Why do hummingbirds need to eat so often?
A hummingbird’s wings beat dozens of times each second, and its heart races. That takes huge amounts of energy, so the bird sips sugary nectar and eats tiny insects through the day. It may feed every 10 to 15 minutes. At night it can save energy by going into a deep, sleep-like rest called torpor, when its body temperature and heartbeat drop.

Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do hummingbirds need to eat so often?
The Big Idea
Hummingbirds are tiny but always busy. They seem to be eating all the time! Why do they need to eat so often?
Busy Wings
Step one: Busy Wings. A hummingbird's wings beat dozens of times each second. Its heart races too, and all that takes huge amounts of energy.
Snack Time
Step two: Snack Time. So the bird sips sugary nectar and eats tiny insects all through the day. It may feed every 10 to 15 minutes.
Torpor
Step three: Torpor. At night, a hummingbird can save energy by going into a deep, sleep-like rest called torpor. Its body temperature and heartbeat drop until morning.
A Closer Look
Let's take a closer look! Dozens of beats a second. Sugary fuel. Protein snacks. Night saver.
Quick Facts
Quick facts! A hummingbird may feed every 10 to 15 minutes. Torpor helps a hummingbird make it through a cold night. Their hearts race very fast. They eat tiny insects too.
Think Like a Scientist
Now, think like a scientist! With a grown-up, watch a hummingbird feeder or flowers for 10 minutes. Count the visits. If there are no hummingbirds nearby, watch a video. How long does each visit last? Why do you think they come back so often?
Outro
A hummingbird's wings and heart work super fast, which burns huge amounts of energy. It sips nectar and eats tiny insects every 10 to 15 minutes, and at night it rests in torpor to save energy. Science is amazing! Remember, every big discovery starts with a small question. Keep looking, keep learning, and keep asking why!
