Atlantic Puffins spend most of their time at sea. They only come to land during the breeding season, from April to August. They nest inside burrows in colonies on northern seacoasts and rocky islands. The rest of the year, puffins are on the open ocean.
The Atlantic Puffin is the only species of puffin found on the Atlantic coast. Maine's Seal Island is home to about 500 of these colorful, pigeon-sized sea birds.
