  abstract = {{B}ackground: {C}limate-driven environmental change in the {N}orth {P}acific has been well documented, with marked effects on the habitat and foraging behavior of marine predators. {H}owever, the mechanistic linkages connecting climate-driven changes in behavior to predator populations are not well understood. {W}e evaluated the effects of climate-driven environmental variability on the reproductive success and foraging behavior of {L}aysan and {B}lack-footed albatrosses breeding in the {N}orthwest {H}awaiian {I}slands during both brooding and incubating periods. {W}e assessed foraging trip metrics and reproductive success using data collected from 2002-2012 and 1981-2012, respectively, relative to variability in the location of the {T}ransition {Z}one {C}hlorophyll {F}ront ({TZCF}, an important foraging region for albatrosses), sea surface temperature ({SST}), {M}ultivariate {ENSO} {I}ndex ({MEI}), and the {N}orth {P}acific {G}yre {O}scillation index ({NPGO}). {R}esults: {F}oraging behavior for both species was influenced by climatic and oceanographic factors. {W}hile brooding chicks, both species traveled farther during {L}a {N}ina conditions, when {NPGO} was high and when the {TZCF} was farther north (farther from the breeding site). {M}odels showed that reproductive success for both species showed similar trends, correlating negatively with conditions observed during {L}a {N}ina events (low {MEI}, high {SST}, high {NPGO}, increased distance to {TZCF}), but models for {L}aysan albatrosses explained a higher proportion of the variation. {S}patial correlations of {L}aysan albatross reproductive success and {SST} anomalies highlighted strong negative correlations (> 95 %) between habitat use and {SST}. {H}igher trip distance and/or duration during brooding were associated with decreased reproductive success. {C}onclusions: {O}ur findings suggest that during adverse conditions ({L}a {N}ina conditions, high {NPGO}, northward displacement of the {TZCF}), both {L}aysan and {B}lack-footed albatrosses took longer foraging trips and/ or traveled farther during brooding, likely resulting in a lower reproductive success due to increased energetic costs. {O}ur results link climate variability with both albatross behavior and reproductive success, information that is critical for predicting how albatross populations will respond to future climate change.},
