Polar Bear Cub Sounds

What sound does a polar bear cub make?

Polar bear cubs make soft humming, cooing, and buzzing sounds when they're warm and content — especially while nursing. Scientists call this happy nursing noise a 'chuffing hum', and it's one of the coziest sounds in the Arctic.

When a cub is cold, hungry, or separated from its mother, it squeals and cries loudly until she returns. Mother polar bears answer with gentle chuffs and grunts to guide their cubs back to safety.

About the Polar Bear Cub

Polar bear cubs are born in the depths of Arctic winter, usually in pairs. At birth, they are blind, toothless, and covered with short, soft fur. Cubs weigh only about 1 pound at birth but grow rapidly on their mother's rich milk. For the first few months, the family remains in a den where the cubs are protected from the harsh Arctic environment. As they grow, the cubs learn vital skills like hunting and swimming from their mother. Their playful nature is not just cute but serves as important practice for adult survival skills.
