Imaginary Play

Chimpanzees have rich imaginary lives. Chimps who use American Sign Language have been observed signing to inanimate objects and engaging them as if they were live social partners. For example, a chimpanzee named Dar was once seen signing “tickle” to a stuffed bear that he was playing with. I personally recall (and will never, ever…

Fall mornings

The chimps love these cool fall mornings. As soon as we’re done serving breakfast in the greenhouse, they pack up whatever they have left – in this case chow bags and pomegranate rinds – and head out to the hill take in the view.

Your Inner Chimp

You’ve got a chimpanzee lurking inside of you. This might come as a surprise, I know. But you might as well embrace it because whether you like it or not, your inner chimp will always find a way to reveal himself.

After decades of isolation and prolonged periods of fear and uncertainty, they have found someone to love, someone to trust, someone to comfort them in times of need.

They curled up next to one another in cozy nests,…

Learning to speak chimp

The thing that originally sparked my interest in chimpanzees was the fact that they could learn sign language. Ape language studies of the ’60s and ’70s not only helped bridge the gap between the complex languages of humans and the seemingly much simpler grunts, barks, and chirps of other animals, but they hinted at a…

Adapting

People who have been incarcerated for long periods can have trouble adapting to life outside prison once they are released, a phenomenon we call institutionalization. Chimps are no different. For the Cle Elum Seven, life in the lab was horrible, but after as much as 35 years it made some kind of sense. The deprivation…
