Effects of the Exxon Valdez oil spill on migrant shorebirds using rocky intertidal habitats of Prince William Sound, Alaska, during spring 1989

Metadata Updated: December 11, 2019

A minimum of a few 10, COO's of surfbirds (Aphriza virgata) and black turnstones (Arenaria melanocephala) used rocky intertidal habitats of southwestern Prince William sound in spring of 1989. Virtually all of the shorebirds were found using shorelines, primarily on northern Montague Island, subjectively classified in the field as lightly oiled or unoiled. Heavily oiled areas were probably little used in 1989, thus the proportion ofbirds directly contaminated by oil on plumage, while unknown, was probably small. Surfbirds and black turnstones preyed mainly on herring eggs, blue mussels, and barnacles. Samples of these prey items from oiled areas contained petroleum-derived hydrocarbons, as did at some of the samples from the relatively clean portions of Montague Island. The results of chemical analysis of a small sample of shorebird liver tissues provided only limited support for the hypothesis that shorebirds had ingested significant quantities of petroleum-derived hydrocarbons. Clutch sizes of black turnstones on the Yukon-Kuskokwim delta breeding grounds, in western Alaska, were reduced relative to prespill years, but no direct link can be drawn to the spill. Surfbirds and black turnstones probably escaped significant population impacts as a result of the EVOS because shorelines which received heavy use by these species were largely spared contamination.
