Migration and Hibernation: What Is Hibernation?

The video explains how some animals migrate to warmer places in winter, while others hibernate. Hibernation is a deep sleep that helps animals like bears, snakes, and turtles survive cold months when food is scarce. During hibernation, animals' heart and breathing rates slow down, and some do not eat or move for months. As the weather warms, they wake up, with some bears even giving birth during this period. Hibernation is vital for survival as it allows animals to endure times when food is hard to find.
