Lincoln Park Zoo announced on April 10 that Kapuki, a 20-year-old eastern black rhinoceros, gave birth to a female calf weighing about 60 pounds on March 19. The arrival of the new calf marks an important event for the zoo and raises several questions among visitors about rhino pregnancies and care.
The birth is significant as it contributes to efforts to preserve genetic diversity among critically endangered species living outside their natural habitats. Christine Bobko, president of the International Rhino Keeper Association, said that breeding recommendations help create a “genetic backstop” if animals like the eastern black rhinoceros go extinct in the wild. The pairing between Kapuki and Utenzi, the father of her third calf, was arranged through a species survival plan managed by the Association of Zoos and Aquariums.
Kapuki’s match was selected based on lineage, breeding history, personality traits, age, and space availability at zoos across North America. Cassy Kutilek, Lincoln Park Zoo’s curator of large mammals and carnivores, traveled to Cincinnati to observe Utenzi before recommending his move to Chicago. Bobko described rhino courtship as challenging: “Rhino love is not champagne and roses,” she said. “It’s a battle zone.” The introduction process included gradual exposure before allowing direct contact between Kapuki and Utenzi.
Pregnancy announcements for rhinos do not follow human customs due to risks such as stillbirths or miscarriages during their lengthy gestation period of around sixteen months. Kutilek noted that changes in behavior were used alongside hormonal analysis to confirm pregnancy since false positives are possible.
The newborn will remain out of public view for several weeks while bonding with her mother under remote monitoring by zoo staff. Naming will be handled by a committee focused on cultural sensitivity; Anna Cieslik from Lincoln Park Zoo said names may reflect people connected with conservation efforts or indigenous languages from native habitats.
Bobko remarked on how much joy baby rhinos bring: “When you have a baby rhino, you don’t get a lot of work done,” she said. “You spend a lot of time just enjoying the antics. There’s nothing more joyful, quite honestly.”
