African Grey Diet:

African Grey feed on seeds, nuts, fruits and berries gathered mostly in the treetops. When feeding they usually climb from branch to branch, rather than flying, and will hold the fruit or nut in its foot to eat. Grey Parrots are especially fond of eating the outer oily flesh of the oil-palm nut.

African Grey also prefer the red fruits of the Cola tragacantha, when available being careful not to eat the stone. They have also acquired a fondness for grain, and in West Africa they do immense damage to maize crops. It is almost impossible to drive them away because they become so bold.
