(Portland, OR) -- The Oregon Zoo's youngest member of the orangutan family celebrated her first birthday this week. Jolene was born April 13, 2022. She's learning to walk and climb on her own, but she doesn't venture far from her mom, Kitra. Orangutans stay with their mothers for 8 to 10 years. The bond between an orangutan mom and her baby is one of the closest of any species.
