The little-known Whiskered Auklet (Aethia pygmaea) occurs only in the Aleutian (Figure 1), Commander, and Kuril Islands of the North Pacific. In the Aleutian Islands, it occurs from Unimak Pass to the Near Islands (Kessel and Gibson 1978), but the only documented nesting records are from Umnak Island (R.J. Gordon in litt.), Chagulak Island (Murie 1959), Atka Island (Turner 1886), and Buldir Island (Knudtson and Byrd, in press).
This paper summarizes new information on the distribution of Whiskered Auklet in the Aleutian Islands and provides a significantly higher estimate of the minimum population.
