    Heimaey, an island in Iceland, is home to just about 4,200 people. But each spring, more than1.5million puffins (海鹦) visit Heimaey and its neighboring islands. They go there to breed(繁殖). Around August, puffin chicks head for the ocean.That’s when the trouble begins.

Puffin chicks usually follow the light of the moon to the sea. But Heimaey’s bright lights make them unable to think and act right.Each year,a large number of  them end up lost—-or worse. Often,some are hit by cars or eaten by cats.

Luckily, there is the Puffling Patrol.Each breeding season,the children of Heimaey work together to form search groups. At night they go to the streets carrying flashlights and cardboard boxes. “When you see a bird, you try to corner it and get it into the box,” Eldur Hansen said. The 14-year-old boy has caught several puffins this way. No one knows exactly when or how the Puffling Patrol got its start.But each year, it saves thousands of puffin chicks.

Puffins are now listed as a vulnerable species(易危物种).The main reason is that the number of small fish in the ocean is dropping. This is because of overfishing, pollution and rising ocean temperatures. Puffins need the fish for food.

Scientists worry puffins will die out if ocean temperatures continue to rise.But the Puffling Patrol inspires them a lot. “The message is that people can make a difference,” says Dr. Stephen W.Kress,an expert in seabird protection.
