Pacific Harbor Seals - Pupping Season on the Oregon Coast
Generally on the Oregon Coast, the annual seal pupping season occurs during a time period from March thru June. Usually, pregnant females give birth to a single pup on land within the months of March thru May. The mother nurses the young pup for up to six weeks on a high fat content milk diet before weaning the pup for its own survival. During this cycle, the young pups can be observed hanging close to its mother, nursing every three or four hours. Seal pups are born well-developed with their eyes open and having an ability to swim right away. Seal pups weigh up to 25 pounds at birth and over their nursing period, they more than double in size. Seal pups and their mothers maintain a close relationship until after the weaning period, when the mother sheds any future interest in the pup. During the nursing period, the mother will leave the seal pup unattended as she forages for food and will utilize both vocalization and a sense of smell to relocate her own pup. The breeding season occurs about six weeks after the pupping season when individual males mate with several females in heat, usually in late springtime and early fall.
