Chimpanzee Behavior

New benches! + What’s with all the reassurance?

January 29, 2011 by Diana

J.B. has already applied his new welding skills by fabricating two new awesome benches for the playroom. Thanks to Barb from Ohio for aiding in the project by “adopting” J.B. and purchasing the workshop heater from our amazon.com wish list.

The video below mentions reassurance, which is really common among chimpanzees. This simplifies what can be complex behavior, but, in general, asking for reassurance can be a submissive or peacekeeping behavior, or it can be a way to ask, “are you on my side?” Giving reassurance can be saying, “everything’s okay between us” or “yep, I’ve got your back.”

In the first instance in the video, Jamie is submitting to Burrito and Burrito accepts her submission by doing a quick arm over gesture as he runs by. Looking at this 2 sec interaction in isolation, you might suspect that Burrito was dominant to Jamie, but looking at their interactions overall, that’s not the case. It could be that Jamie just wanted to acknowledge Burrito’s display but let Burrito know she wasn’t interested in starting any trouble with him, so she could get to work looking for food.

In the second instance in the video, Foxie is being submissive to Negra, probably not because Foxie thinks that Negra is going to start something, but because Foxie is respectful of those who are higher ranking and often plays the role of peacekeeper, keeping the group calmer by giving reassurance to whoever seems excited.

Chimpanzees are a bit tightly wound in general, and a high arousal situation such as a great food forage can quickly turn into a fight. So, in any high arousal situation, chimpanzees will be doing a lot of asking for and giving reassurance, even if the situation is a happy occasion. Sometimes the exchange of reassurance is more just a sharing in the excitement of the moment than a submissive or dominant behavior.

Imaginary play

January 11, 2011 by Jackie

This morning, while Elizabeth and I were cleaning the playroom, Annie was sitting in the window. She playfully opened her mouth for a “drink of water” through the glass. She’s not the only chimpanzee at CSNW that we have witnessed play this game. We caught a short clip of it:

This reminded me of something I saw, but failed to get on camera a few weeks ago. Jamie was sitting on this small toy horse and scooting along the playroom floor. She then lifted her leg up high and over in an exaggerated dismount. Two things stood out to me- the first was how interesting it is to me that chimps engage in this type of pretend play, and second- how truly little we know about the chimps’ histories. She seemed to know exactly what she was doing when she “dismounted”. We suspect she was a “pet” prior to the lab, but was she raised by a cowboy (hence the boot obsession?), did she just see this on TV?, or was she taught to ride a horse at some point? We may never know, but it was a fascinating moment none the less.

Here’s a photo of the horse, for scale. 🙂

Smiling?

October 29, 2009 by Jackie

For me, going to Blockbuster or Hollywood Video to look for a movie is always an interesting experience. It never fails- I will see a movie with a chimp on the cover “smiling”. This facial expression that we, as humans, understand as a happy face is not a happy face for a chimpanzee. A “human smile” displayed by a chimpanzee is actually a “fear grimace” and is displayed when a chimp is afraid or excited. When a chimpanzee is used for entertainment purposes, they are trained to fear grimace for the camera. I thought, in this regard, I would post some pictures to demonstrate the difference between a fear grimace and a chimpanzee smile.

Below is an older picture of Jody displaying a fear grimace. If I had to guess, I would say she was afraid someone might steal her watermelon…

Here is a picture of Jody with a playface or a chimpanzee smile. THIS is a happy chimpanzee:

and a happy Foxie:
