The black-and-white seabird that is the only living Fratercula species found in the Atlantic is the Atlantic puffin.
The Atlantic puffin, Fratercula arctica, is a member of the auk family, Alcidae. It breeds around the North Atlantic, including Iceland, Britain, Ireland, Norway, Greenland, Newfoundland and Labrador, and the Faroe Islands. Its compact body, upright stance, colorful breeding-season bill, and black-and-white plumage make it one of the most recognizable seabirds.
The genus Fratercula contains three living puffin species, but only the Atlantic puffin occurs in the Atlantic Ocean. The tufted puffin and horned puffin live in the northeastern Pacific, so they are not alternative answers to this question. The Atlantic puffin is also called the common puffin.
Its scientific names provide useful clues: Fratercula is derived from Medieval Latin for “little friar,” referring to the bird’s black-and-white, robe-like appearance, while arctica reflects its northern distribution. Puffins are auks, not penguins, and they can fly despite their somewhat penguin-like appearance.
