What animals don't hibernate?

Common animals that don't hibernate are pigs, cats, dogs, sheep, rabbits, geese, magpies and sparrows.

Hibernation (also known as winter sting) is an extreme but regular decline in body temperature, metabolism and other physiological activities, which is an adaptation to reducing energy consumption. Hibernating species can be roughly divided into active hibernating animals and passive hibernating animals. For the latter, such as hamster, external factors, including photoperiod, food and external temperature, play a major role in the timing of this hibernation cycle.

Many animals don't hibernate. Except for cold-blooded animals, such as snakes, turtles and frogs, many mammals don't hibernate (bears in cold areas have hibernation habits). Chickens, ducks, geese, dogs, cows, sheep, pigs, horses and many birds that are normal in cold regions do not hibernate.

The body temperature does not change with the temperature of the external environment, and animals that remain relatively stable are called warm-blooded animals. Animals whose body temperature can be regulated by the change of environmental temperature are called thermogenic animals. When winter is cold, their body temperature drops and their activities stop. At this time, their energy consumption is also reduced, so they can maintain their lives without eating food.
