The pathology tests are finally back regarding the sudden death of Alex the Congo African Grey parrot.
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 appparently no suffering. There was no way to predict his demise. All of his tests, including his cholesterol level and aspergillosis levels, came back normal earlier that week. His death could not be connected to his current diet or his age; the veterinarian said that she has seen similar events in young (younger than 10 years 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.
