Warthog groups are called “sounders”. Most sounders are composed of females and their young. Young males live in “bachelor” groups with other males, but become solitary when they reach adulthood.
Warthogs live mostly in grassland and savanna habitats, where they feed mostly on grasses, roots, berries, fruits, and occasionally insects and eggs. Warthogs use their snouts and tusks to dig out roots and other food items when grasses are not available.
Warthogs live in burrows, usually those abandoned by other animals such as aardvarks. Thought they can defend themselves and their young with their tusks if necessary, their main defense mechanism is to run away from potential threats. Predators of warthogs include humans, lions, leopards, cheetahs, crocodiles, hyenas and African wild dogs.
