  • Largest of the guineafowl species.  Measures 61-71 centimeters long, with a round body and small head.  Weigh 1-1.6 kilograms.  Males are slightly larger than the females.  Wings, neck, legs, and tail are longer than those of other guineafowl species
  • Sexes look alike.  Body plumage is black with fine white speckles, except for the breast, which is bright blue.  The face and neck are bare; the face is blue, darkening to black, with a small ruff of brownish feathers at the back of the neck.  There is a cape of long, glossy blue and white feathers around the neck.  Juveniles similar to adults, but duller
  • Very terrestrial, if confronted with danger with run rather than fly (speeds up to 35 kilometers per hour).  Roosts in trees at night for safety
  • Males can be very aggressive not only to one another (sometimes fatally so) but to females; even though the sexes look alike, they can often be distinguished by behavior and posture
  • Genus name translates to "small peak," (absent the crest seen in many guineafowl), species name means "vulture-like" in reference to naked head and neck
  • Hunted locally for food, but population is considered secure in wild
