Common warthogs are medium-sized wild members of the pig family. Warthogs are identifiable by the two pairs of tusks protruding from the mouth and curving upwards. The tusks are not used for digging but are used for combat with other hogs, and in defense against predators. Common warthogs have a large head, with a mane down the spine to the middle of the back. Their body is covered with sparse hair and is usually black or brown in color. Tails are long and end with a tuft of hair. Females in this species are typically a bit smaller and lighter in weight than males.



Common warthogs are found in sub-Saharan Africa. They live in grasslands, savanna, open bushlands, and woodlands. These animals prefer open areas and avoid rainforest, thickets, cool montane grasslands, and severe desert.

Habits and Lifestyle

Common warthogs are social animals and live in groups called sounders. Females live in sounders with their young and with other females. Females tend to stay in their natal groups, while males leave, but stay within the home range. Subadult males associate in bachelor groups but live alone when they become adults. Adult males only join sounders during the breeding season. Common warthogs are not territorial but instead occupy a home range. They have two facial glands: the tusk gland and the sebaceous gland. They mark sleeping and feeding areas and waterholes. Common warthogs use tusk marking for courtship, for antagonistic behaviors, and to establish status. These animals are the only pig species that has adapted to grazing in savanna habitats. They are powerful diggers and use both their snouts and feet. Whilst feeding, they often bend their front feet backward and move around on the wrists. Although they can dig their own burrows, they usually occupy abandoned burrows of other animals. When temperatures are hight Common warthogs enjoy wallowing in mud in order to cool themselves and will huddle together to get warm when the temperatures get low. Although capable of fighting, the Common warthog's primary defense is to flee by means of fast sprinting. However, if a female has any piglets, she will defend them very aggressively.

Seasonal behavior

Diet and Nutrition

Common warthogs are omnivorous but also scavengers. They feed on grasses, roots, berries, and other fruits, bark, fungi, insects, eggs, and carrion.

Common warthogs are polygynandrous (promiscuous), which means that both males and females have multiple mates. They are seasonal breeders and rutting begins in the late rainy or early dry season. Males have two mating strategies during the rut. First is the "staying tactic", when a male stays and defends certain females. In the "roaming tactic", males seek out ready to mate females and compete for them. A dominant male will displace any other male that also tries to court his female. When a female leaves her den, the male will try to demonstrate his dominance and then follow her. When females are about to give birth, they temporarily leave their families to farrow in a separate hole. The gestation period is 5-6 months and the litter is 2-8 piglets, with 2-4 typical. The female will stay in the hole for several weeks, nursing her piglets. Common warthog females may also nurse foster piglets if they lose their own litter. This behavior is called allosucking and makes them cooperative breeders. Piglets begin grazing at about 2-3 weeks and are weaned by 6 months. Young quickly attain mobility and stay close to their mothers for defense. They become reproductively mature at 18-20 months of age.


Population threats

Major threats to Common warthogs include droughts, disease, and hunting. In eastern Africa, these animals suffer from habitat degradation, loss and fragmentation, and competition with livestock for water and food. Common warthogs are hunted for bushmeat, entertainment, skins, and tusks, as bait for hunting large carnivores, for crop raiding, or to reduce grazing pressure.

Population number

According to the IUCN Red List, the total population size of the Common warthogs is unknown. However, there is an estimated population of the species in South Africa which includes around 22,250 individuals. Currently, Common warthogs are classified as Least Concern (LC) on the IUCN Red List but their numbers today are decreasing.
