Polly want a conversation
BoingBoing has a post on the N’Kisi Project. In 2004, BBC News reported on a captive African grey parrot called N’Kisi. At the time N’Kisi had a vocabulary of 950 words, and showed signs of a sense of humour.
The N’Kisi Project is a series of controlled experiments and ongoing research in interspecies communication and telepathy conducted by Aimee Morgana and her language-using parrot N’Kisi. The images shown above are stills from the video document “Initial Interspecies Telepathy Experiments”, a research project with the collaboration and support of Dr. Rupert Sheldrake.
