International audience The Southern Fulmar, Fulmarus glacialoides, is an ice-dependentseabird, and individuals forage near the ice edge. During an extremeunfavorable sea ice year (ESIC), foraging trips were greater in distanceand duration, adults brought less food to their chicks, which fledgedin the poorest body condition. During such ESICs, breeding successwas extremely low; hence the population growth rate was greatlyreduced. Some individuals coped better with ESICs, which tend toexacerbate individual differences in intrinsic quality. Finally, changes inthe frequency of ESIC have a strong impact on the persistence ofSouthern Fulmar populations.
