In otariids, mother–pup pairs are frequently separated during lactation, pups are highly mobile at an early stage, and the high densities of colonies increase the risks of confusion between individuals. Accordingly, vocal recognition between mothers and pups is well developed in this group.

We performed playback experiments on 18 breeding female harbour seals to assess their abilities to recognize the calls of their pup and to evaluate the effect of maternal protectiveness and pup vocal stereotypy on the recognition process. In addition, we performed propagation tests to assess pup call propagation efficiency in the environment. As early as 3 days after birth, females were more responsive to calls of their own pup than to calls of nonfilial pups. Female responses also varied depending on their protective behaviour displayed towards their pup. Vocal discrimination abilities were positively correlated with the level of individuality conveyed in pup calls. Considerable differences in the propagation efficiency of pup calls were measured among sites used for mother–pup reunions. This study provides experimental evidence that wild harbour seal females recognize the calls of their pup among others, and that they memorize previous versions of their pup's calls, taking into account age- and size-related effects on vocalizations. Propagation tests further suggest that some mother–pup reunion sites are better suited for vocal recognition than others.

International audience Mother–pup vocal recognition abilities in pinnipeds reflect maternal reproductive strategies.
