The Pittsburgh Zoo & PPG Aquarium is celebrating the birth of a new sea lion pup!
Maggie gave birth to one pup Sunday night at approximately 9:45 p.m. Keepers noticed a change in Maggie’s behavior last Friday.
“She wasn’t eating. She really didn’t want to swim and was keeping to herself most of the day,” says Judy Obeldobel, sea lion keeper. “We knew that she would deliver this weekend.”
The mortality rate of sea lions is 10 to 15 percent in the first month, so keepers and medical staff will keep a close eye on the two.
“We are all very excited and happy for Maggie,” says Henry Kacprzyk, curator of Kids Kingdom. “Both mom and pup appear to be doing very well. They are communicating and the pup is nursing, which are the two most important indicators of good health. The fact that Maggie witnessed and participated in the development of another pup for the last 16 months, will help her be a good mom as well.”
This is Maggie’s first pup and the second pup born in the history of the Pittsburgh Zoo & PPG Aquarium.
Maggie delivered her baby near the keeper door to the outside pool deck and is being very protective of her baby. “We can’t even open the keeper door because Maggie is keeping everyone away,” says Ms. Obeldobel. “Especially Summer and Sidney (Zoey’s 16 month-old pup) who are very curious and want to have a look, but Maggie chases them right back into the water.”
Once Maggie is comfortable, keepers and the vet staff will exam, weigh, and determine the sex of the baby. We will not interfere unless we suspect that the baby isn’t nursing or if it stops communicating with mom. The next big challenge for the pup is when Maggie begins the first swimming lessons in a couple of weeks.
Sea lions normal total gestation is eleven months, which can include a delayed implantation of an additional two to three months. Pups are generally born in the summer when food is more plentiful. Delayed implantation is when the embryo remains in a state of dormancy before it begins to develop. “Because September is a late birth, we are being sure to provide enough warmth for mom and pup,” says Mr. Kacprzyk. Keepers have placed overhead and radiant heaters safely nearby.
Sea lions normally give birth to one pup, but on rare occasions, twins have been born. Sea lion pups are born dark brown to black, but will fade to light brown within a couple of weeks. At birth they are well-developed and can move, scratch, and groom themselves. Swimming will occur when the pup is a couple of weeks old.

Regarding the naming of the new baby sea lion.
I think you should call her Aubrey Rose. The same day she was born my Aubrey Rose and I and her two aunts Sandy and Shannon were at the zoo for Aubrey’s 1st time there and she fell and cut her lips, they were bleeding alot and they swelled up really fast. Luckily a man asked if we wanted him to call someone and also there was a nurse walking by and she looked at Aubrey and then the ems guys were there in minutes and gave us an ice pack and water and gauze and he said she didn’t look like she needed stitches. Aubrey ended up ok and forgetting about her poor lips and she enjoyed the rest of her 1st Zoo visit. Of course she fell fast asleep as soon as we put her in her car seat, she was all tuckered out
Thank you,
Donna Rupinski and Aubrey Rose Rupinski.
