OSTI ID:381563
Black oystercatchers (Haematopus bachmani) were studied in central Prince William Sound, Alaska, to determine the effects that the Exxon Valdez oil spill had on their population, reproductive biology, and behavioral ecology. Estimates of direct mortality of black oystercatchers varied widely among the methods used to assess losses and ranged from 4% to 57% of the population inhabitating the spill zone; mortality probably did not exceed 20% of the population. Although the black oystercatcher population appears to be recovering in some areas of the Sound, delayed reproduction in the species precludes determination of the total effect of the spill on the population until at least 1994.
