    Atlantic puffins (海雀) spend most of their life at sea. When it's time to lay eggs, the birds gather on seaside cliffs. They dig into the ground to build nests. After a chick was born, it spends six weeks in the nest, feasting on fish supplied by its parents. Then the young bird must look after itself. It leaves the nest and flies to the sea.

But on Heimaey, an island off the coast of Iceland, human-made objects have disrupted the chicks’ trip to the ocean. Luckily, they are getting help from the children of Heimaey.

Instinct tells chicks to follow the light of the moon to the sea, but they are confused by Heimaey’s bright lights. Each year, a large number of them end up lost, or worse. Often, the birds are hit by cars or caught and eaten by cats.

Each breeding season, the children of Heimaey form search parties. They carry flashlights and cardboard boxes. “When you see a bird, you try to corner it and herd it into the box,” said Eldur Hansen. Eldur is 14 and he has caught several puffins this way. Each year, they rescue thousands of chicks. Children take rescued birds home. The next morning, they take them to the beach for release.

Before releasing the chicks, the children make a stop at the local aquarium, where the birds are weighed and tagged for tracking purposes. This helps scientists learn more about puffins.

Atlantic puffins are now listed as a rare species. That means they are likely to become endangered. The main reason is that the ocean’s supply of small fish is diminishing. This is tied to overfishing and rising ocean temperatures.

Erpur Hansen, Eldur Hansen’s dad, is with the South Iceland Nature Research Center. He said the children’s action was more important than ever. Thanks to data gathered with the children’s help, researchers have learned that chicks now weigh less than in previous years. That means they have a lower chance of survival. Researchers worry that puffins will die out if ocean temperatures continue to rise, but the children’s rescue inspires them.
