It is a well known fact that hummingbirds have a very fast metabolism, but have you ever considered how that compares with a human’s? If the average man’s metabolism was comparable to that of a hummingbird, he would have to eat 285 pounds of hamburger every day in order to maintain his weight. That is astonishing! If we had to eat that much every single day just to survive think of how much we would weigh. It may also surprise you to know that a hummingbird can starve to death in as little as two hours. This is why the hummingbird will eat between 5-8 times per hour with each feeding lasting about 30 seconds in length.
