The African grey parrot is considered the most intelligent bird species, capable of learning over 1,000 words and understanding concepts like shape, color, and number. Alex, the most famous African grey, could identify 50 objects, 7 colors, and 5 shapes, and understood 'zero' as a concept. They live 40-60 years in captivity and form deep bonds with their owners.
