It is an animal of the order Carnivora, family Ursidae. It is also called American bear. It is called American black bear in contrast to Asiatic black bear in East Asia, but it is a different genus and species. It is distributed from Alaska in North America along the Rocky Mountains to Mexico, and also along the Gulf of Mexico. Its head and body length is 1.8 meters, and it weighs up to 200 kilograms. Its fur is usually black, but some have white spots on their forechest. It is omnivorous, mainly eating fruit and herbs, but also fish such as salmon. It may also destroy crops such as corn. It is a skilled tree climber, and like the Japanese black bear, it has a habit of peeling the bark of planted trees such as Douglas fir. This bear appears before visitors to American national parks such as Yellowstone. It will not harm humans if it is not provoked, but it is strong, so caution is required. [Hiroyuki Watanabe] They are found in North America, from Alaska along the Rocky Mountains to Mexico. Their coat is usually black. They are omnivorous, eating fruits and herbs, as well as fish such as salmon. They are skilled at climbing trees. They are also known as American bears.
