In previous studies, bones from archeological midden deposits on Kodiak and Amchitka Islands, Aleutians, were erroneously identified as belonging to Great Cormorant (Phalacrocorax carbo), Pallas's Cormorant (P. perspicillatus), and Japanese Cormorant (P. capillatus), none of which is otherwise known from Alaska. These specimens are all re-identified as having come from the Double-crested Cormorant (P. auritus), which is much larger in Alaska than in middle and southern latitudes in North America.
