  abstract = {{T}he {Y}elkouan {S}hearwater {P}uffin us yelkouan is a {P}rocellariiform endemic to the {M}editerranean {B}asin, recently categorised as {N}ear {T}hreatened on the {IUCN} {R}ed {L}ist. {W}e need to identify the threats it faces, which are particularly poorly understood when at sea. {S}pecifically, very little is known about the {Y}elkouan {S}hearwater feeding strategy and how it is related to potential threats at sea, such as contaminants which deserve particular attention regarding this shearwater, as the {M}editerranean {B}asin is overall highly contaminated. {H}ere, we analysed {Y}elkouan {S}hearwater diet, as well as metal (lead, cadmium, mercury, selenium) and organic contamination. {T}he diet analysis revealed the predominance of fish prey, particularly {C}lupeids, {E}ngraulids and {S}combrids, both in terms of relative occurrence (84.6%) and relative biomass (99.7%). {C}rustaceans ({E}uphasiacea and {D}ecapoda) were the major prey type during the pre-laying period (relative number: 88.8%) but contributed little to the biomass ingested. {T}he metal levels we found in contour feathers were below the known adverse effect threshold for seabirds. {O}rganic contamination in livers was also low but we found two eggs with levels of concern of polychlorinated biphenyls ({PCB}) and dichloro-diphenyl-trichloroethane ({DDT}) compounds.},
