What caused the death of Alex the Parrot?

Answer 1

Alex (1976 - September 6, 2007) was an African Grey Parrot and the subject of a thirty-year (1977-2007) experiment by animal psychologist Irene Pepperberg, initially at the University of Arizona and later at Harvard and Brandeis University. Pepperberg bought Alex in a regular pet shop when he was about one year old. The name Alex is actually an acronym for Avian Learning EXperimentOn October 4, 2007 The Alex Foundation posted the following 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.
