Why does a bird preen its feathers all day?

Video · 1:50 · Crafty Clover explains, from A Million Whys Book 31

Feathers are made of tiny barbs that hook together like a zipper. Flying, wind, and rain can pull those hooks apart. When a bird preens, it slides each feather through its beak to zip the barbs back together. Preening also removes dirt and tiny bugs and keeps the feathers smooth, which helps the bird stay warm, dry, and ready to fly.

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does a bird preen its feathers all day?

The Big Idea

Birds spend lots of time fixing their feathers. It looks like they are always grooming. Why does a bird preen all day?

Tiny Hooks

Step one: Tiny Hooks. Feathers are made of tiny barbs that hook together like a zipper. Flying, wind, and rain can pull those little hooks apart.

Zipping Up

Step two: Zipping Up. When a bird preens, it slides each feather through its beak. That zips the barbs back together, so the feather is whole and smooth again.

Clean and Ready

Step three: Clean and Ready. Preening also removes dirt and tiny bugs from the feathers. Smooth, clean feathers help the bird stay warm, dry, and ready to fly.

A Closer Look

Let's take a closer look! Tiny branches. Hold them together. Zips them up. Ready to fly.

Quick Facts

Quick facts! A bird can spend a large part of each day preening. Feathers zip together like a zipper. Preening removes tiny bugs. Neat feathers help keep birds dry.

Think Like a Scientist

Now, think like a scientist! Sit at a window or park bench. Watch one bird for five minutes. Count how many times it preens. Write down which body part it cleans first. Does it preen more after a bath or a flight?

Outro

Feathers have tiny barbs that hook together like a zipper, and flying, wind, and rain pull them apart.
