The Whiskered Auklet, Aethia pygmaea, is a small seabird of the auk family. It has a more restricted range than other members of its genus, Aethia, living only around the Aleutian Islands and on some islands off Siberia (like Commander Islands), and breeding on these islands. It is one of the smallest alcids, only the closely related Least Auklet being smaller. Its name is derived from the long white feathers on its face that are part of its breeding plumage.
