Migración y hibernación: ¿qué es la hibernacion?

The video explains how some animals migrate to warmer areas during winter, while others hibernate. Hibernation is a deep sleep that helps animals like bears, snakes, and turtles survive harsh weather by reducing their heart and breathing rates. These animals do not eat or move for months.
