  abstract = {{A}ssessing mercury ({H}g) biomagnification requires the description of prey-predator relationships, for each species and ecosystem, usually based on carbon and nitrogen isotope analyses. {H}ere, we analyzed two seabirds from the {H}umboldt {C}urrent ecosystem, the {G}uanay cormorant ({P}halacrocorax bougainvillii) and the {P}eruvian booby ({S}ula variegata), as well as their main prey, the {P}eruvian anchovy ({E}ngraulis ringens). {W}e reported {H}g concentrations, {H}g biomagnification ({BMF}) and isotopic discrimination factors (delta {C}-13 and delta {N}-15) in seabird whole blood. {BMF}s and delta {C}-13 in our study (on wild birds where diet was not controlled) were similar to other piscivorous seabirds previously studied in captive settings, but delta {N}-15 were lower than most captive experiments. {W}e observed lower {H}g concentrations in {H}umboldt seabirds compared to other oligotrophic ecosystems, possibly due to {H}g biodilution in the high biomass of the first trophic levels. {T}his work calls for a better characterization of {H}g trophic dynamics in productive upwelling ecosystems.},
