Helmeted guineafowl are great runners, and can walk 10 km and more in a day. They make loud harsh calls when disturbed. Their diet consists of a variety of animal and plant food; seeds, fruits, greens, snails, spiders, worms and insects, frogs, lizards, small snakes and small mammals. Guineafowl are equipped with strong claws and scratch in loose soil for food much like domestic chickens, although they seldom uproot growing plants in so doing.
