למרות שהויכוח בין העסקים בדבר עדיין לא נסגר יש הטוענים שיש 3 סוגי ג'אקו.
There are only three distinct birds in this genus. Whether or not they are different species, subspecies or simply variants of the main species, Psittacus erithacus, is still open for debate.
The African Grey Congo, Psittacus erithacus, is found in the west-central part of Africa mainly within 10 degrees north and south of the equator.
The African Grey Timneh, Psittacus erithacus timneh, differs from the Congo in its size, being noticeably smaller, in its maroon tail, and the pink color of the upper third of the upper mandible . The Timneh naturally occurs in Liberia, Sierra Leone, and the westernmost parts of the Ivory Coast.
Another seldom seen African Grey, Psittacus erithacus princeps, can only be found on the islands of Principe and Gernando Po in the Gulf of Guinea. This bird is darker than the regular African grey
