  abstract = {{U}nderstanding the factors that drive the dynamics of populations of long-lived species presents a unique challenge for conservation management. {H}ere, we investigated long-term change in the body condition of adult northern rockhopper penguins {E}udyptes moseleyi at {A}msterdam {I}sland, southern {I}ndian {O}cean, which hosts 5-10% of the global population of this endangered species. {A}nalysis of a long-term dataset (1994-2016), concurrent to the population's rapid decline, revealed no trend in adult northern rockhopper penguin body condition over time at the stages considered in this study, i.e. breeding and moulting. {H}owever, body condition varied between years and sexes and part of this variation was explained by environmental factors. {M}ales were on average in better condition than females whatever the stage and individuals on average were in better condition during the moulting compared to the breeding period. {T}he environmental conditions [sea surface temperature anomaly ({SST}a), {S}ubtropical {I}ndian {O}cean {D}ipole ({SIOD}) and {S}outhern {A}nnular {M}ode ({SAM})] appeared to impact non-linearly the body condition. {O}verall, females were in better condition for negative values of {SAM}, {SIOD} and {SST}a. {T}he body condition of males exhibited similar but less complex and more significant patterns, with decreasing body condition for increasing {SAM}, {SIOD} and {SST}a. {T}he absence of long-term trends in male and female body condition suggests that the very low reproductive output and declining population since 1997 is probably not the result of environmental conditions during pre-breeding and pre-moult and necessitates further research into possible drivers during the breeding season.},
