AB  - Ocean-scale monitoring of pollution is challenging. Seabirds are useful 
      indicators because they travel over a broad foraging range. Nevertheless, this 
      coarse spatial resolution is not fine enough to discriminate pollution in a finer 
      scale. Previous studies have demonstrated that pollution levels are higher in the 
      Sea of Japan and South and East China Seas than the Northen Pacific Ocean. To 
      test these findings in a wide-ranging animal, we tracked streaked shearwaters 
      (Calonectris leucomelas) from four islands in Japan using global positioning 
      system (GPS) and measured persistent organic pollutants (POPs) in the oil of 
      their preen glands. The POPs did not change during 6 to 21 days when birds from 
      Awashima were foraging only in the Sea of Japan, while it increased when they 
      crossed to the Pacific through the Tsugaru Strait and foraged along the eastern 
      coast of Hokkaido where industrial cities occur. These results indicate that POPs 
      in the oil reflect relatively short-term exposure. Concentrations of POPs 
      displayed greater variation among regions. Total polychlorinated biphenyls were 
      highest in birds foraging in a small area of the semiclosed Seto Inland Sea 
      surrounded by urbanized coast, p,p'-dichlorodiphenyltrichloroethane (DDT) was 
      highest in birds foraging in the East China Sea, and total hexachlorocyclohexanes 
      were highest in birds foraging in the Sea of Japan. All were lowest in birds 
      foraging in the Pacific. This distribution of POPs concentration partly agrees 
      with previous findings based on mussels, fish, and seawater and possibly reflects 
      the mobility and emission sources of each type of POP. These results highlight 
      the importance of information on the foraging area of highly mobile top predators 
      to make them more effective monitors of regional marine pollution.
