Atlantic puffin
The Atlantic puffin is a species of seabird in the order Charadriiformes. It is in the auk family, Alcidae, which includes the guillemots, typical auks, murrelets, auklets, puffins, and the razorbill. The rhinoceros auklet ("Cerorhinca monocerata") and the puffins are closely related, together composing the tribe Fraterculini. The Atlantic puffin is the only species in the genus "Fratercula" to occur in the Atlantic Ocean. Two other species are known from the northeast Pacific, the tufted puffin ("Fratercula cirrhata") and the horned puffin ("Fratercula corniculata"), the latter being the closest relative of the Atlantic puffin.
