Sloth Bear - Behavior

Behavior

Adult sloth bears may travel in pairs, with the males being gentle with cubs. They may fight for food. They walk in a slow, shambling motion, with their feet being set down in a noisy, flapping motion. They are capable of galloping faster than running humans. Although they appear slow and clumsy, sloth bears are excellent climbers. They climb to feed and rest, though not to escape enemies, as they prefer to stand their ground. They are capable of climbing on smooth surfaces and hang upside down like sloths. They are good swimmers, and primarily enter water to play. To mark their territory, sloth bears will scrape trees with their forepaws, and rub against them with their flanks. Sloth bears have a great vocal range. Gary Brown, in his Great Bear Almanac lists over 25 different sounds in 16 different contexts. Sounds such as barks, screams, grunts, roars, snarls, whickers, woofs and yelps are made when angered, threatening or when fighting. When hurt or afraid, they shriek, yowl or whimper. When feeding, sloth bears make loud huffing and sucking noises, which can be heard over 100 metres away. Sounds such as gurgling or humming are made by bears resting or sucking their paws. Sows will emit crooning sounds to their cubs. The species is the most vociferous when mating, and make loud, melodious calls when doing so. Sloth bears do not hibernate. They make their day beds out of broken branches in trees, and will rest in caves during the wet season. Sloth bears are the most nocturnal of bears, though sows become more active in daytime when with cubs.
