Resumen

Heavy metals are a threat to wildlife, and they have yet to be analyzed in seabirds from the Galápagos Archipelago. To gauge their prevalence in Galápagos seabird species, we collected and analyzed feather samples from Galapagos Penguins Spheniscus mendiculus, Flightless Cormorants Phalacrocorax harrisi, and Waved Albatross Phoebastria irrorata in seven different breeding areas in 2011 and 2012 as part of an ongoing mark-recapture study. The results showed that lead is higher in penguins and cormorants; cadmium was found to be below the limit for quantification in all our samples. The heavy metals recorded did not have a clear local source related to human activities, as breeding areas are not located near populated areas. Environmental media (soil, water), marine currents, and atmospheric deposition are possible sources.
