Trace Element Concentrations in Feathers of Seven Petrels

Gadfly petrels (Pterodroma spp.) are one of the most threatened and poorly studied seabird groups, and as marine predators, are exposed to biomagnified and bioaccumulated chemical pollutants from their prey. We quantified trace element concentrations in breast feathers of seven petrel species that breed in the southern hemisphere to quantify current concentrations.

Ingested plastic as a route for trace metals in Laysan Albatross (Phoebastria immutabilis) and Bonin Petrel (Pterodroma hypoleuca) from Midway Atoll

Between 25 and 100% of Laysan Albatross and Bonin Petrel fledglings from Midway Atoll sampled in 2012 exceed international targets for plastic ingestion by seabirds. High levels of plastic were correlated with increased concentrations of chlorine, iron, lead, manganese, and rubidium in feathers.
