Injured Resources Addressed: Black Oystercatchers

Abstract: This study was divided into two parts. The first part was to estimate the number of spring migrant shorebirds using oilaffected portions of the Prince William Sound. Objectives included: estimate the amount of time shorebirds are exposed and number of shorebirds of each species exposed to contaminated beaches; estimate proportion of migrants contaminated; test for differences in feeding behavior; collect tissue samples for analysis and identify contamination pathways in the food chain; and determine nesting success of black turnstones. Part two of the study dealt with black oystercatchers. The objectives of this research were to: 1) determine the effects of oiling on the reproductive success of oystercatchers; 2) determine habitat requirements of breeding oystercatchers; and 3) explore how the feeding strategy of oystercatchers may affect populations of invertebrate prey species.
