Puffins are any of three small species of auk (or alcids) in the bird genus Fratercula with a brightly coloured beak in the breeding season. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the Tufted Puffin and Horned Puffin, are found in the North Pacific Ocean, while the best known species, the iconic Atlantic Puffin, is found in the North Atlantic Ocean. These birds are taken in Iceland.
