American black bear
The American black bear (*Ursus americanus*) is a bear species native to North America and the most widely distributed bear on the continent.
The American black bear is the most widely distributed bear species in North America, found from Canada to Mexico. Despite its name, its fur can be black, brown, cinnamon, blue-grey, or rarely white.
What it is
The American black bear (*Ursus americanus*) is a medium-to-large omnivorous bear native to North America. It has a straight facial profile, rounded ears, non-retractable claws, and a flat back without the prominent shoulder hump seen in brown bears. Coat colour varies widely, making it an unreliable identifier.
Key details
Adults typically measure 1.5–1.8 m in length and weigh 90–272 kg, though size varies by sex, age, and season. They live 15–25 years in the wild and are listed as least concern. Their diet is mostly plant-based—grasses, berries, nuts—but includes insects, carrion, and small mammals.
Why it matters
Black bears are common in Canadian forests and near rural communities, making them a familiar wild mammal. While usually shy, they can become dangerous when attracted to human food or garbage. Understanding their behaviour helps reduce conflicts and supports coexistence.
In short
- Most common bear species in North America, ranging from Canada to Mexico.
- Omnivorous diet dominated by plant matter like berries and nuts.
- Fur colour varies widely; not a reliable way to identify species.
- Generally avoid humans but can be risky when food-conditioned.
American black bears are widespread in Canada and are one of the most familiar large wild mammals for Canadian readers, especially in forested regions and near rural communities.
