When animal psychologist Irene Pepperberg entered a Northwest Side pet shop in 1977 and purchased an obnoxious one-year-old african blue parrot for sale grey parrot named Alex, she began a 30-year experiment that changed the way we view the intelligence of birds. Her research with him challenged the notion that birds only mimic human speech, without any understanding of meaning.
What is Alex?
Alex (short form for Avian Learning experiment) was initially an african grey parrots on sale grey parrot purchased at a pet store. However, over the course of his life, he led trails in animal psychology that were beyond anything previously thought possible, and he proved that animals can be as intelligent as dolphins or primates. Up until his death in 2007, Alex was one of the most famous talking birds in the world, appearing on TV programs and scientific reports.
In his life, Alex learned over 150 words and could identify colors, shapes, materials, and quantities of objects.
