Warthog avoid tall grass and thickets. Savanna or woodland areas covered with short grass and plenty of termite mounds are the ideal Warthog habitat.
Habits
Warthog are normally seen in small family groups of one or more sows and their most recent piglets. The adult boars normally live isolated from the family groups, in small "bachelor groups". When the mating season arrives, fights between boars can occur, but normally end with the weaker animal running away from his contender. Adult boars have 2 pairs of outgrowths of thickened skin just below the eyes. Sows have only one small pair of these "warts". At night they retire to the safety of their burrow, entering always backwards, with the exception of the piglets. Leopard and Lion are the major predators of Warthog, and young piglets are sometimes taken away by big Eagles, like the Martial Eagle. The males can attain a mass of around 100 Kg and the female 70 Kg. Their lifespan is a bout 15 years.
Diet
They are mostly grazers, but can occasionally feed on wild fruits. During the dry season Warthogs spend allot of time digging for tubers and rhizomes with their powerful snouts.
Breeding
After a gestation period of 167 to 175 days, the sow gives birth to as many as 8 piglets, in the protection of the burrow, where they stay for about 2 weeks suckled by their mother. After this period they will emerge from the burrow for very short periods. Sows normally have their first litter at the age of 2 years.
