We tested the hypothesis that segregation in wintering areas promotes population differentiation in a sentinel North Pacific seabird, the rhinoceros auklet (Cerorhinca monocerata). We collected tissue samples for genetic analyses on five breeding colonies in the western Pacific Ocean (Japan) and 13 in the eastern Pacific Ocean (California to Alaska), and deployed light-level geologgers on 12 eastern Pacific colonies to delineate wintering areas. Loggers were deployed previously on one colony in Japan. There was strong genetic differentiation between populations in the eastern vs. western Pacific. Deep-ocean habitat along the northern continental shelf appears to act as a barrier to dispersal; abundant in the western and eastern Pacific Ocean, the rhinoceros auklet is virtually absent as a breeder in the Aleutian Islands and Bering Sea, and no loggered birds crossed the North Pacific in the non-breeding season. Late Pleistocene glaciation over the North Pacific also might have forced a southward range shift ... : missing data 0 ...
