Orangutan Personalities

Ever wonder about the personalities of the orangutans and siamangs you watch on Ape Cam? Wonder no more! Here’s a quick guide to help you tell “who’s who.”

Janey is the oldest animal in the exhibit. At approximately 52 years old, her hair is thinning on her back and shoulders, and her toes are curled up (it is painful for her to straighten them out). You may see her crutch-walking on exhibit. She is on medications, due to her age, for pain and gut mobility. She is our only Borean orangutan, born in the wild around 1962. She remains interested in “human items” due to the fact that she was hand raised and in private hands for the first half of her life. Her favorite spots in the exhibit are at the exhibit glass and in her zen/sun spot down the hill. She gets along with everyone in the group. But do not let her old age fool you! She lets her feelings be known, and she stands her ground.

Karen was born at the Zoo on June 11, 1992, and was hand raised. She survived a widely publicized open-heart surgery in 1994. Karen is very short and round (a no-neck girl!). Her hair is shorter than Janey and Indah’s, and her eyes are yellow. She has a LOT of personality, is very stubborn and willful but remains a keeper and guest favorite. Karen likes to twirl around on the sturdy bamboo poles in the exhibit. She also likes to roll around instead of walking when out there (she will and can walk, but chooses not to!).

Indah likes to sit in the far right (east) climbing structure. She rarely comes down to the ground, and then only to get food and be at the popular man-made termite mound to grab a snack. Indah is the pretty one of the group with long, flowing hair and a large bump in the middle of her forehead. She is very slow to warm up to new people, but she likes the siamangs and shares her food with them occasionally (an unusual behavior in the primate world!). She was a very doting mother to little Aisha, born in 2013.

Satu is our lone male orangutan and is Aisha’s father. He was born on March 26, 1995. His cheek pads and dreadlocks filled out once his father, Clyde, moved to another zoo. Satu has a sweet disposition and can usually be seen slightly down the hill in a bed of pappas grass. He is quite playful and often plays with the two siamangs that share the exhibit.

Aisha is our newest orangutan, born on October 25, 2013, to mother Indah. So far, her mother is doing a great job of caring for her, and little Aisha is skilled at clinging to Mom’s chest as the pair travel up poles and across the ropes. What fun we’ll have watching her grow!

Of our two siamangs, Unkie is much leaner than Eloise and his face is more angular. Siamangs pair bond for the life of their mate, and Unkie and Ellie have been together since 1987 and can often be heard singing duets.

Unkie, born on October 19, 1983, is usually the instigator with the orangutans; he likes to steal their food, pull on their hair, and swat at them. Eloise, born on April 17, 1981, has a visible belly and a bare chest. There is a discolored line of hair down the middle of her back. She has had five offspring with Unkie. The siamangs both are very sweet, not too aggressive to people or their orangutan roommates.

Now that you know a bit more about them, I hope you’ll continue to enjoy watching all the action on Ape Cam!
