They use cliffs for burrows to raise their young. When they are three months old the pufflings are ready to go to sea. They also use the cliffs in Iceland for taking off because they can't take off on flat ground. Puffins have long journeys to sea. Some puffins fly more than a thousand miles in 8 weeks.
Some puffins fly to different countries along the Atlantic shores.
Pufflings know when to leave their burrows. When the baldursbroh, a flower in Iceland, blooms they know it is time to leave the island. In Norway they are called Lunde. Puffins mate when they are 5 years old. They tap their beaks when they mate.
