CHICAGO — In a moment filled with teamwork and instinct, a 38-year-old dolphin named Allie gave birth to a healthy calf at Brookfield Zoo early Saturday morning — and the birth was not only captured on video, but also assisted by a fellow dolphin mom.
The dramatic and joyful moment unfolded as Tapeko, a 43-year-old experienced mother dolphin, swam alongside Allie during labor, helping guide the newborn calf to its first breath at the water’s surface.
“Push, push, push,” a staffer can be heard cheering in the background as Allie labored in the Seven Seas exhibit, according to FOX 5 San Diego.
Teamwork in the Tank
As Allie swam in circles, the calf’s tail was visible — and within moments, it wriggled free and instinctively darted to the surface. Tapeko closely followed, helping ensure the calf got its first critical breath.
Veterinarians say it’s common for dolphins to assist one another during birth in both wild and aquarium settings.
“It provides the mom extra protection and help to get the calf to the surface,” said Dr. Jennifer Langan, Senior Veterinarian at Brookfield Zoo.
Calf’s Early Health Signs Look Good
The newborn dolphin is estimated to weigh 35 pounds and measure nearly four feet long, about the size of an adult golden retriever. Early signs indicate the calf is healthy, and it has already started slipstreaming — drafting behind its mother to conserve energy while swimming.
Veterinarians will monitor key developmental milestones including:
-
Nursing behavior
-
Swimming strength
-
Bonding patterns
-
Social interactions
The first 30 days are critical, zoo officials said.
Exhibit Closed for Bonding Period
Brookfield Zoo’s Seven Seas exhibit will remain temporarily closed to the public as the calf bonds with its mother and adjusts to the dolphin group.
Officials also confirmed the calf will eventually undergo a paternity test to determine which male dolphin at the zoo is the father. A name for the calf will be announced later this summer.
