==Food==
Hummingbirds are called "nectivores" because about 90 percent of their diet is nectar from flowers. hummingbirds slender bills wheich are perfect for collecting nectar from flowers. The bills allow each kind of hummingbird to feed from specific types of flowers. They also protect their long split tongues. Although their main diet is nectar, they sometimes eat insect which are often caught by "hawking". Hawking is when a hummingbird catches insects by flying and diving to snap them up out of the air. Hummingbirds consume between 3.14 and 7.6 calories a day. Humans (who may eat somewhere around 3,500 calories a day) would have to consume approximately 155,000 calories a day if they had the metabolism of a hummingbird. This is about 77 times the amount which humans usually eat.
