Orangutan: 10 Teeth and Counting!

Aisha knows Mom Indah is never far.

Aisha knows Mom Indah is never far.

It seems that orangutan youngster Aisha is getting a new tooth every two weeks! At almost nine months old, she now has a mouth full of teeth and is putting them to use. All day long Aisha is finding food and trying it out. On exhibit she tries the leaves on branches, lettuce, and anything else she can get away from her mom. Indah has gotten better about sharing her food with Aisha; she is even letting Aisha have a couple of pieces of her fruit in the morning. When inside, Aisha tries all of Indah’s food, even the biscuits. Yet with all this food exploration, Aisha’s primary source of food is from nursing.

Aisha can often been seen climbing on the ropes and hammocks in the exhibit, spending an increased time off of Mom. There are times when Aisha wants to climb, but Indah won’t allow her. Yet there are occasions when Indah prefers Aisha to climb rather than hang on her, but Aisha won’t let go. Sounds familiar, right moms? Aisha still spends most of her time on exhibit hanging onto Indah, so you might need to spend some time at the exhibit to see Aisha climbing and hanging around.

Inside the orangutan bedrooms, if Aisha is awake, she is off and running. Well, not running exactly, but she doesn’t stay idle for long. She is climbing and moving all around her bedrooms. Indah is now comfortable enough that she does not immediately pick up Aisha when we come into the building. Aisha is curious about people and will come over to the bars and reach out to us if we have something that she wants or is curious about. While Aisha is off Mom a lot, she still will not leave her or go anywhere without her.

I often get asked when we will be putting the siamangs and Indah and Aisha together. At this time, we do not want to rush the process and have not yet set a date for introductions. If we put them together too soon, we run the risk of Unkie, the male siamang, being aggressive and potentially hurting Aisha or causing Indah undo stress. We want to avoid any negative interaction. It is best to wait until Aisha is more mobile and Indah is confident in Aisha’s safety. This is still months away from any consideration.

I truly appreciate everyone’s support for our orangutans, and with your support, we can help save this species for future generations.
