Helmeted Guineafowl

The helmeted guineafowl is a large, round-bodied bird with grey-black plumage speckled in white and an unfeathered head topped by a bony knob. It is native to Africa, mainly south of the Sahara, where it breeds in warm, fairly dry, open habitats such as savanna and farmland. Gregarious outside the breeding season, it forms flocks of about 25 birds that roost together and prefers to run rather than fly when alarmed. Its diet shifts with the season: seeds, tubers and crop spillage in the nonbreeding months, and mostly invertebrates such as beetles during breeding. It is also widely kept as a domesticated bird.

About the helmeted guineafowl

The helmeted guineafowl is a large, round-bodied ground bird native to Africa south of the Sahara. It is the best-known member of the guineafowl family, Numididae, and the only species in its genus. A gamebird of the order Galliformes, built rather like a chicken or grouse, it has been domesticated and introduced to the Americas, Europe and Australia.

Linnaeus first named it in 1758 as Phasianus meleagris, then moved it to the new genus Numida, Latin for "North African," in 1764. Today it is Numida meleagris. The species name, meleagris, is Greek for guineafowl, and it echoes the scientific name of the wild turkey. Early European colonists in North America actually confused the two birds. Nine subspecies are recognized, differing mainly in the shape, size and color of the casque and facial wattles.

The bird is 53–58 cm (21–23 in) long and usually weighs about 1.3 kg (2.9 lb), with a heavy, rounded body, a small head and short, rounded wings and tail. Its plumage is grey-black to dark grey, evenly speckled with white dots, and a single feather can carry a dozen or more spots. The legs and feet are dark grey. Like all guineafowl, it has no leg spurs.

The head is the giveaway. It is bare of feathers, and the skin on the face and upper neck is sky blue to dark blue, with red patches. On top of the crown sits a bony knob called a casque, the "helmet" in the bird's name, which is dull yellow to reddish. Both sexes have a casque and wattles, but the male's casque is usually larger and the female's wattles are smaller. Juveniles are greyish brown with paler faces and smaller casques. The chicks, known as keets, are brown with black stripes on the head.

Behavior and diet

Helmeted guineafowl are social birds. Outside the breeding season they form flocks, typically of about 25 birds, though groups range from a single pair to around 100. Flocks spend the day on the ground and roost together in trees at night for safety. Within a big flock the birds chase and fight each other to settle rank, and flocks clash with neighboring flocks over territory. They clean their feathers with daily dust baths.

These are walkers and runners. A guineafowl can walk 10 km (6.2 mi) or more in a day, and its body is built for keeping steady while running fast over rough ground. When alarmed it would rather run than fly. Like most gamebirds, it can manage a short, explosive burst of flight, angling steeply upward, and then glide to cover longer distances. Guineafowl are diurnal and also crepuscular, active around dawn and dusk, scanning constantly for danger as they forage.

They are noisy. Calls are harsh, dry and carry a long way. Males give a single "chek," while females repeat a two-note "buck-wheat." The alarm is a loud, rattling "kek-kek-kek-kek-krrrrr" that warns other birds and animals nearby, and calls get louder and faster when the birds are excited.

Guineafowl eat both plants and animals. Out of the breeding season they eat mostly grain, tubers and seeds, especially of farm weeds, and pick up spilled crops. During the breeding season more than 80% of the diet may be invertebrates, particularly beetles. They also take snails, insect larvae, frogs, small lizards and mice, and they swallow small pebbles to help the gizzard grind food. Strong claws let them scratch in loose soil like chickens, though they rarely uproot growing plants. They are especially good at eating ticks, including deer ticks that can carry Lyme disease, which is one reason farmers use them for pest control.

Pairs form after winter, when flocks break up. Males fight hard over females, raising their wings, fluffing their feathers and rushing rivals with open beaks, sometimes leaving them bloodied. A pair stays inseparable for about five weeks, calling to each other, roosting together and preening. The female lays about 6–12 eggs in a well-hidden scrape and incubates them for 26–30 days while the male guards and feeds her. Both parents defend the keets, which can flutter onto low branches barely a week after hatching, fledge at about four weeks and stay with the family group for 50–75 days. They breed at about one year old.

Range and habitat

Wild helmeted guineafowl range across most of sub-Saharan Africa, from Senegal in the west to Eritrea in the northeast and south to South Africa. They live in warm, fairly dry, open country with scattered shrubs and trees, including savanna, grassland, scrub and farmland. They like to be near fresh water such as rivers and waterholes, need trees for night roosts and avoid dense forest, desert and marsh.

Domestication has spread the species far beyond Africa. Helmeted guineafowl are the guineafowl sold in Western supermarkets, and they are raised for meat, eggs and feathers. Feral flocks descended from domestic birds now live in the West Indies, North America, South America, Australia and Europe. Domestic birds lay very thick-shelled eggs that the keets break into fragments as they hatch. Domestic hens are not the most reliable mothers and often abandon their nests. Compared with chickens, guineafowl need more protein in their feed, which has caused growth and egg-laying problems on farms that did not understand their needs.

Conservation status

The helmeted guineafowl is listed as Least Concern by the IUCN, in a 2018 assessment by BirdLife International. It is widespread across Africa and lives in cultivated land as well as wild savanna.

In Africa it has been hunted for thousands of years and is still a popular gamebird, valued as a wary, clever quarry. Natural predators of adults and eggs include leopards, servals, wildcats, dogs, crocodiles, snakes and martial eagles. Farmers sometimes treat guineafowl as pests because they damage crops, especially young seedlings, but the birds also earn their keep by eating ticks and other insects.
