7 . The Amazing Journey of Arctic Terns?

Arctic terns are small birds with a big adventure. Every year, they travel from the Arctic to the Antarctic and back—this is the longest migration of any animal on Earth. The round trip can be over 70,000 kilometers!?

Why do they make such a long journey? In summer, the Arctic is full of daylight, and there are plenty of insects for them to eat. They lay their eggs there. When winter comes, the Arctic gets dark and cold, so the terns fly south to the Antarctic, where it is summer and food is still easy to find.?

The journey is not easy. They must fly over oceans and deserts, facing strong winds and hungry predators. But Arctic terns are smart. They follow the sun and stars to find their way. They also fly in groups to stay safe.?

Scientists are amazed by these birds. Their bodies are built for long flights—they have strong wings and light bones. Even young terns can make the journey without their parents guiding them. This amazing ability has helped them survive for millions of years.?
