Question: how many calories do hummingbirds consume?
Answer: These petite birds consume between 3.14 and 7.6 calories a day. 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. That's about 77 times as much as most humans eat!
