Guests will be seeing double when they visit Brookfield Zoo’s Pinniped Point in a few weeks. Two California Sea Lion pups were recently born, and they are the first of this species born at the zoo in nearly 30 years.
The new pups are currently behind the scenes, bonding with their mothers, and learning how to swim, as well as being monitored by animal care staff. It is anticipated the pups will have access to their outdoor habitat in a few weeks.
The first pup, a female, was born on June 4 to seven-year-old Josephine. A week later, on June 11, Arie, who is estimated to be about nine-years-old, gave birth to a male.
California Sea Lion pups are usually born in June and July and will weigh between 13 to 20 pounds. Pups do not swim for their first few weeks of life, but rather stay in tidal pools until they can go to sea with their mothers. They nurse for at least five months and sometimes for more than a year. In the wild, after giving birth, mother Sea Lions will leave their offspring for a short time while they forage at sea. As the pups grow stronger, the mothers leave them alone for longer periods. Mother Sea Lions recognize their pups through smell, sight, and vocalizations.
The new additions at Brookfield Zoo are very important to the genetic diversity of the accredited North American zoo population for the species because of the unique backgrounds of the two moms as well as of Tanner, the pups’ sire. All three adults were wild born and deemed non-releasable by the government for various reasons. All were taken in and given homes at three accredited facilities: Aquarium of Niagara, Brookfield Zoo, and Shedd Aquarium.
“We couldn’t be more thrilled with the birth of these two Sea Lion pups, which is a coordinated effort between us and our partner facilities,” said Rita Stacey, Curator of Marine Mammals for CZS.
