Correct sentence: Eagles live on cliffs and raise their chicks in large nests.
Why this is correct (step by step):
- Capital letters: Use a normal capital at the start: write "Eagles" not "EAGLES." All caps looks like shouting.
- Where they live: Say "live on cliffs." You can say "up on cliffs" when talking, but "on cliffs" is shorter and correct.
- Matching words: "Eagles" is plural (more than one), so we use the verb "live" (not "lives").
- Their chicks: "Their" is the right word to show the nests belong to the eagles. "Chicks" means baby eagles.
- End with a period: Put a dot at the end of the sentence.
Two short versions you can also use:
- Eagles live on cliffs.
- They raise their chicks in large nests.
