Being primarily a terrestrial bird, the kori bustard is reluctant to fly unless in serious danger (2) (4) (8). Like other bustards, it forages on foot, taking a wide variety of food items including grasshoppers, dung beetles, small reptiles, rodents, seeds, roots and wild melons (4) (6). Often it will follow herding animals, feeding on insects disturbed by the herd’s movements, and will also be quick to inhabit recently burnt areas, where it feeds on new grass shoots and exposed animals (2) (4).
During courtship, the male kori bustard struts about with its crest raised, its neck inflated, and its tail feathers cocked (4) (7) (9). In addition, on approaching an individual female, the male will sometimes bow low, whilst emitting a low-pitched booming sound. Being a polygamous breeder, the male resumes its courtship display following copulation, having nothing more to do with egg incubation or parental care (9). The female incubates one to two eggs in a shallow scrape in the ground for 23 to 24 days before hatching (4) (9). The chicks remain with their mother well after fledging, and only reach sexual maturity after at least two years (9).
