Einstein and Zac the parrots
All right, since there seems to be so much interest here, you might want to check out: birds.about.com/b/a/158854.htm and click on the video of Einstein the African Grey. There is another video about Zac, a macaw, but Einstein steals the show!
A book about parrots that is also tied in with the kind of work I do on intelligence and brain function in humans is "The Parrot Who Owned Me" by Dr. Joanna Burger.
I'll stop talking about parrots and get back to work now. Cheerio.
