The term 'Puffin Relative' is a reference to two species of seabirds, the Auklet (6 letters) and the AUK (3 letters). Both species are members of the Alcidae family, which includes puffins, guillemots, murres, and other seabirds. The Auklet is a small, chunky bird that lives in colonies along the coasts of the Pacific Ocean, while the AUK is a larger, more slender bird that lives in the North Atlantic and Arctic Oceans.
