YouTube is an amazing site. It’s incredible how many videos people have uploaded to it. I use it a lot to find videos with medieval and renaissance music, which is a music genre I am especially fond of. I also love to find videos about things from my childhood and past to sit back in nostalgia. There are also quite some videos on YouTube about ape language research. I would like to draw your attention to the following interesting films and documentaries about ape language that have been put on YouTube. In 1976 the Franco-Swiss movie director Barbet Schroeder (known from films such as Barfly) made the movie Koko, le gorille qui parle (Koko, the talking gorilla). The film shows the how signing gorilla Koko lives and signs with Penny (Francine) Patterson, who taught signs to Koko and continues to study her signing up to this day. It also includes several parts with Roger Fouts and the signing chimpanzees Washoe and Ally at the Institute for Primate Studies at the University of Oklahoma, where they lived in the 1970s. You can watch the whole movie in 8 videos on the YouTube channel of tehinfidel. Click here to go to the first video of the movie and find the other seven parts of the movie. Another great ape language documentary is ChimpTalk, made by the BBC’s Horizon programme in 1993. It shows the history of the language projects with chimpanzees and has great parts showing the signing chimpanzees Washoe and Nim Chimpsky, as well as the lexigram using bonobo Kanzi. It also includes interesting interviews with the Fouts, Herbert Terrace and Sue Savage-Rumbaugh. Click here to go to the channel of Barbaste, who put the documentary there in 6 parts. Another very interesting YouTube channel with lots of ape language videos is that of J. Patrick Malone, a Ph.D. student in evolutionary psychology in Missouri. His channel is called PhD4NonhumanPrimates and includes several videos from the Gardners 1973 film Teaching sign language to the chimpanzee Washoe. Check out his channel by clicking here. The Great Ape Trust in Des Moines, Iowa, where the bonobos Kanzi and Panbanisha continue using lexigrams to communicate with humans has its own YouTube channel with multiple videos showing the apes using lexigrams.

I haven’t uploaded videos there yet, but I have favorited many videos about animal communication and language research with animals and made a special playlist about this theme. Check out all of these interesting videos!
