Abstract: This study will directly document the exposure of black oystercatchers to oil remaining in the mussel beds and fine sediments of Prince William Sound after the EVOS.
Exposure to oil will be documented by observing where birds forage and what they eat and by analyzing the feces of chicks for hydrocarbon contamination. The survival of chicks raised in the spill area, and recruitment of breeders into the spill area populations will be documented.
Black oystercatchers do not avoid feeding in or delivering prey to chicks from persistently oiled substrates. Despite being fed more biomass, chicks raised at persistently oiled nest sites grow slower than chicks at unoiled nest sites. Females renesting at oiled sites produce fewer eggs of lesser volume than females renesting at unoiled sites.
