Abstract

Gadfly petrels (Pterodroma spp.) are one of the most threatened and poorly studied seabird groups, and as marine predators, areexposed to biomagnified and bioaccumulated chemical pollutants from their prey.We quantified trace element concentrations inbreast feathers of seven petrel species that breed in the southern hemisphere to quantify current concentrations. Selenium (Se)concentrations were significantly lower in chicks than adults; this was not observed for zinc (Zn) or lead (Pb). Overall, the speciesexamined here exhibited similar concentrations of Se, with Pb and Zn concentrations more variable among species. The mean Seconcentration in adult birds exceeded those thought to be potentially deleterious, and three species had concentrations that wereabove the assumed threshold for Pb toxicity. Further investigation of potentially toxic trace elements in gadfly petrels iswarranted.
