Southern yellow-billed hornbills prefer drier habitats and are often found in deciduous woodland, scrubs and open thorny landscapes. They are often found on the ground foraging for insects, spiders, scorpions, and seeds. In the dry season they feed mainly on ants and termites. Small lizards, snakes and rodents are also included in their diet. Activity levels peak in the early morning and late afternoon, although they often stay active throughout the day. They are normally seen alone, in pairs or in smaller flocks.
