  abstract = {{T}he {B}lack {N}oddy ({A}nous minutus) and the {B}rown {N}oddy ({A}. stolidus) occur sympatrically in the {S}outhern {L}agoon of {N}ew {C}aledonia, breeding on islets located at the edge of a wide, productive coral-reef lagoon next to oceanic waters enriched by a seasonal upwelling. {T}he diets of the two species were determined from regurgitations from birds nesting at {K}ouare {I}slet during two consecutive breeding seasons (2002/2003 and 2003/2004) and compared. {T}he average prey load in the {B}rown {N}oddy was heavier than that in the {B}lack {N}oddy, as expected from its larger body size and from a predicted longer foraging distance. {F}ish prey dominated the diet of both species (100% and 81.8% biomass in {B}lack and {B}rown {N}oddies, respectively); the remainder consisted of squid. {B}lack {N}oddy ate small pelagic fishes inhabiting the reef and the lagoon, mainly round herrings ({S}pratelloides spp.), and {B}rown {N}oddy mainly preyed on offshore species including buccaneer anchovy ({E}ncrasicholina punctifer) and larger pelagic fishes ({E}xocoetidae) and squids. {T}he segregation in diet between {B}lack and {B}rown {N}oddies in {N}ew {C}aledonia thus indicated spatial segregation in foraging zones (i.e., inshore versus offshore, respectively), which was more pronounced than previously reported for other sites where the two species co-occur.},
