What is a group of polar bears called?

A group of polar bears is called a "celebration" or sometimes referred to as a "sleuth." Polar bears are typically solitary animals, but they may come together in small groups on occasion, especially when food is abundant, such as during a seal kill. These groupings are usually temporary and do not involve any long-term social bonds. Polar bears are highly territorial animals and typically prefer to establish and maintain their own territories rather than form permanent social groups.
