The species of bear native to North America is the American black bear (Ursus americanus). This species is widespread across various habitats, including forests, swamps, and mountainous areas. They typically range from Canada to Mexico and are known for their adaptability to different environments. American black bears have a varied diet, consuming fruits, nuts, insects, and small animals. Another bear species, the polar bear (Ursus maritimus), is also found in North America, primarily in the Arctic regions, but it is mainly associated with sea ice rather than forests. Conservation efforts have been essential in protecting black bear populations.
