A female bear is called a sow. This term is commonly used to refer to adult female bears, particularly those that have given birth. However, there are different names for female bears depending on the species and the age of the bear.

First, let’s take a look at the different species of bears and the names given to female bears:
- Grizzly bears: Female grizzly bears are also known as sows. These bears are known for their distinctive hump on their shoulders and can be found in North America, particularly in Alaska and western Canada.
- Black bears: Female black bears are also referred to as sows. They are smaller than grizzly bears and can be found in many parts of North America, including Canada and the United States.
- Polar bears: Female polar bears are called sows as well. These bears live in the Arctic region and are adapted to the extreme cold weather.
- Brown bears: Female brown bears are commonly known as sows, but in some regions, they are referred to as she-bears. These bears are found in many parts of the world, including North America, Europe, and Asia.
- Asiatic black bears: Female Asiatic black bears are also called sows. These bears are found in many parts of Asia, including China, Japan, and Korea.
Now, let’s take a look at the different names given to female bears based on their age:
- Cubs: Baby female bears are called cubs, regardless of the species.
- Yearlings: Female bears that are one year old are called yearlings. They are still considered cubs but are more independent and are beginning to explore on their own.
- Subadults: Female bears that are between one and four years old are called subadults. They are still developing their hunting and survival skills and are not yet fully mature.
- Adults: Female bears that are four years or older are considered adults. They are fully mature and capable of reproducing.
It’s worth noting that male bears also have different names depending on their age and species. For example, male grizzly bears are called boars, while male black bears are called boars or bears. Male polar bears are called boars as well, while male brown bears are referred to as boars or bruins.
In conclusion, the term sow is commonly used to refer to adult female bears of various species, including grizzly bears, black bears, polar bears, brown bears, and Asiatic black bears. However, female bears also have different names depending on their age, with cubs, yearlings, subadults, and adults being the most common categories.
