Why are hummingbirds entergetic?

Hummingbirds are energetic due to their high metabolism, which is necessary to support their rapid wingbeat, often exceeding 50 beats per second. They have a unique ability to hover in place and fly in all directions, requiring immense energy. Their diet, primarily consisting of nectar, provides quick energy, while their small size allows for efficient energy use and rapid movement. This combination of physiological adaptations and dietary habits makes them some of the most energetic birds in the animal kingdom.
