How do hummingbirds survive when the weather is changing?

Hummingbirds survive changing weather by entering a state called torpor, which is a temporary hibernation that allows them to conserve energy during cold or harsh conditions. During torpor, their metabolic rate significantly decreases, and they can lower their body temperature, reducing their need for food. They also seek shelter in dense vegetation to protect themselves from wind and rain. Additionally, they may migrate to warmer regions if conditions become too extreme.
