Crested (Aethia cristatella) and Least Auklets (Aethia pusilla) are crevice-nesting birds that breed in large mixed colonies at relatively few sites in the Aleutian Chain, Bering Sea, Gulf of Alaska and Sea of Okhotsk. Time-lapse imagery of nesting habitat was collected over the summers of 2010, 2012, and 2013 to assess use of the primary pre-eruption colony site. At-sea surveys collected relative abundance data to identify shifts in distributions of Crested and Least Auklets around Kasatochi and Koniuji Islands.
