how many words can a grey parrot learn
Grey parrot Grey parrots are also highly intelligent, having been shown to perform at the cognitive level of a 4â€“ to 6-year-old child in some tasks. New experiments have shown that grey parrots can learn number sequences and can associate human voices with those humans' faces.[17] Most notably, Dr Irene Pepperberg's work with Alex the parrot showed his ability to learn over 100 words, differentiating between objects, colours, materials, and shapes.[18]
