Hibernation is when an animal slows its heart rate to save energy and survive the winter without eating much. … During hibernation the animal’s body temperature drops, and its heartbeat and its breathing slow down so that it does not use much energy.

What is hibernation easy words?

An inactive state resembling deep sleep in which certain animals living in cold climates pass the winter. In hibernation, the body temperature is lowered and breathing and heart rates slow down. Hibernation protects the animal from cold and reduces the need for food during the season when food is scarce.

During hibernation, the animal’s body doesn’t need nearly as much energy to stay alive.

Do birds hibernate?

Birds do not generally hibernate as many mammals and reptiles will. They can enter a similar state called torpor, when they slow their body metabolism, lower their body temperature, and conserve energy until conditions improve.
