Etude, chez Zalophus californianus, de la reponse des jeunes a l'appel des meres lors des reunions et du role des jeunes et de la mere pendant ces reunions 
Individual variation in nursing vocalizations of Hawaiian monk seal pups, Monachus schauinslandi (Phocidae, Pinnipedia), and lack of maternal recognition
Vocalizations of individual Hawaiian monk seal pups, Monachus schauinslandi, do not have unique attributes that enable females to recognize their own offspring. Despite low aggregation density duri...
A study into the mother–pup relationship in three California sea lion Zalophus californianus mothers and pups at Barcelona Zoo
The limited number of studies into maternal care in captivity carried out on California sea lions Zalophus californianus indicates that it is necessary to study their biology and behaviour in greater
BEHAVIORAL CUES USED IN REUNIONS BETWEEN MOTHER AND PUP SOUTH AMERICAN FUR SEALS (ARCTOCEPHALUS AUSTRALIS)
TLDR
The best predictor of search success was pup response: after pups called and moved toward mothers, pairs were reunited 95% of the time regardless of mothers’ behavior, suggesting that pups’ acceptance criteria are conservative when risk of injury from unrelated females is high.
Mother–offspring reunion in the South American sea lion Otaria flavescens at Isla de Lobos (Uruguay): use of spatial, acoustic and olfactory cues
TLDR
The results support the hypotheses that mother–pup dyads combine spatial, acoustic and olfactory cues for successful recognition and reunion behaviour and that pups play an active role in the process.
Delayed onset of vocal recognition in Australian sea lion pups (Neophoca cinerea)
TLDR
Variance in colony density, pup movements, and natal site fidelity may have reduced selective pressures on call recognition in young sea lions, or alternatively, another sensory system may be used for recognition in the early stage of life.
Mother - pup reunions in harp seals, Phoca groenlandica: cues for the relocation of pups
TLDR
This study was designed to examine how female harp seals solve the orientation problems they face when returning to their pups from the water in a pack-ice environment.
Aggregation and dispersion of female New Zealand sea lions at the Sandy Bay breeding colony, Auckland Islands: How unusual is their spatial behaviour?
TLDR
Females that had to move more during the pupping day were found to be more likely to lose their pups, and a larger population size during one year may have created a dilution of male aggressiveness and resulted in fewer movements of females.
How mothers find their pups in a colony of Antarctic fur seals
TLDR
Investigating the means by which female Antarctic fur seals identified their pups in a breeding colony of about 750 mother-pup pairs suggests that finding pups is a two-stage process for females, in which pups for sampling are attracted by calls or examined at the previous nursing location, and then individual identification is made by olfactory cues.
Individuality in harp seal, Phoca groenlandica, pup vocalizations
TLDR
Alongside vision and smell, acoustic cues appear to be important in relocating offspring in gregarious breeders and differences in vocal variability between sexes may reflect different selection pressures working on males and females.
Vocal development in captive harbor seal pups, Phoca vitulina richardii: age, sex, and individual differences.
TLDR
Calls were individually distinctive even in pups less than 2 weeks old, suggesting that mothers may be able to recognize pup vocalizations at this early age, and supporting the theory that recognition is more highly developed in otariids.

TLDR
The analysis of the PACs of mothers and the bleats of pups shows that interindividual variability of calls provides a sufficient basis for individual recognition in both species.
