African Grey Parrot: Species in Decline (English)
14 September 2016
The African Grey Parrot – a highly intelligent bird that is popular as a pet – has been eliminated from much of its west African range and the largest populations are now only found in central Africa. In the fall of 2016, delegates from around the globe will meet for the world’s leading forum to debate and discuss issues related to international wildlife trade – the 17th meeting of the Conference of the Parties (CoP17) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora, or CITES. Parties will consider a proposal to transfer the African Grey Parrot (Psittacus erithacus) from Appendix II to Appendix I, effectively banning international commercial trade in the species.

Increased Protection for a Bird Being Loved to Death
The Gray Parrot, also known as African Grey Parrot, is one of the world’s most popular pet birds—but that popularity has fueled the capture of millions of parrots from the wild in Africa. Earlier this month, an international wildlife trade conference granted this declining species increased protections under the Convention on International Trade in Endangered Species (CITES). The Cornell Lab’s Multimedia Productions program produced this video summary about the plight of the Gray Parrot for the government of Gabon and the United States Fish and Wildlife Service.
