dc.description.abstractIn the winter of 2002–03 the Prestige tanker spilled 60,000 tons of oil over the northern half ofthe Iberian Coastal Large Marine Ecosystem (northern Portugal to France). Most (c. 85%) of the 22,981 oiledseabirds reported were alcids (i.e., auks): Common Murres (Uria aalge), Razorbills (Alca torda) and AtlanticPuffins (Fratercula arctica). Here we estimated the mortality of alcids in Galicia (northwestern Spain), thearea that received most of the Prestige oil and where half of the oiled seabirds were collected. We performedthree experiments that included: (1) a test of several drift block models in open sea, to select the one thatbest fitted the drift of alcid carcasses; (2) the release of 450 drift blocks at 9 offshore points to assess therecovery rate of oiled alcids and its spatial variation; (3) the assessment of beach survey effort and thedetectability of drift blocks. Mean mortality estimates and their bootstrapped confidence intervals wereobtained through an estimation model that established: (1) a temporal limit of 23 days to block drifting; (2)spatial differences in the recovery rates of blocks depending on how far away from the coast they werereleased; (3) a correction factor accounting for detectability, and (4) the distribution pattern of the threealcid species involved according to three distance classes, based on ship surveys. The Prestige oil spill, interms of acute seabird mortality, was one of the worst oil spills ever reported worldwide. Compared toother major oil spills the estimated mortality for the Prestige oil spill was higher than expected from thenumber of carcasses retrieved. We recommend that drift block assessments of seabird mortality should beincluded in contingency response plans to oil pollution emergencies; therefore, a supply of drift-blocksdesigned to mimic the drifting behavior of the marine bird species of interests should be at hand
