Pregnant females also begin arriving in December, giving birth within days of landing on the beach. Don’t forget your binoculars and a hooded jacket because it’s often very cool and windy. Adult males are fighting over dominance over pupping areas and usually the first birth is mid-month. In January, females continue to arrive, with birth numbers peaking in the last half of the month.

What Is a Rookery of Seals?

A typical rookery of seals consists of a small to large colony of seals. The actual word rookery refers to the nesting place of breeding animals like seabirds or marine animals like the elephant seal. Typically a rookery is where the elephant seal was born. So for example, if an elephant seal was born at the Piedras Lighthouse, they will return here next year after they leave to eat food near the gulf of Alaska.

Do Elephant Seals Have Any Predators?

In the ocean, elephant seals are at the top of the food chain because of their size and tusks. However there are a few predators that are known to attack elephant seals: killer whales and white sharks. Elephant seals use their size and tusks to protect themselves from these large predators and they are also really loud which helps to scare away other predators.

Birthing and Breeding Season

The majority of the birthing season is from early Winter and lasts until Spring. Typically the female elephant seals are arriving to the rookery to give birth and once arriving on land, within a couple of days births will happen. Interesting enough, the typical newborn seals are born at night and weigh around 50 pounds up to 280 pounds. After the newborn seal is birthed, the mother will stay and nurse the young seal for almost a month (around 25 days). After nursing the young seal and getting him or her up to speed the mother elephant seal will mate with the alpha elephant seal (called a "bull"). After she mates the alpha elephant bull, the mother will say goodbye to the young seal and go back to the sea. The young elephant seal will learn to swim and find food by himself. This is a process which many young seals will learn the "ropes" and once they are ready to take the plunge into the ocean, they take off into the sea around late April.

Molting Season

If you are wondering when the molting season for elephant seals we have you covered. The molting season for elephant seals typically starts in April and lasts till about the end of May (4-6 weeks). Most of the females and smaller juvenile elephant seals molt on the shore. Typically each elephant seal will stay on land until the molting in complete and then they will go back in the water once completed. Most the adults and juveniles are done with molting by the very end of May and are happily back in the water splashing around. If you are wondering if males molt, the answer is yes. In June, the males and "teenager" males go back to the rookery and start their molting process. Typically by August most the adults and teenage male are done with molting. During this period (August), is when you will see the least amount of seals in the rookery.

Background of Elephant Seals

Not many people know that at one point elephant seals were hunted to near extinction. The reason was because whales were becoming scarce and fishermen needed an alternative source for blubber. Because of this, fishermen turned to hunting elephant seals instead of whales. By the early 1900's there were an estimated 100 elephant seals left in the entire world. It was estimated that all 100 of those elephant seals were found off the coast of Baja California in Mexico. The story does have a happy ending. Mexico declared the elephant seal an endangered species and provided them with safe haven. To date, approximate population of elephant seals is over 150,000 with the great majority of the elephant seals near California waters. That is why we're seeing so many elephant seals at the Piedras Blancas Elephant Seal Rookery. We should consider ourselves lucky that we're able to see the elephant seals and especially in such close driving distance for those near the California central coast.
