Many people are aware of the 30-year long relationship Irene Pepperberg had with her African Grey Parrot, Alex (roughly May 1976 – 6 September 2007).
Irene Pepperberg was trained at Harvard in chemistry, but while writing her chemistry dissertation she became fascinated with the biological aspects of language acquisition in animals. She finished her chemistry dissertation but never used the degree directly. That said, however, she had learned many research and other transferable skills to enter into the biological field of animal psychology. She studied constantly -- about child acquisition of language, about animal cognition which at the time was believed to be almost non-existent. For years she battled disinterest in her studies, and especially flack from the scientific world in general; animals were strictly believed to be governed by instinct and intelligence wasn't to be considered. Until this time, language acquisition had only been testing in some primates, gorillas, and corvids (crows, ravens). Irene thought that a grey parrot, an animal known to talk, would be the ideal subject to research animal cognition and intelligence with, and so went to an exotic pet store to get one. One was arbitrarily scooped up, and that parrot became the famous talking Alex!

A video on YouTube "Alex: One of the smartest birds ever" shows some of his training to demonstrate that animals, precisely African Grey Parrots, can not only "parrot" humans but actually understand and communicate with them intellectually, rationally, intentionally - all aspects of intelligence previously denied possible in the animal world. Humans just couldn't wrap their brains around the fact that humans aren't positioned as the only "animals" that acquire and communicate with meaningful language.
Some anecdotes I pulled from the "Alex and Me" book, which become clearer after seeing this YouTube clip.
In his early years of training:
In training, Alex "was less interested in colors than the objects, probably because all the colors tasted the same, while the different objects had different tastes and textures."
"He loved chewing clothespins. We called them 'peg wood', which he picked up quickly. I then gave him a green clothespin, something he'd never seen before, and asked, 'What's this?' He looked at it and cocked his head a couple of times, obviously intrigued, as he often was with novel objects. He then looked at me and said, 'Green wood peg wood,' all one phrase. We hadn't modeled it, so this was striking. Of course, a perfect response would have been 'Green peg wood'.
[Pepperberg's early initial struggles with funding and getting published in a time when there was a growing controversy in the field of ape-human communication .... and therefore if apes weren't given legitimacy in communication, certainly no 'bird-brain' was going to get it! She writes:
The chimpanzee known as Washoe, for instance, in the care of Roger Fouts, had apparently coined the phrase "water bird" the first time she saw a swan; Koko the gorilla, the subject of Penny Patterson's research, seemingly described a zebra as a "white tiger". These efforts were garnering a lot of public attention (NOVA programs were just part of that; magazine and newspaper articles proliferated too). Yet linguists were expressing a growing unease over the claim that these animals had demonstrated a rudimentary facility for language.
In November 1979, Science published a long paper by Herbert Terrace and several colleagues: "Can an Ape Create a Sentence?" It was to become a classic in the growing controversy.]
Some language acquisition with Alex was unplanned, for instance, in December 1980 Alex was taken to a washroom on researcher Kathy Davidson's shoulder and he noticed his reflection in the mirror for the first time. He looked into it, cocked his head, and asked, "What's this?" Kathy answered, "That's you. You're a parrot." Alex looked some more and then asked, "What color?" Kathy said, "Gray. You're a gray parrot, Alex." And that was how Alex learned the word grey.
After several years of work with Alex:
Alex as as grey was very affectionate and loved to have his head lightly scratched. Lab workers called it tickling, so Alex when he wanted attention sometimes would lower his head and say, "You tickle", meaning "scratch my head". One day a stuffed gray was on the desk where Alex worked. After a bit he went over to it, gave it a good look, and then lowered his head to the stuffed bird and said, "You tickle." When nothing happened, he did it again. Again nothing happened, so in a huff, Alex said, "You turkey," and walked off. "You turkey" was a phrase the lab students sometimes said to Alex when he was uncooperative.
Another phrase he picked up inadvertently was "Pay attention!" He had aspergillus infection, a killer, and had to be taken to the vet and put into a nebulizer to help him breathe in drugs for treatment. Of course he didn't like it in the confining nebulizer. He knew he had to "wait" until the bell went off after the treatment, but one time there was an emergency and when no one came after his timer went off, he rapped on the glass and said not only his unhappy-with-this-environment phrase of "Wanna go back", he called out, "Pay attention! Wanna go back!" He had picked up "Pay attention" from students who were testing him in the lab.
At the vets, Alex was popular during the day, but at night he was basically alone. One night the accountant stayed late, and Alex tried to communicate with her. She was working so therefore quiet, so Alex asked, "You want a nut?" "No, Alex." He persisted, "You want corn?" "No, thank you, Alex, I don't want corn." This went on for quite a while with the accountant trying to ignore him in order to do work. Finally, Alex apparently in exasperation said in a petulant voice, "Well, what do you want?" The accountant cracked up laughing and gave Alex the attention he was demanding.
After recovery, Alex was taken back to the lab, but he didn't seem interested. In response to the question "How many wool?" based on the number of wool pieces on a tray, Alex answered, "One." The correct answer was two. When asked again, he said, "Four." Back and forth, one and four. Finally Irene said he would have to go into time-out and put him in his private room away from people. He immediately called out from behind the closed door, "Two ... come here ... two." Yep, Alex had fully recovered and was up to his old tricks!
Of course Alex wasn't the only bird in the lab. There were others like Griffin and Wart. Both were younger than Alex and both were obtained years after Irene had bonded with Alex, so Alex was king in the lab. He always had to have the higher perch, be closer to Irene's face in pictures and in communal work, and was therefore bossier. When Griffin was asked a question and didn't answer immediately, Alex would call out the answer (and sometimes the incorrect one to confuse Griffin). If Griffin's pronunciation wasn't clear enough, Alex would call out, "Say better" and Griffin better sound better on the next try.
Did Alex understand language? Well, what do you think?
Irene came storming into the lab one day angry to lose funding for her research ... yet again. Alex looked at her, and said, "Calm down!"
He babbled and played with sound when alone, for instance, "green, cheen, bean, keen ..." So one day while Irene was testing him with a photographer on a limited schedule, she was asking Alex questions related to phoneme sounds, something she'd never worked with Alex on, but because the interviewer was on a tight schedule Irene skipped giving Alex a reward for every correct answer because Alex eating a nut after each answer would take too much time. Alex was getting frustrated and at not being appropriately rewarded for his efforts and would call out, "Want nut!" He continued to answer each phoneme question correctly, despite never being asked such questions before, and after each would demand more loudly, "Want nut!" Finally, in exasperation Alex called out, "Want nut! Nnn ... uh ... tuh!" Irene was stunned! His response was equivalent to, "Hey stupid, do I have to spell it out for you?"
Could Alex put thoughts together to create new meaning? Well, one day someone brought a birthday cake into the lab and everyone shared it, including the birds. Community was very important for fostering communication and relationships. When Alex got his piece, he appreciatively said, "Yummy bread." He had known "yummy" and "bread" before, but putting them together was totally Alex's idea.
The night before Alex died, September 2007.
Alex stayed in the lab with the other birds, and every night before Irene would leave, she and Alex would say their parting words. Wart and Griffin said nothing.
Alex: "You be good. I love you."
Irene: "I love you too."
Alex: "You'll be in tomorrow?"
Irene: "Yes. I'll be in tomorrow."
And those were the last words Alex spoke to her, "You be good. I love you!" Irene treasures them!
