'''Hibernation''' is a behaviour of certain animals, particularly in cold climates, of entering a prolonged physically inactive state of lowered metabolic activity, as a means of coping with the vicissitudes of [[winter]]. While many animals will sleep more than usual during the winter, true hibernation involves dramatically reduced heartrates and body temperatures, generally over a single unbroken period of torpor.
Animals that hibernate include [[bear]]s, the [[dormouse]], the [[hedgehog]], and many types of [[reptile]]s and [[amphibian]]s.
Most [[bird]]s use [[migration]] to avoid harsh seasonal conditions; the common poorwill, a type of [[nightjar]], is the only bird known to hibernate. Historically, [[swallow]]s were believed to hibernate at the bottom of ponds.
Animals which become inactive is summer are said to [[Aestivation|aestivate]].
