OTHER COMMON NAMES

French: Potamochère; German: Buschschwein; Spanish: Jabalí de río.

PHYSICAL CHARACTERISTICS

Length 39–59 in (100–150 cm); top 21.5–38 in (55–97 cm); weight 154.2 lb (70 kg) (vary 101–286 lb [46–130 kg]). Snout is elongated. Animal ranges in shade from mild crimson to brown and grey to predominately black. Newborns are darkish brown in shade with rows of sunshine spots. The tusks are least conspicuous among the many African suids; the higher tusk averages Three in (7.6 cm), whereas the decrease tusks vary from 3.5–6.5 in (9–16.5 cm) in size. Males have small warts in entrance of the eyes. There are six pairs of mammae.

DISTRIBUTION

Found from Somalia to east and southern Zaire down to the Cape Provinces in South Africa. It can be discovered on Madagascar and on Mayotte Island within the Comoros; nonetheless, it was most definitely put right here by people.

HABITAT

Generally discovered in additional moist habitats with vital vegetative cowl and have a tendency to keep away from drier, extra open areas. May occupy riverine, lowland, swamp, and montane forests in addition to woodland savannas, scrub habitat, and cultivated areas.

BEHAVIOR

Mainly nocturnal, sleeping in self-excavated burrows or in heavy thickets of vegetation in the course of the day. Those dwelling within the southern Cape have a tendency to be extra diurnal in the course of the colder months, suggesting temperature regulation could also be an necessary issue influencing the exercise rhythms in some populations. They dwell in single male household teams containing a number of females and their younger (group dimension vary 4 to 15 people), although each species have been noticed in bigger herds. Family teams are territorial, comparable to different African suids. Territorial encounters are sometimes characterised by ritualized shows and scent marking. Territory sizes differ with location and vary from 0.05–2.5 acres (0.02–1 ha). Adult males play a job in rearing and defending the younger. Males disperse from the natal group, whereas females might stay on the natal territory.

FEEDING ECOLOGY AND DIET

Omnivorous, consuming roots, bulbs, fungi, fruit, eggs, invertebrates, birds, small mammals, and carrion. They use their snouts to root within the floor and may do severe harm to crops in a short while. Field research in Uganda have discovered that bush pigs might comply with teams of monkeys as they forage and feed on the discarded fruits.

REPRODUCTIVE BIOLOGY

Polygamous. Reproduction is seasonal with younger being generally seen on the finish of the dry season or starting of the moist season. The common gestation is 120 days. Litter sizes vary from one to six, with three to 4 piglets being the commonest. Newborns weigh 24.5–28 oz (700–800 g). Females might begin breeding at two to three years of age.

CONSERVATION STATUS

The IUCN has designated this species as widespread and regionally ample or comparatively safe, relying on the subspecies. Though the bush pig continues to be comparatively widespread, its distributions are patchy in sure areas. They have been reported to be uncommon outside of protected areas, and they're extensively hunted both for subsistence or for industrial sale of the meat at native markets. In some international locations, poaching inside protected areas is a severe menace. The clearing of some forested areas and conversion to cropland has benefited this species in some areas.

SIGNIFICANCE TO HUMANS

Notorious crop raiders. They are additionally typically thought to move illnesses on to livestock. Eradication applications for these species have been largely unsuccessful as a result of they breed rapidly and are cryptic in nature. Potamochoerus does characterize an necessary supply of meat for food or income in some locations, whereas in others the meat is prevented as a result of it's thought to transmit epilepsy.
