The kori bustard is the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species in the large-bodied genus Ardeotis. The male kori bustard may be the heaviest living animal capable of flight.
Region
Eastern and Southern Africa
Typical Environment
Occurs patchily from Ethiopia and Kenya south through Tanzania to Angola, Namibia, Botswana, Zimbabwe, and South Africa. It favors open to lightly wooded savannas, arid grasslands, and thorn scrub with scattered trees. The species avoids dense forests and steep mountains but uses agricultural edges and burnt areas where prey is abundant. Protected areas such as the Serengeti, Etosha, and the Kalahari support important populations.

The kori bustard is among the heaviest living birds capable of sustained flight, with large males sometimes exceeding 15 kg. It spends most of its time walking and is reluctant to fly unless disturbed. Males perform dramatic courtship displays, inflating the neck and fanning the tail while emitting deep booming calls. They are sometimes accompanied by carmine bee-eaters that hawk insects flushed by the bustard’s footsteps.

Temperament
solitary and wary
Flight Pattern
reluctant flier with slow, powerful wingbeats; usually flushes only when pressed
Social Behavior
Generally solitary or in small loose groups; males are polygynous and display on open ground to attract females. A simple ground scrape serves as the nest, and the precocial chick is mobile soon after hatching. Nonbreeding birds may aggregate where food is concentrated.
Migratory Pattern
Partial migrant
Song Description
Mostly quiet, but males produce deep, resonant booms and grunts during courtship displays. Both sexes may utter low growls and clucks when alarmed or communicating at close range.
