International audienceBegging signals from the young are used to elicit parental care. Although honest and parent-directed signalling seems to be widely shared characteristic of begging behaviour, offspring might modify their strategy under some ecological or environmental constraints. In the subantarctic fur seal, Arctocephalus tropicalis, mothers forage at sea for 23 weeks at a time throughout the lactation period, resulting in regular separations of mothers and pups. Using playback experiments we investigated modifications of pups' begging behaviour during their mother's absence. From the 1st to the 5th day of maternal absence, pups rarely begged in response to other adult females' vocalizations (17.646.7% of tested pups), but always res...
