The Buffon's subspecies of the Guinea Turaco is the only Green Turaco with no white line below the eye.
The nominal Guinea Turaco, also confusingly called the Green Turaco, has a white line above and below the eye, as do several other Turacos.
It has a blue-black back end and red wing edges but no white on top of its crest. It is native to west-central Africa.
It has a red bill, although, unusually, the Buffon's Turaco on the above right photo has
a black and mis-shapen bill.
The red wing and the blue-black back and rump. "Buffon" does not refer to the bird's bouffant hairdo but to
the French naturalist Comte de Buffon.
