggression.
* Chirp or whistle: These sounds are more common among young skunks.
* Screeches or yelps: These are rare but can be heard when skunks are in pain or highly distressed.
It's important to remember that a skunk's primary defense mechanism is its spray, not its sounds. They are more likely to hiss or growl as a warning before resorting to spraying.
