WALTHAM, MA (SEPTEMBER 10, 2007)—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.
In 1973, Dr. Pepperberg was working on her doctoral thesis in theoretical chemistry at Harvard University when she watched Nova programs on signing chimps, dolphin communication and, most notably, on why birds sing. She realized that the fields of avian cognition and communication were not only of personal interest to her but relatively uncharted territory. When she finished her thesis, she left the field of chemistry to pursue a new direction—to explore the depths of the avian mind. She decided to conduct her research with an African Grey parrot. In order to assure she was working with a bird representative of its species, she asked the shop owner to randomly choose any African Grey from his collection. It was Alex. And so the 1-year old Alex, his name an acronym for the research project, Avian Learning EXperiment, became an integral part of Pepperberg’s life and the pioneering studies she was about to embark upon.
Over the course of 30
years of research, Dr. Pepperberg and Alex revolutionized the notions
of how birds think and communicate. What Alex taught Dr. Pepperberg
about cognition and communication has been applied to therapies to help
children with learning disabilities. Alex’s learning process is based
on the rival-model technique in which two humans demonstrate to the
bird what is to be learned. Alex and Dr. Pepperberg have been
affiliated with Purdue University, Northwestern University, the
University of Arizona, the MIT Media Lab, the Radcliffe Institute, and
most recently, Harvard University and Brandeis University.
Alex has
been featured worldwide on numerous science programs including the BBC,
NHK, Discovery and PBS. He is well known for his interactions with Alan
Alda in an episode of Scientific American Frontiers on PBS and from an
episode of the famed PBS Nature series called “Look Who’s Talking.”
Reports on Alex’s accomplishments have appeared in the popular press
and international news from USA Today to the Wall Street Journal and
the New York Times. The Science Times section of the New York Times
featured Alex in a front-page story in 1999. That same year, Dr.
Pepperberg published The Alex Studies, a comprehensive review of her
decades of learning about learning from Alex. Many other television
appearances and newspaper articles followed.
Alex was found to be in good health at his most recent annual physical about two weeks ago. According to the vet who conducted the necropsy, there was no obvious cause of death. Dr. Pepperberg will continue her innovative research program at Harvard and Brandeis University with Griffin and Arthur, two other young African Grey parrots who have been a part of the ongoing research program.
Alex has left a significant legacy—not only have he and Dr. Pepperberg and their landmark experiments in modern comparative psychology changed our views of the capabilities of avian minds, but they have forever changed our perception of the term “bird brains.”

The Pathology results:
Alex died quickly. He had a sudden, unexpected catastrophic event
associated with arterosclerosis ("hardening of the arteries"). It was
either a fatal arrhythmia, heart attack or stroke, which caused him to
die suddenly with no suffering. There was no way to predict his demise.
All of his tests, including his cholesterol level and asper levels,
came back normal earlier that week. His death could not be connected to
his current diet or his age; our veterinarian said that she has seen
similar events in young (<10 year old) birds on healthy diets. Most
likely, genetics or the same kind of low-level (impossible to detect in
birds as yet) inflammatory disease that is related to heart disease in
humans was responsible.
