"Alex the Grey Parrot, Colleague of Irene Pepperberg, Dead at 31"


Alex, the world renowned African Grey parrot made famous by the ground-breaking cognition and communication research conducted by Irene Pepperberg, Ph.D., died at the age of 31 on September 6, 2007. Dr. Pepperberg’s pioneering research resulted in Alex learning elements of English speech to identify 50 different objects, 7 colors, 5 shapes, quantities up to and including 6 and a zero-like concept. He used phrases such as “I want X” and “Wanna go Y”, where X and Y were appropriate object and location labels. He acquired concepts of categories, bigger and smaller, same-different, and absence. Alex combined his labels to identify, request, refuse, and categorize more than 100 different items demonstrating a level and scope of cognitive abilities never expected in an avian species. Pepperberg says that Alex showed the emotional equivalent of a 2 year-old child and intellectual equivalent of a 5 year-old. Her research with Alex shattered the generally held notion that parrots are only capable of mindless vocal mimicry.
Read more on the passing of this splendid individual at GrrlScientist's excellent blog, and from Christine Kenneally at the Huffington Post. From the NY Times:
Even up through last week, Alex was working with Dr. Pepperberg on compound words and hard-to-pronounce words. As she put him into his cage for the night last Thursday, Dr. Pepperberg said, Alex looked at her and said: “You be good, see you tomorrow. I love you.”
Safe journey, Alex, and thanks.

I'll never forget that little parrot identifying things.

"Wood" was my favourite, I loved the way he said "wood". It was years ago that I saw him on TV and I find myself remembering it fairly often.

What a shame, rest in peace little guy. You were one cool little bird.
