Hummingbirds have a high metabolism and can enter a state of torpor to conserve energy during cold nights, lowering their body temperature and heart rate.
Their tiny size allows them to quickly warm up in the morning sun. They also have specialized downy feathers that provide insulation against the cold.
Hummingbirds rely on nectar as their primary food source, but during colder months, they switch to feeding on insects to meet their energy needs.
To survive freezing temperatures, hummingbirds can enter a state of hypothermia where they lower their body temperature to avoid frostbite and conserve energy.
Some species of hummingbirds migrate to warmer regions during the winter, while others stay in their habitats and rely on their unique adaptations to endure the cold.
Despite their small size, hummingbirds have evolved remarkable strategies to survive cold weather, showcasing nature's resilience and adaptability.
