Scientists have used a high-speed camera to film hummingbirds’ aerial acrobatics at 1000 frames per second. They can see, frame by frame, how neither wind nor rain stop these tiniest of birds from fueling up.
With spring in full bloom, hummingbirds can be spotted flitting from flower to flower and lapping up the sugary nectar inside.
These tiniest of birds have the highest metabolism of any warm-blooded animal, requiring them to consume their own body weight in nectar each day to survive.
By comparison, if a 150-pound human had the metabolism of a hummingbird, he or she would need to consume the caloric equivalent of more than 300 hamburgers a day.
Hummingbirds don’t just hover to feed when the weather is nice. They have to keep hovering and feeding even if it’s windy or raining, a remarkable feat considering most of these birds weigh less than a nickel.
