Seal pups recognize mother's voices within days of birth

Seal pups can recognize their mother's distinct vocal call within two days of birth says a University of Alberta researcher--a finding essential to the pups' care and survival. Dr. Isabelle Charrier, from the U of A's Faculty of Science, has extensively studied how mothers and seal pups use vocal recognition to identify each other. Her findings are published in the current issue of the international journal, Animal Behaviour.

Charrier spent nine months on Amsterdam Island in the Indian Ocean, studying and recording acoustic recognition between the female and her pups. When these fur seals come ashore to breed in dense colonies, the lactating females must leave their newborn pups on land while they forage for food at sea. As with most social species, the fur pups only feed their own offspring so when the mother returns from sea, it is essential for the mother and pup to find each other among the several hundred other mammals.

"We found out that pups can recognize their mother's call within two to five days after birth," said Charrier. "This is surprisingly quick but considering that the mother leaves seven days after giving birth it is important to have that immediate recognition."

During her time on Amsterdam Island, Charrier recorded the signals and then modified them to determine which parts of the acoustic parameters support the recognition process. When a mother returns from a foraging trip, she is confronted with both acoustic jamming and a high risk of visual confusion and finding her pup under such conditions should be difficult. Yet Charrier learned that upon return, mothers and pups can recognize each other with seven minutes of the initial call.

If a mother was gone a particularly long time--they can be away for up to three weeks--the pup would become so hungry, it would try to respond to another female's call in an attempt to be fed. But mothers are quick to dismiss and even become aggressive to pups other than their own.
