Welcome, Winter!
The First Pup of the Piedras Blancas elephant sealbreeding season
The first elephant seal pup of the breeding season
appeared on the south beach of the Piedras Blancas viewpoint on Sunday morning,
December 8. Sharp-eyed Kris Clifford noticed the pup on the Friends of the
Elephant Seal webcam. https://elephantseal.org/
Mother and pup are resting comfortably on the beach. A
substantial bull stood guard some distance away. He bellowed frequently Monday
afternoon. A few other bulls slept on the beach in the area, presumably aware
of the newcomer and its mother.

Naming rights
FES Docent Bill Michelson named the pup Winter. He had
the privilege of naming because he won the First Pup contest. It’s an informal
lottery, to guess the date when the first pup will arrive. Michelson won,
earning the naming privilege and bragging rights for the season.
Harbinger of the season
Winter is the first of over 5,000 pups that will be
born between now and February at the Piedras Blancas rookery, which extends
from the light station to about a mile south of the viewpoint. Mothers will
continue to arrive, one by one. They settle on the beach for a few days and
then give birth to their pups.
Seeing a pup born is exciting. Many pups are born at
night, as Winter may have been, but daytime births are common.
Look for a female seal digging out a “saddle” by
tossing a lot of sand on both sides. That sometimes indicates that she will
soon give birth.
Nothing is certain, though. As soon as you’re paying
attention to one seal, another down the beach will squirt out a pup.
Gull announcements
As soon as a pup is born, gulls screetch and swoop
around to consume the afterbirth. They are the beach clean-up crew. If you miss
seeing the moment of birth, you can follow them to see the newborn and mother
make their first barks and sniffs to each other.
Pups and their mothers recognize each other by their
vocalizations and their scent. That gets established within the first couple of
days of life. It’s important, because a pup separated from its mother may
starve and die. Maternal separation is the most common cause of pup death.
While all pups are vulnerable, most pups nurse on more
than one mother at some time. Later, when the beach is crowded with mothers and
pups, some mothers may nurse more than one pup.
Not every pup survives, although over 90 percent of
the pups at Piedras Blancas do. A mother whose pup dies may let other pups
nurse, or may adopt another pup.
One pup per mother
Each mother has only a single pup, about three feet
long and weighing about 75 pounds. Mothers nurse the pups for about a month.
They pup gains weight rapidly, up to about 300 pounds. The mothers stay with
the pup the entire time. They don’t leave the pup to feed in the ocean, so they
lose a lot of weight, about a third of their body weight.
It’s good to see Winter’s mother looking fat. She’ll
need it.
Winter is in a good position on the beach, well above
high tide line. That’s an important consideration, because King Tides, the
highest tides of the year, will reach up the beach this weekend, December
13-15.
Winter can’t swim much yet, and hasn’t nursed long
enough to gain much blubber. Without blubber to stay warm, and able only to
paddle a little in the water, pups can drown.
Mothers may give birth at low tide, not realizing that
their pups may be at risk later. Most of the north beach at the Piedras Blancas
viewpoint is inundated with waves at high tide. Some pups born in the few areas
behind rocks are safe, but any born on the open sand may be washed away.

Share King Tide photos
You can take photos and submit them to the California
King Tides Project. Think about taking photos in areas that
are subject to flooding and erosion, and of places where high water levels can
be gauged against familiar landmarks such as cliffs, rocks, roads, buildings,
bridge supports, sea walls, staircases, and piers.
Taking and sharing photos documents the changes in
ocean level and how those changes are affecting the coastline.
