What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do crossbills have beaks that cross at the tips?

The Big Idea

Some birds have beaks that cross at the tips! It looks like a mistake. But it's a perfect tool!

Hidden Seeds

Step one: Hidden Seeds. Crossbills eat seeds hidden inside pine and spruce cones. The cone's tough scales cover the seeds, so they are hard to reach.

Pry and Twist

Step two: Pry and Twist. The bird slides its crossed beak tips between the scales and twists to pry them apart. Then its tongue scoops out the seed.

Tiny Pliers

Step three: Tiny Pliers. A beak that crosses works like a tiny pair of pliers, perfect for this one job. Chicks hatch with straight beaks that cross as they grow.

A Closer Look

Let's take a closer look! Hides seeds. Pry scales apart. Scoops seeds. Straight at first.

Quick Facts

Quick facts! Some crossbills cross to the left and some cross to the right. Crossbills eat seeds from cones. Their beaks work like pliers. Crossbill chicks start out with straight beaks.

Think Like a Scientist

Now, think like a scientist! Set two books close together with a small crack between them. Put a raisin in the crack. Press tong tips together so they cross a little. Try to pull the raisin out. Why would crossed tips help?
