The Helmeted Guineafowl is a large (53–58 cm) bird with a round body and small head. They weigh about 1.3 kg. The body plumage is gray-black spangled with white. Like other guineafowl, this species has an unfeathered head, in this case decorated with a dull yellow or reddish bony knob, and red and blue patches of skin. The wings are short and rounded, and the tail is also short.
This bird was photographed in Sydney's Taronga Zoo. It breeds in Africa, mainly south of the Sahara, and has been widely introduced into the West Indies, Brazil and southern France.
