That
humming you hear is a hummingbird's
wings as they beat up to 200 times a second. It takes a lot of energy
to dart between flowers, hover in mid-air, fly backwards, and impress
a mate! Hummingbirds burn food energy so fast that they need to
eat 1 1/2 to 3 times their weight in food each day. If they didn't,
they'd starve!
How
much food would you have to eat today
if you burned energy as fast as this hummingbird does?
