To get through the night without making dozens of food runs, hummingbirds go into a kind of nocturnal hibernation, lowering their body temperature and heart rate so they can get some rest. They can digest a fruit fly, soft insect, or spider in 10 minutes. Some hummers have been observed visiting 20 flowers a minute, and with their hover-and-sip style of feeding, they keep beating their wings and working out even while they eat.īecause they eat so much, hummers must digest their food quickly. That’s about 77 times as much as most humans eat! The hummingbird’s need for lots of calories is due to its high heart rate and small body size.
That may not seem like much, but if humans (who may eat 3,500 calories a day) had the metabolism of a hummingbird, they would have to consume approximately 155,000 calories a day. These petite birds consume between 3.14 and 7.6 calories a day. Their diet is mostly liquid-nectar-and these birds get plenty of exercise with all that zipping around just to get from sip to sip. Like a helicopter, a hummingbird can go up, down, sideways, backward, and even upside down! They can beat their wings from 20 to 200 times per second.

When it comes to flying, nobody does it better. Their name refers to the humming sound made by their tiny, beating wings each species creates a different humming sound, depending on the speed of its wing beats.
