Happy 45th Birthday, Mari!
Today, we’re celebrating orangutan Mari, one of only two purebred Sumatran orangutans at the Center for Great Apes!
Mari is intelligent, observant, and independent, with a distinctive way of letting her caregivers know what she wants. She often purses her lips when making a request, and she’s willing to persist until her caregivers figure it out! Recently, after several suggestions were met with disinterest, a caregiver discovered that Mari’s favorite juice-jug straw had slipped underneath a TV cart. As soon as it was retrieved, Mari began squeaking with excitement. Mystery solved!
Mari was born without arms, but she has developed her own ways of navigating her environment using her feet, legs, and remarkable adaptability. She enjoys exploring the sanctuary’s aerial trailways and recently chose to stay in the trailway rather than move to either of the two outdoor habitats offered to her. Her care team also continues to make thoughtful modifications, including specially designed ladders and ramps, to help her access more spaces comfortably as she gets older.
And when it’s time to relax? Mari loves the sound of running water! She’ll sometimes plug her water lixits just to hear the water flow. She often requests that her caregiver run the hose into her habitat so she can gather a blanket, tuck herself underneath it, and stretch out on her back to enjoy the soothing sounds.
A special thank-you to Kim H., one of Mari’s adoptive parents and today’s Day Sponsor! Thank you for helping provide for Mari’s daily care and birthday treats. Your support helps make individualized care possible for Mari and all the apes at the sanctuary.
