Raven Explores

Baby chimpanzee Raven still spends most of her time clinging tightly to her mom, Utamu. However, mom is starting to set Raven down next to her on their wood wool nest several times a day so Raven can stretch her legs, explore the world around her, and work on learning how to crawl and stand. Utamu continues to stay protectively next to her baby, and keepers often see the two engaging in play sessions. Sometimes Utamu even lets another chimpanzee, such as Grandma Rosebud, engage in play and grooming sessions with little Raven.  

Raven was born on October 28, 2020. To learn more about Raven and Utamu, visit
