"One June day in 1977, Irene Pepperberg walked into a pet store looking for an African grey parrot." Of the several available, she singled out one bird to be part of an experiment--the Avian Learning Experiment--at Purdue University. Through her work with Alex, scientists learned that, far from being barely intelligent creatures, some animals, including parrots, are highly intelligent and capable of understanding the words they hear--and in the case of parrots and mynah birds--those they say.
Interestingly the genesis of Irene Pepperberg's interest in animal intelligence started in 1974 when she saw a
Alex was in many ways an ordinary parrot. He imitated noises he heard but spoke as clearly as a person, something not possible for a chimp or a dog or a dolphin. Budding scientists will appreciate following the processes and methods Irene used to teach Alex and her attempts to discover whether he really understood what he was saying. Like a petulant toddler "no" became one of his favorite words. Importantly, the book also explains why the research had to be meticulously document so that it would not be dismissed as operant conditioning like "Clever Hans," a horse who performed math problems by picking up cues from his handler. Eventually Alex could understand and say hundreds of words, many more than Washoe, a chimp who could sign 130 words, or Koko, who could sign 200 words. Alex even understood concepts like bigger or smaller and the concept of zero--something children don't grasp until they are about four or five years old. Alex even became an avian celebrity, appearing on television shows.

The illustrations by Meilo So, who also illustrated Pale Male: Citizen Hawk of New York City, shows Alex in exquisite watercolor detail with sketchier 1970s style scenes around him. So used colored pencils and ink to provide additional illustrations. The hand-letter type uses the same shaped letters Alex used in his testing and cartoon-like bubbles show his dialogue.
Adults or teen readers who want to know more can read Alex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence--and Formed a Deep Bond in the Process, Pepperberg's book about her life with Alex. Readers from about third grade through middle school will learn a lot about African Grey Parrots and animal intelligence and this is a great companion book for a longer fiction book like The One and Only Ivan by Katherine Applegate, about a gorilla that communicated with people.
I received a review copy of this book from the publisher, Alfred A. Knopf.
