How do hummingbirds withstand temperatures?

Hummingbirds withstand extreme temperatures by entering a state of torpor, a form of hibernation that significantly lowers their metabolic rate and conserves energy. During torpor, their body temperature drops, allowing them to survive cold nights or harsh weather conditions. Additionally, they have high-energy diets consisting mainly of nectar, which provides the necessary calories to maintain their activity during warmer periods. Their unique physiological adaptations enable them to thrive in diverse environments, from tropical to temperate regions.
