Otididae (bustards and korhaans)

Bustards and korhaans are found in open to lightly wooded habitats, and are found in many dry areas in southern Africa. They are omnivorous, feeding on a range of plant products and small animals, especially insects. Most species are polygynous, with the female solely incubating the eggs, and often caring for the chicks, although in the Eupodotis genus, the male participates as well. It lays 1-3, very rarely 6 eggs directly on the ground, often with enough surrounding vegetation to conceal the incubating female.
