3. Alex, the Gray Parrot
Bought as a one year old parrot, Alex became one of the strange animals under major scientific study when he was rumored to be able to utter some human sounds. According to his owner, Irene Pepperberg, Alex possessed the ability to utter some sounds like a human kid aged 4 years old.
His name Alex is an acronym of his owner’s “animal learning experiment’’. At the time of his death, Alex was able to recognize more than 50 subjects, and had a whooping vocabulary of over 100 words. The last words he uttered before he died are “you be good’’.
