Aisha is becoming more independent, agile, and bold!
Two years have flown by and our little girl had another birthday (October 25)! Recently, we have a seen a lot of milestones in Aisha’s behavior. She is becoming more independent and Indah is more comfortable letting her explore on her own. In just the last two months, we have seen Aisha follow her mom to the front glass, increase her amount of play with her “aunties,” and even come down to the ground on her own.
Indah has started to leave Aisha and is letting her decide if she wants to follow. Most of the time, Aisha decides to join her. But the first few times Aisha walked on the ground, she was very hesitant; she particularly did not like the sand at the front of the exhibit and called for her mom to get her, so she did not have to touch it. She now crawls across it with little hesitation.
We have even seen her come to the ground without anyone being near. At first she came to the ground because Indah or another orangutan was there. But recently she came and pulled grass to eat and play with when no one else was around. All of this behavior is mimicking what she has seen from her mom.
In just the past week, we have seen an increase in the length of play between Aisha and Janey and Karen (the latter in particular). Karen clambers up into the climbing structure near Aisha and waits for the youngster to initiate play. (Aisha will leave if Karen is too pushy and tries to touch her first.) They play and wrestle on the ropes and in the hammocks. Sometimes it looks quite rough, but it is all play behavior. When Janey wants to play with Aisha, she goes to a spot on the ground that she knows the little one can reach from a rope or tree and waits for her to come to her. Once Aisha is more comfortable on the ground, I suspect we will see a lot more play between her and Janey.
The bond between Aisha and Indah continues to be incredibly strong. Aisha still goes to mom whenever she is anxious, and we have not ever separated Aisha from Indah. We are starting to work with them to be comfortable separating from one another. We want to be able to get frequent weights on Aisha—this is important for the species database on what is the normal range for a parent-raised infant. We also want to start her operant training so we can monitor her health as she grows and becomes an adult.
