When we think of social animals-that is, animals who live together in well-defined groups, and form enduring relationships- we usually think of the great apes, of wolves and other members of the dog family, and, or course, of humans. Science considers bears to be solitary animals. But while bears don't live in established groups or obey rigid hierarchies as chimps and wolves do, they have amazingly complex social relationships.
