Habits: The Southern Ground-hornbill occurs in savanna and woodlands, generally prefers more wooded and wetter areas than Northern Ground-hornbill but it also extends into adjacent open grasslands. In East Africa recorded up to 3,000 m elevation. It feeds mainly on animals that it catches on the ground. A large assortment of prey has been recorded, mainly invertebrates such as grasshoppers, beetles, insect larvae, snails, scorpions and termites. Vertebrate prey includes frogs, rodents from mice to hares and squirrels, snakes, lizards and tortoises. It will actively pursue prey on the ground, for larger prey several members in the group might hunt together. It also probes dead wood for larvae; it uses it huge bill to dig for food and stab larger prey. It also takes some fruits and will visit kills, mainly to search for bits of carrion and associated grubs. It is territorial and sedentary; juveniles will disburse across the home range on maturity.
