It is one of the most intelligent species in the world. The Gabon gray parrot is said to have the intelligence of a 5-year-old child. In addition to being clever, the bird would also be endowed with a great sense of mutual aid. Scientists from the University of Munich in Germany recently conducted a test on several animals to test their intelligence and helpfulness. Of more than 100 species, only humans, bonobos, orangutans and African gray parrots have passed this test of helping another animal find food.
