Abstract: | We measured mercury concentrations ([Hg]) and nitrogen stable isotope ratios (delta N-15) in the primary feathers of Short-tailed Shearwaters (Puffinus tenuirostris) that were tracked year-round. The [Hg] were highest in 14 birds that used the Okhotsk and northern Japan Seas during the non-breeding period (2.5 +/- A 1.4 mu g/g), lowest in nine birds that used the eastern Bering Sea (0.8 +/- A 0.2 mu g/g), and intermediate in five birds that used both regions (1.0 +/- A 0.5 mu g/g), with no effects of delta N-15. The results illustrate that samples from seabirds can provide a useful means of monitoring pollution at a large spatial scale. |
