  abstract = {{T}ropical insular ecosystems face escalating, cumulative impacts of land- and sea-based ecological threats that jeopardize the long-term sustainability of their native communities. {T}his joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey availability, human disturbance, and predation by invasive non-native species. {U}sing site monitoring data acquired from 2000 to 2023, we investigated drivers of species presence and abundance for 15 seabird species (nine {L}aridae, three {S}ulidae, two {F}regatidae, and one {P}rocellariidae) on 100 coral reef islands around {N}ew {C}aledonia, {S}outh {P}acific. {W}e established presence and abundance estimates using a compendium of 2805 observations and tested the relative influence of onsite breeding habitat area, characteristics of neighboring marine environments, human visitation, and rodent presence. {R}esponses to ecological drivers varied across species and highlighted distinct functional and taxonomic groups. {T}he presence and abundance of pelagic-feeding species with high site fidelity were predominantly determined by the availability of breeding habitat, whereas the presence of coastal foragers, including most gulls and terns, appeared constrained by resource availability near breeding sites. {H}uman disturbance had a significant negative influence on the presence of brown noddy ({A}nous stolidus; [-3.41; -1.20]), masked ({S}ula dactylatra; [-3.85; -1.21]), and brown ({S}ula leucogaster; [-4.57; -1.46]) and red-footed booby ({S}ula sula; [-9.58; -1.20]) and a significant positive influence on the abundance of the commensal silver gull ({L}arus novaehollandiae; [0.03; 0.09]). {O}ur results emphasize the importance of habitat restoration and mitigation of human disturbance for preserving breeding sites of pelagic-feeding species. {H}owever, it may be difficult to sustain populations of coastal seabirds whose presence is mostly driven by small-scale prey distribution. {T}hus, a comprehensive approach that fully considers the functional diversity of target seabird communities is needed.},
