Alex (1976–2007) was an African grey parrot studied by comparative psychologist Dr Irene Pepperberg for over thirty years, first at Purdue University and later at Harvard and Brandeis. Alex learned to identify around fifty objects, seven colours, and several shapes, and could count small sets of items, correctly answering questions like “how many blue blocks?” He used over one hundred words functionally — not simply through mimicry, but to request objects and answer novel questions, which was central to Pepperberg’s research into avian cognition. On the evening of 6 September 2007, Alex reportedly said to Pepperberg, as he did most nights, “You be good. I love you. I’ll see you tomorrow.” He was found dead the next morning. The exact extent to which Alex’s language use reflected genuine understanding, as opposed to sophisticated learned association, remains debated among researchers — the B2-C1 version of this lesson addresses that debate directly.

ReadingAlex Says Goodbye
Ellie and Max read a true story about a parrot.
Long ago, people thought parrots could only copy sounds, like a machine. They did not think parrots could understand words.
Then, a scientist named Irene got a grey parrot. She called him Alex. For thirty years, Irene taught Alex many things.
Alex learned the names of colours. He learned the names of shapes. He could count small groups of things, up to six! When Irene showed him two red toys and three blue toys, Alex could say how many toys there were.
Alex used more than one hundred words. He did not just copy sounds. He used words to ask for things, and to answer questions.
One evening, Irene said goodnight to Alex, like every day. Alex said, “You be good. I love you. I will see you tomorrow.”
The next morning, Alex was not there anymore. He died in the night.
Irene never forgot Alex’s last words. Now, scientists still study Alex’s story. They want to know how much parrots can really understand.
