*Early onset of postnatal individual vocal recognition in a highly
colonial mammal species *
Mathilde Martin, Tess Gridley, Simon Elwen, Isabelle Charrier
Abstract:
Mother–young vocal recognition is widespread in mammals. The features of
vocal recognition are known to be shaped by the ecological constraints
faced by each species. In some species, a rapid establishment of
mother–young vocal recognition is crucial for offspring’s survival.
However, knowledge of the precise features of this recognition system,
especially the timing of the onset in the first hours after birth, is
often lacking. Here we show that Cape fur seal females can recognize
their pup’s voice 2–4 h after parturition and that pups develop this
aptitude 4–6 h after birth. This study is the first to investigate this
mechanism in a wild and free-ranging mammal from only 2 h after birth.
We report the fastest establishment of mother–young vocal recognition
for any mammalian species, including humans, described to date. Such
early vocal identification in pups suggests an in utero vocal
imprinting. These findings highlight the synergistic role of
environmental constraints and biological traits in optimizing the timing
of individual vocal recognition onset in vertebrates.
