When given paintbrushes and paint, the KUPRI chimpanzees paint pictures, even though we don't give them any food rewards for doing so. It seems that, just like humans, they enjoy painting for the sheer pleasure of it.
The following are our favourite masterpieces that we'd love to share with you. Please enjoy the drawings by Ai and other chimpanzees at KUPRI, and then those by Kanzi, Washoe and Koko.
Video: Here is a female chimpanzee named "Ai", then aged 36 (est.), painting a picture. She is quite the artist; such wonderfully bold brushstrokes ♥
Based on this red-and-black painting by the chimpanzee Ai,
we created a scarf in 2017 for the 40th anniversary of the Ai project, as the special anniversary commemorative gift.
