Alex was an extraordinary African Grey parrot who became famous for his remarkable intelligence and ability to communicate. Trained by animal psychologist Dr. Irene Pepperberg, Alex could understand and use over 100 words, and he was even able to recognize shapes, colors, and quantities. Unlike most animals that are trained to repeat words without understanding, Alex demonstrated a level of comprehension that suggested he could grasp some of the concepts behind the words. He could ask for what he wanted, express preferences, and even make jokes. Alex’s abilities challenged the belief that only humans have the capacity for complex communication and cognitive skills, making him one of the most well-known and studied parrots in the world. His legacy continues to influence the fields of animal cognition and psychology.
