Gray Parrot

Widely regarded as the most intelligent parrot species and the most capable avian mimic, African grey parrots can develop vocabularies of over 1,000 words and demonstrate comprehension of concepts including zero, color, shape, and relative size. Native to equatorial African rainforest from Ivory Coast to Kenya, they live in large flocks. Endangered due to catastrophic trapping for the pet trade — up to 21% of wild birds are trapped annually — and deforestation. Strict CITES Appendix I trade restrictions apply.
