Alex the African grey parrot used words for concepts
AI-generated cover illustration: an African grey parrot studies several colorful geometric objects in a fictional research room. It is not Alex and does not depict the actual study. Origin: OpenAI image generation. Generated: 2026-10-20. Prompt: “Photorealistic vertical 4:5 editorial cover showing a mature African grey parrot perched in a calm research room, with a small set of colorful geometric wooden objects on a table nearby. The parrot watches the objects attentively; natural grey feathers, red tail, black beak, warm soft studio light. This is a fictional illustrative reconstruction of cognitive testing, not the famous parrot Alex and not a documentary scene. No people, no text, no labels, no cages.”
A well-studied example is Alex, an African grey parrot. In controlled experiments, he answered questions about objects with learned vocal labels, including identifying whether pairs of objects were the same or different in color, shape, or material. This indicates that at least one trained parrot used particular words to label concepts rather than merely repeat sounds; it does not mean that all parrots can do this or understand human language just as people do.
