Numida meleagris (Linnaeus, 1758) |
The helmeted guineafowl (Numida meleagris) is the best known of the guineafowl bird family, Numididae, and the only member of the genus Numida. It is native to Africa, mainly south of the Sahara, and has been widely introduced into the West Indies, Brazil, Australia and Europe (e.g. southern France).
In the early days of the European colonisation of North America, the native wild turkey (Meleagris gallopavo) was confused with this species. This led to the English name of the American bird, since Turkey and Guinea were equally far-off and exotic places. The word meleagris, Greek for guineafowl, is also shared in the scientific names of the two species, although for the guineafowl it is the species name, whereas for the turkey, it is the name of the genus and (in an altered state) the family.
There are nine recognized subspecies:
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. Various sub-species are proposed, differences in appearance being mostly a large variation in shape, size and colour of the casque and facial wattles.
This is a gregarious species, forming flocks outside the breeding season typically of about 25 birds that also roost communally. Guineafowl are particularly well-suited to consuming massive quantities of ticks, which might otherwise spread lyme disease. These birds are terrestrial, and prone to run rather than fly when alarmed. Like most gallinaceous birds, they have a short-lived explosive flight and rely on gliding to cover extended distances. 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. As with all of the numididae, they have no spurs.
