Psittacus erithacus timneh
There are two strongly differentiated subspecies, Congo African Grey (P.e. erithacus) from Central Africa, and Timneh African Grey (P.e. timneh), darker and with upper mandible dark red tinged black, from West Africa.
This species is listed as Near Threatened because a recent analysis suggests that up to 21% of the global population may be harvested annually (during 1994-2003, over 359,000 wild-caught individuals were reportedly exported from range states). In combination with the rate of ongoing habitat loss, the species is therefore suspected to be declining moderately rapidly.
