Fry, D M

The objective of the study was to investigate short- and long-term effects of oil exposure on three species of seabirds: Cassin's Auklet (Ptychoramphus aleuticus), Common Murre (Uria aalge), and Wedge-tailed shearwater (Puffinus pacificus). Field studies with auklets were carried out on Southeast Farallon Island (SEFI), 40 km west of San Francisco, using 500 artificial nesting burrows. Cassin's Aulkets were dosed with 1 ml weathered oil either orally by gelatin capsule or externally by application to the breast plumage. The data strongly support the hypothesis that breeding failure after oil exposure resulted in mate switching which caused overall lowered breeding success in both Cassin's Auklets and Wedge-tailed shearwaters.
