| Abstract: | During a period of 4 months prior to the 1978–1979 breeding season, a total of 157 Magellanic penguins (Spheniscus magellanicus) were found dead on 1 km of beach in Golfo San Jose, a site in the vicinity of the largest nesting colony for this species in Argentina. Sixty-two of 91 adults (68%) were oiled, but only one of 66 immatures was oil-stained. Of the penguins with oil on one side only, three times as many were stained on the left side as on the right. The absence of oiled Magellanic penguins seen at nearby nesting colonies supports the hypothesis that these birds are not fit to breed. |
