Seal Sitters sends out warm flipper hugs to those most special souls - mothers! Happy Mother’s Day to our human moms - thanks for all your nurturing, guidance and support.

This day is a reminder, too, that spring is the time for birthing of many wildlife species. Seals and sea lions are now being born along the Pacific coastline. Share the Shore - stay back and do not disturb! To view a map which show the pupping season timeline in Oregon and Washington, click here.

Harbor seal moms form affectionate bonds with their pups. Immediately after birth (see birth photos here), a mom must memorize the scent and call of her newborn so she can locate the pup if they are separated. Pups weigh between 18-30 lbs when born. Mom will nurse her pup for 4-6 weeks and then the chubby pup is on his own - now gaunt from nourishing her pup, she needs to replenish her own fat stores. During that short time, she must teach her pup all the skills to survive against daunting odds - only 50% of pups survive the first year.

Pups can swim within minutes of birth (hours-old pup shown swimming with mom in photos). A 2-day-old pup can stay underwater for 2 minutes. Like small human children, they will rest on mom’s back when tired and hitch a ride. Most times, the pup accompanies mom on foraging trips to learn how to hunt. He will learn that patience pays off when foraging. SeaDoc Society studied the differing foraging patterns of wild weaned seal pups versus rehabilitated pups who had no mom to teach them life lessons. The scientists found that rehab pups travelled much further in search of food, wasting essential calories.

Sometimes, a mom will leave her pup, who may not be strong enough to forage for hours, alone to rest on shore. She returns later to nourish her hungry pup. Always stay back from a resting pup. Otherwise, the mom may abandon her young due to human interference.

And finally, a “shout-out” to our Seal Sitters volunteers who are moms. These great women teach their children that respect for wildlife and concern for the health of our waterways is an empowering lesson to be learned and shared with others. We cannot thank you enough.
