  abstract = {{T}wo species breeding in sympatry are more likely to coexist if their ecological niches are segregated either in time, space or in trophic habits. {H}ere, we combined {GPS}-tracking, stable isotope analysis and {DNA} metabarcoding analysis to understand how the rare {T}ahiti petrel {P}seudobulweria rostrata ({TP}) copes with the very abundant (i.e. 500,000 breeding pairs) wedge-tailed shearwater {A}rdenna pacifica ({WTS}) when breeding in sympatry in a tropical area. {WTS} foraged in restricted areas along their path, while {TP} predominantly foraged using extensive search behavior, suggesting a more opportunistic foraging strategy. {I}nterspecific overlap of foraging areas was higher than intraspecific overlap. {B}reeding seasons largely overlap between species during the study, but {TP} seems to be asynchronous breeders. {TP} fed upon prey with higher delta {N}-15 values than {WTS}, and their diet was mainly composed of deep-sea organisms. {TP} could feed upon dead prey floating at the surface while {WTS} preyed mainly upon fish species that generally move in schools. {O}ur study highlights several segregating mechanisms (temporal, behavioral and trophic) that could facilitate the coexistence of the two species despite the predominant number of {WTS}, and provides the very first information on the foraging and trophic ecology of the poorly-known {TP}.},
