    Ardeotis

    This group comprises the heaviest flying birds and forms the threshold for how heavy flying birds can get

    Ardeotis is a genus of large, ground-dwelling bustards that inhabit the grasslands and shrubby areas of Africa, Asia, and Australia. Their sizes range from the large Kori and Australian bustards that can grow up to 120 cm (47 in) to the smaller Arabian bustards that just reach 92 cm (36 in).

    All species show sexual dimorphism – the males are much larger than the females. Clutches are small, limited to only 1-2 eggs, which are entirely taken care of by the females. Nest-building is absent or limited to simply scraping a shallow groove. They are opportunistic omnivores, most preferring to feed on insects but can also include seeds, small reptiles, and mammals in their diet.
