Essential Question

Unit 2 • Expository Text

EXPOSITORY TEXT FIND TEXT EVIDENCE

Bald eagles are birds. The baby birds, or offspring are called eaglets. Let’s read about how eaglets are like their parents.

Read Paragraph 1

Reread Reread and underline the sentence that explains what eaglets are.

All birds lay eggs. Bald eagles build their nests in the tops of trees so the eggs will be safe. Their nests are built of sticks and grass. They add on to their nests each year. They can become huge! These giant nests can be as large as nine feet across. That’s bigger than your bed!

Paragraphs 2-3

Main Topic and Key Details Circle the sentence that tells how eagles keep their eggs safe. What happens after the eggs hatch?

The mother eagle lays from one to three eggs. She sits on her eggs until they hatch. Then both parents watch over the nest.

SHARED READ FIND TEXT EVIDENCE Read Paragraph 1

Main Topic and Key Details Underline two ways eaglets need their parents.

At first, the eaglets are helpless. They cannot walk. They need their parents for food. They also cannot see well. Birds are not mammals. They do not have milk to feed their young. They hunt for food.

Eaglets also need their parents for safety.

Paragraph 2

Reread Circle what eagles use to hunt, fly, and catch fish.

Homographs In the last sentence, does live mean "to happen now" or "to stay alive"?

The eagles must bring food to the eaglets.

Reread

Accent Alaska.com/Alamy

Author's Craft

How does the author use description to show what an eaglet must learn?

10

Bald eagles use their sharp eyes to hunt.

They use their strong wings to fly fast.

They also use their claws and beak to catch fish. Young eaglets must learn all these things. Then they can live on their own.

Unit 2 • Expository Text

Unlike mammals, birds have feathers, not fur. An eaglet is born covered with soft gray down. It cannot fly until it grows dark feathers like its parents. The eaglet stays near the nest until its wings grow strong. That takes about five months.

Can you believe this powerful eagle began life as a helpless baby?
