Hibernation is a solution to the problem of seasonal food shortage. Essentially, it is a physiological solution. Although behavior such as preparation of the nest and provision of the burrow with food may be important, the lowering of metabolic energy expenditure is central to hibernation. In contrast migration, although accompanied by physiological changes such as premigratory fattening and endocrine involution, is essentially a behavioral solution, a moving of the whole animal to the abundance of other habitats. Hibernation is physiological acceptance of reduced energy sources: migration is behavioral defiance of local conditions.
