Growl, Bark & Huff

Bears make a variety of vocalizations that sound like a growl, bark, or huff which means the bear is agitated, angry, or annoyed. 

These sounds are usually accompanied by body language that indicates the bear is ready to attack or defend itself. The huffing sound a bear makes is often mistaken for snorting, which is common in domestic dogs.

Squeal & Whimper

A squeal or whimper means that a bear is in distress or pain. They make this noise when they feel threatened or scared. 

Cubs sometimes whimper to let their mother know that they need her. 

If you hear a squeal or whimper, back away slowly and leave the area. Do not try to approach the bear. It is best to give them space and allow them to calm down on their own.

Mumble & Purr

A mumble or purr means contentment. 

A mumble is usually made when a bear is content and happy. Cubs will often mumble when they are cuddling up to their mother. 

The purr is another sound of contentment, and it’s similar to the purr of a cat. It’s usually used as a sign of happiness or friendliness. Bears will sometimes purr when they’re eating because it means that they’re enjoying what they’re eating.

What Sound Does a Polar Bear Make?

Polar bears have several vocalizations which have been determined to be associated with distinct situations or motivations for making noise. 

Their most often vocalization is likely what is called an aggressive huff a low-frequency snorting sound that may serve as an agonistic signal between animals. 

These huffs take three forms and are emitted in varying contexts during social encounters, when encountering prey or a threat, and as an alarm call.

Polar bear cubs will also let out small pulses of vocalizations, which are used to stimulate milk production in their mother.[1]

Additional Bear Communication

Body Language

The body language of a bear says a lot. They use their body to display dominance or submission, play, and more.

When a bear stands tall and erect, with its chest out and head held high, it is displaying dominance. This posture is often used to show other bears who are in charge, or when they are trying to scare off predators or people. 

A submissive bear will usually hunch over, keeping its head down and its tail tucked between its legs.

Bears also use their body positioning to communicate what they’re feeling. 

When two bears meet each other, they’ll often stand on their hind legs and “hug” each other with their front paws. This position is called the “bear hug” and it’s a way of fighting.

Facial Expression

Depending on how a bear holds its head, places its ears, and uses its mouth, it can communicate different things:

  • When a bear’s mouth is open and its lips are pulled back, it shows aggression. 
  • When a bear curls its upper lip (called the snarl), it’s very angry. 
  • If a bear sticks out its tongue, it’s trying to be friendly.

Bears Use Communication to Avoid Fighting

Bears prefer not to fight. Instead of fighting when they come across another bear, they’ll use vocalizations, body language, and facial expressions.

Bears avoid a fight by using vocalizations and posturing[4]. This can help prevent serious conflicts and injuries and along with this, conserve the energy they need to survive.

They make a lot of sounds, from growling, barking, and huffing, to mumbling, purring and whimpering. They use vocalizations to communicate with each other as well as facial expressions and body positioning.

The purpose of all these different sounds is usually to resolve conflicts before they get out of hand or to avoid them altogether. 

For example: if two bears encounter each other in the forest, they may give a few warning huffs. The stronger of the two bears will act dominant, to make the other bear show submission.


Bears make a variety of sounds depending on their mood or the situation they are in. These vocalizations can be used to communicate with each other, as well as display dominance, submission, and happiness. 

Bears often use body language and facial expressions along with their vocalizations to get their point across. In general, bears try to avoid fighting and will use communication to resolve conflicts peacefully.
