Although puffins spend most of their time far out at sea, they also rest on rocks and cliffs in large colonies.
These birds dig long burrows in the ground using their beaks and feet. Their eggs are laid in a little nesting chamber at the end of the underground burrow.
These birds live most of their lives at sea, resting on the waves when not swimming. They are excellent swimmers that use their wings to stroke underwater with a flying motion. They steer with rudderlike webbed feet and can dive to depths of 200 feet, though they usually stay underwater for only 20 or 30 seconds. Puffins typically hunt small fish like herring or sand eels.
Atlantic puffins land on North Atlantic seacoasts and islands to form breeding colonies each spring and summer. Iceland is the breeding home of perhaps 60 percent of the world’s Atlantic puffins. The birds often select precipitous, rocky cliff tops to build their nests, which they line with feathers or grass. Females lay a single egg, and both parents take turns incubating it. When a chick hatches, its parents take turns feeding it by carrying small fish back to the nest in their relatively spacious bills. Puffin couples often reunite at the same burrow site each year. It is unclear how these birds navigate back to their home grounds. They may use visual reference points, smells, sounds, the Earth’s magnetic fields—or perhaps even the stars.
