How intelligent are African greys?


Anecdotal evidence from those who care for African grays has long suggested that the parrots possess high innate intelligence. American animal behaviourist and psychologist Irene Pepperberg vindicated those observations with her studies of the cognitive abilities of African grays, using a bird named Alex and, later, additional specimens.How intelligent are African greys?

Among his most significant accomplishments was proving unequivocally that parrots could associate sound and meaning, demolishing long-held theories that birds were capable of only mimicking human voices. At the time of his death in 2007, he could use English to count to six, correctly label objects of five shapes and seven colours, and differentiate groups of objects by colour, material, and shape. He further used English to communicate to other African grays in Pepperberg’s lab, variously encouraging and chastising their efforts at labeling and categorization.How intelligent are African greys?

Conservation status

A 2003 United Nations Environment Programme (UNEP) study estimated that nearly 660,000 African grays were sold on the international market between 1982 and 2001. Extrapolations suggested that more than 300,000 additional birds likely died during capture or transport. The European Union banned the importation of wild-caught birds in 2007. Nonetheless, significant markets existed for the trade of African grays in the Middle East, in East Asia, and within Africa itself.

Estimates of the total wild population in the early 21st century ranged as high as 13 million, though precise surveys were impossible because the parrots live in isolated, often politically volatile regions.
